Pokémon Stadium Kaizo

The Ultimate Pokémon Challenge
BPS Link:
(See at the bottom for details)

Pokémon Stadium is a game that I enjoyed, and is what kept me into the Pokémon Series.
This is the very first Pokémon Stadium hard mode hack that has some key features. It is nonprofit passion project.

1. Vastly Improved Rental Pokémon:

Poke Cup Rental Nidoking, with a good movepool and stats.

Petit Cup Rental Oddish, with a level increase to differentiate itself from other grass types. Many Pokémon in different cups have this.

Pika Cup, with as much variety as legally possible in both the Japanese Version, Default Wild Move, Yellow, Tradebacks, and Ingame trades with breeding. This is one of the cups with exclusive unevolved rental Pokémon not found in most cups.

Some Rentals may have nicknames of their Pre-evolutions. They have different movesets for additional variety. This hack factors in emulators that may not be able to utilize the Transfer pack, Much better than the Original Game's rentals. That is a good thing in this game.
2. All Pokémon can be registered in the Hall of Fame:

That's right! Without a transfer pack, it is actually possible to register all Pokémon to the Hall of Fame. It will take a little more work because some Pokémon are only found in certain cups, particularly unevolved Pokémon, but you will have to beat Round 1 in order to access the Round 2 cup with one more rental. Now R2 in the original is infamous for its difficulty, and there is Kaizo in the title so...
3. Enemy Trainers are SIGNIFICANTLY HARDER than the Original Pokémon Stadium:

I'm not going to lie. If I didn't change those rentals, this would be impossible to beat.

Right from the start, your enemies will have fully evolved Pokémon. The only exceptions are Pokémon that have moves or stats, or in a couple of cases, typing, that enable them to be better than Butterfree, or even several mid-evolutions. The ascending difficulty of the cups determines the quality of the moves or fully evolved Pokémon you face.

Single level cups such as Petit Cup and Pika Cup will often start out a bit harder than the others, some with wildcards that somewhat fit the theme or stratagem of the trainer. Also, nicknames of enemy poekmon are changed. You can laugh and make fun of me if you want if you find a name silly, and repeatedly used, but this makes them stand out (and some may be better than the original nicknames).

Difficulty Factors:
A. The AI is changed for nearly every single trainer.
B. The Teams are revamped. Bosses in Gym Leader Castle will have Wildcards, and Often their Signatures. If not, then their underlings may use them.
C. Movesets are changed to compliment the AI and their strategies. Many are universally threatening, but some may try some gimmicks, or unique strategies to them.
D. And of course, the enemy stats are raised higher than Round 2 Pokémon Stadium 1.
E. Think of Pokémon Stadium Kaizo R1 as R3, and Kaizo R2 as R4.
F. Kaizo Round 2. Apart from many relentlessly cruel battles that can make you question the validity of your existence, there are some unique battles in every cup that you can encounter, usually on the fourth battle in the Stadium Cups, and quite a surprise near the end of Gym Leader Castle Round 2.
G. Continues? (See Below)

4. Continue?
You might think it may be like the Pocket Monster's Stadium version where there are 42 1997 Nintendo Cup staples and no continues. In the Stadium Cups, that is still not the case; as long as you can manage perfect wins, you can still earn continues. There is also quite a bit more variety early on. You most likely won't face those monsters until Ultra Ball. A blessing because some fights can possibly checkmate you.

Sadly for you, Gym Leader Castle has no continues, and every single trainer is more threatening than before, though that's not saying much. Some are easier than others, but you can expect Gym Leaders to put up a fight. Especially the Elite 4.
Now if you feel like your emulator may crash or something might interrupt you, you are encouraged to save state. If you feel like resorting to save states as infinite continues, or even mid battle, you probably shouldn't consider thinking the game is easy at any point.
5. Achievements:
Unfortunately you don't really get exclusive prizes different from what you get for the transfer pak, assuming you are even using one. That is why I'm throwing in a little achievement list. Its not much, but I will list you on if you pull it off.

a. Beat R2 Mewtwo
b. Surfing Pikachu challenge
c. Rental Only run
d. Get all 151 Pokemon in Hall of Fame
e. Secret achievement (This is mostly in regards to those who use the transfer pack, I'll mention you achieved it as long as you AVOID using certain moves. I won't reveal which, but thankfully it is extremely few.
f. No continue Run (Pocket Monsters Stadium challenge: Go through a tournament cup without losing AT ALL.) Good luck with this one if you are really bold. Because "Nuzlockable" this game is not.
g. Assist people in getting Pokémon Stadium Kaizo to run.
(This is a nice gesture to other people, and I will credit you most on this, especially the first one. Emulators can be finicky things, so make sure to list specific ones, because this rom might have trouble working on emulators without changing emulator settings. I'm still new to that aspect myself)
6. The Download Link:
The patch file is stored in a zip file. WinZip is needed to open it.

This is slightly a bit different from IPS. You will need a BPS file or FloatingIPS, which patches z64 files.
It is mostly the same as patching with the IPS file: Rom base, the patch file, an emulator, but you'll also generate a brand new file.

However, there may be some issues. You'll need the new checksum, two CRCs to change in the RDB file somewhere in the Project64 configuration file/program file? That is because there is one battle data change that did cause the checksum to be different. It may not matter in other emulators outside of Project 64. If you can provide assistance in getting the Project 64 hack to work, (especially if you have video proof of it working for Project64 on youtube) please let us all know in the posts. I'll make sure to credit you all.

BPS link:


This BPS file works with PJ64 no problem. No RDB nonsense, but I was extremely hesitant due to an exploit in the original Pokémon Stadium.

WOW! This really caught me off guard. Pokemon Stadium was a favorite of mine but the crappy move-sets of the rental mons often kept me away. It would have been far better if you made a Kaizo of Stadium 2 tbh but nonetheless I am sure this will be enjoyable.
Track Number 2 of my debut Mixtape, Venting Session Vol.1:
What's it like -
A lot of emotions, thought and a bit of nostalgia went into the making of this particular track on the Mixtape.

Found a problem here. Went to Poke cup and when I selected one of the nicknamed Charizards (The Charizard nicknamed Charmeleon, specifically), the game crashed. Again with the Blastoise named Squirtle
The game crashed because the of the new checksum, which I mentioned in the text file accompanying the bps. The nicknames don’t cause it, but the RDB file needs to be updated with a near identical entry with the Original CRCs, only the new entry needs the Old CRCs replaces with the new. The region code is the same. The tricky part is where to place the entry with the new CRCs, and most likely HOW to edit the RDB file. This glitch happens for Project 64, and is common with many N64 hacks. Most likely why Pokemon Stadium hacks are almost nonexistent for PJ64.

As if Pokémon Stadium wasn't hard enough as is.

Also, curious as to how you'd use a transfer pack on an emulator? Is that a known thing?
The only emulator I know that can’t use the transfer pack is the 1.6 version of Project 64. Later versions can have transfer pack compatibility, and I do believe many other N64 emulators have it as well.

Gotta have the rby files, the emulator with a transfer pack plugin, and you’ll be able to use cartridge Pokémon in Pokémon Stadium Kaizo.

Notably, Poke Ball and Great Ball difficulties in Stadium Kaizo Round 1 are roughly as hard, if not harder, than Round 2 Ultra Ball in the original Pokémon Stadium. Kaizo Ultra Ball, let alone Kaizo Master Ball R1, might be harder than the Nintendo Cup 97-98 rounds in the Japanese versions of Pokémon Stadium.

You don’t even want to imagine Kaizo Round 2.

Great job, I'll try the ROM hack right away :)
Now I have another reason to resume work on the editor ^^

Edit: I saw in your video that some Pokémon like Charizard have pink moves like Rock Slide. You can either fix that by editing the learn sets, or by removing the checks in this subroutine.

Is there a way to ban or unban certain Pokmon without changing the CRC? Or ban a specific move where it does not change the crc?

I would like to release a much more user friendly easy to patch mod, without dealing with the muk that is RDB file editing, because I hate to admit, Im having issues with this.

I figured out how to create and use custom pokemon for Pokemon Stadium Kaizo on PC and Android. The instructions are below. If there is an easier way, please post it.

Programs/files needed:
• Pokemon R/B/Y ROM
• GB emulator e.g. VBA-M
• Rhydon RBY Save Editor
• Pokemon Stadium Kaizo ROM
• Project64 1.6 or higher
• NRage Input Plugin v2.
• Mupen64Plus FZ for Android. I recommend using Glide64-Medium emulation profile.

1. Open Pokemon R/B/Y ROM in GB emulator, save in a Pokemon Center.
2. Open the SAV file in Rhydon.
3. Create and set pokemon. (Can use smogon website to lookup movesets/available moves.)
a. Select desired species, nickname, level, moves, PP ups, DVs (max = 15), stat exp. (max = 63504). For trainer information, copy TID and trainer name from trainer tab.
b. Right click a position in party/box and set.
4. Export the SAV file. Can open in GB emulator to make sure it worked.
5. In Project64, select Nrage Input Plugin v2, configure controller plugin, controller pak tab, check raw data, transfer pak, set Pokemon R/B/Y ROM and SAV files.
6. Open Kaizo ROM and you will be able to select your created pokemon from cartridge.
7. To use your created pokemon on Android phone: Open Kaizo ROM in Project64 and register team(s) containing your created pokemon from cartridge in desired mode(s).
8. Copy the FLA save file (default location: C:\Users\[User]\AppData\Local\VirtualStore\Program Files (x86)\Project64 1.6\Save\), rename to "POKEMON STADIUM (unknown rom).fla", then transfer to your Android (default location: /storage/emulated/0/mupen64plus-fz/GameData/POKEMON STADIUM…/SramData/).
9. In Mupen64Plus FZ, open Kaizo ROM, go to mode with your registered pokemon, and play.

I can send anyone a copy of my file and can share it on my Google Drive send me a private message and I’ll send you a copy to play Pokémon Stadium Kaizo but this is for PC only. I don’t know if this will work on a Mac

My other question for the OP.

Will you be making a Pokémon Stadium 2 Kaizo ( with the johto Pokémon) ?

Is there a way to ban or unban certain Pok�mon without changing the CRC? Or ban a specific move where it does not change the crc?

I would like to release a much more user friendly easy to patch mod, without dealing with the muk that is RDB file editing, because I hate to admit, I�m having issues with this.
Huge bump to this thread, most of the posters on this thread have commented with issues on getting the game to work.

I just wanted to say thank you for the marvelous job in creating this. I have been playing it myself for the past week in my free time and I have had lots of fun. (And of course, lots of patience) I love Pokemon Stadium and being able to use rentals that have good movesets makes the game SO much more enjoyable! Again, thanks for sharing this with the public, it's tremendous work and REALLY good!

I'd like to share my progress thus far in case anyone is interested in playing this game, cause it's still pretty fantastic. So far, I have completed Gym Leader Castle, Elite Four&Rival, Pika Cup, and Petite Cup all in round 1. I'll give an update on Poke Cup and Prime Cup whenever I get to that, and obviously I'm expecting Round 2 to take much more time so...

First off, I'd like to say that I have only used rentals (I just didn't bother with using Transfer pokes, I find that less fun). I used Project64 to play the game and a gamecube controller.

Here is my Round 1 Kaizo Run Summary so far, and some constructive critiques for the game:


Gym Leader Castle:

The majority of the gym leader castle is essentially free, as long as you pick the best gen1 pokes on your team, which would be Starmie, Zapdos, Tauros, and maybe Alakazam or Mew (up to preference). My other two pokes were
Nidoqueen and Charizard as niche picks for certain situations and team balancing.

Quick note: Make sure if you run into a team with Chansey, you bring two attackers. Like I would always bring Tauros and Zapdos to those fights. And remember, the recently found gen1 mechanic says if you Body Slam a normal
type i.e. Chansey, it will never paralyze (something with the game's code states that since body slam is a normal type move, the after effects won't occur vs. other normal type pokemon)

The first roadblock I ever ran into was Giovanni's gym. The lab man (2nd trainer) is just brutal. I had to switch my Nidoqueen for Golem instead, because the poison typing was bad for Alakazam (I stuck with Golem thereon). Basically, I would choose Tauros, Zapdos, and Golem for this fight. Start with Tauros because typically he started with Chansey. His Chansey will use moves in this order: Light Screen, spam Soft-Boiled if not at full HP (and CPUs dont lose PP in gen1), Minimize, and then after maxing evasion spam Seismic Toss. So, my Tauros can use Body Slam while Chansey uses Light Screen and then Hyper Beam for just enough to kill. Here's the catch. After that, he will send out Alakazam. While Tauros recharges, he'll be T-waved. Then, Alakazam starts Double Teaming. I switch to Golem, and basically before I use explosion, he will get off two double teams. So I had to grind hitting an Explosion. After that, I switched into Zapdos and he had starmie left who just spammed Minimize while I 2HKO'd it with Thunderbolt. That Lab Man is brutal.

Other than that trainer, the gym leader castle is pretty easy. Starmie is just an amazing pokemon, so bring along Starmie. Personally, I liked the coverage, so I picked the psychic, surf, ice beam, tbolt set.

Elite Four and Rival:

This is where its just ridiculous. I was on this challenge for a few days. To save yourself from sanity, use save states. Otherwise, good luck. Patience is key with this. The only huge challenges for me were Agatha and Gary. Agatha had a nasty Alakazam that she always ended up using and Gary had a Mew that was also pretty brutal. For these fights, I used a combination of an Alakazam of my own and Golem. Typically, I would T-wave the opposing pokemon, switch into Golem and explode. For Mew, you need to get off one earthquake before you decide to explode. I kind of forgot the big details of those two fights cause they didn't stick out in my head as well as the Lab Man fight did in the Gym Leader Castle, but you really have to be prepared.

This is the toughest roadblock I had thus far.

Pika Cup:

I would suggest to only bring along two Level 20 pokemon. Because then, you can choose from four different lv15 pokes per match. The trick is, a lot of these trainers have like four lv20 pokes, but theyre only allowed to bring one along. So, you will already know TWO of the pokemon that these trainers bring right off the bat, which will be there two lv15 pokes. The lv20 pokes I chose were: Starmie and Pikachu. You NEED to have level 20 pokes brought along with you, theyre power difference is pretty massive. Having lead level 20 Starmie is absurd, just broken. Every single match was a free win for me using Starmie (I actually used Pikachu for one of them cause the other trainer had an opposing lv20 starmie but never used it in my tries)

I DEFINITELY used my continues for all the attempts I did and here's why: The last two trainers are pretty ridiculous. The semi-finals trainer, Lass, always brings along either lv20 Raichu/Dragonair, which both have T-wave and amazing special to counter Starmie. And then she ALWAYS brings Lapras and Arcanine, two bulky mons equipped with Dragon Rage. The only time I beat her was when I got lucky special drops on Raichu and when she actually chose her lv20 Mr Mime, which was easier to take care of.

The finals battle is atrocious. The trainer ALWAYS picks the same broken ass lv20 alakazam in the vanilla version of this game and you have no idea what lv15 pokes he brings cause he has four of them now. Litterally, my win condition was this: Hope he doesn't pick Execuggtor. The lv 20 Alakazam was already enough to take care of. So having another broken mon that tanks a lot of hits is not what you can afford, its just a loss. Hope he leads Aerodactyl. My team was lv20 Pikachu, Tauros, and Golem. I lead Pikachu and he lead Aerodactyl. He immeadietly switches into Alakazam as I use T-bolt (I think if you use T-wave he stays in and uses EQ). I switch into Tauros and die to a Psychic. I needed a free switch into my Golem. Switch into Golem and Golem always barely tanks one Psychic. Tank a psychic and use Explosion to kill the Alakazam. Now, Im left with just lv20 pikachu because I litterally needed to pokes to kill that absurd Alakazam. Pikachu one shots Aerodactyl with T-bolt cause level difference. Clefable is the last mon, I use t-bolt, it uses twave. Then I use twave while it uses body slam. We both deal the same damage essentially. In the end, I win the para war and thats game. Thankfully, the AI doesnt switch into Clefable and t wave first because Aero has EQ. Pika cup will give you much trouble... but with continues its not as bad as Elite Four&rival was.

Petite Cup:

This place took the most re-entering for me, more than Pika Cup did. Because of Starmie, I was always able to get 3-4 continues under my belt prior to the semi-finals and finals matches. I don't know
if it's because I have less competitive knowledge in Little Cup or what, but I maybe got one continue in all of my attempts. And every trainer was a problem in some way shape or form, but not a problem
to where it was totally un-doable. I would get critted or para'd or just out-teamed in situations most of the time here, maybe it's just the nature of Little Cup that its harder to take hits. Either way,
I actually started off with a team full of pokes that I thought had some insane skill. My first team was Voltorb, Paras, poliwag, sandshrew, growlithe, and dratini. Voltorb is just good in general, with
access to T-Bolt, Explosion, decent Special, and incredible Speed, for me its a must have. Paras was hidden talent to me, I never thought I'd use it. But its actual a great tool for say, if you lead Voltorb,
and the opponent leads a ground type (which happens so often), its a free switch into Paras and a free Spore. And in gen1 Spore also hits grass types, so opposing Paras gets put to sleep aswell and theres a free
switch into growlithe with a free dragon rage/fire blast. Poliwag and Sandshrew were for team balance and I felt they had the best stats, with Poliwag having access to Lovely Kiss. Growlithe and Dratini
were both devastating Dragon Rage users, and they complimented each others weaknesses very well, so dual Dragon Ragers came in handy.

Then, I decided to make a huge flip in my team. I realized that Paras was just too slow and Pokemon often found workarounds. Both Paras and the growlithe/dratini method were weak to common Water types with
access to water and ice moves simultaneously. The team just wasn't cutting it, ground types even had rock slide or a suprise Blizzard, so Paras got hit by those often too with its abysmal speed stat.
Which meant ground types really had a field day with my team. Same with water types, Paras started to not be a very good check. Therefore, I restarted to fix my team composition completely, and looked
more carefully at stat spreads and movesets.

I changed out every Pokemon except for Voltorb. My final team was Voltorb, Abra, Goldeen, Geodude, Farfetch'd, and Nidoran-Male. I was hesitant on Abra since in gym leader castle mode, my Alakazam was
frequently outclassed by Starmie for its lack of Defense and hitting Super Effectively more often. But, in Petite Cup, Abra proved to be a good force to be reckon with. It was a great lead, that had very
nice speed and immeadiete power. Frequently, I would begin games just throwing off as many Psychics as I can team keep the momentum and kill mons. It's T-wave came in handy for Geodude to come in and
use heavier Attack stat moves too. Goldeen was chosen over Poliwag this time, as I prefered the extra bulk, extra special, and access to Double-Edge with a good attack stat against other Water types over
Poliwag's great speed and access to Lovely Kiss. It proved to be more viable in many situations, and I used double-edge a lot more than I thought. Geodude was taken over Sandshrew for access to Explosion
and better stats, although it has the nasty rock/ground typing, it helped a few times with opposing bird types. Farfetch'd was put on the team for team composition. If I wanted to go lead Voltorb, the enevitable
ground type switch in would be no problem, since I could switch into Farfetch'd. I liked this bird over all the others because it has decent bulk to take a few hits from the ground types, while also dishing out
decent damage and still outspeeding. Nidoran-Male wasn't used exactly too often, but a few times it helped since it has the extra two levels and offers bolt-beam coverage.

Shockingly, I actually did a continue-less run completion on this with the final team I made. This is because I barely ever got continues, so it was a grind but I ended up actually getting it with decent
luck along the way too. The final battle was actually really easy, I lead Abra knowing the npc would either lead Abra/Gastly since he has to pick them everytime. When they do so, all I do is click T-wave and switch into
my Geodude and its a free kill or free hit on lv30 mon. He switched into Dratini to take the EQ, then I switched into my Voltorb tanking the Blizzard. Bam, exploded on the dratini (got a crit aswell and killed it), and
my Geodude easily cleaned up the para'd Abra and Gastly with earthquake 1hkos.

The hardest match was the 6th trainer for me. I don't know why either, just had the most trouble with this one.


1. For a Kaizo, this game is only slightly worse than the original game so far. I don't really know how Round 2 is exactly cause I haven't gotten there (I'd imagine it's significantly worse), but if you want to truly make an insane Kaizo, I would suggest having the strats that the Giovanni "Lab Man" had on every single trainer. Stuff like that which encourages significant hax gameplay. Or even hacked moves on these Pokemon that would never be there otherwise, I feel like I remember the original Pokemon Blue Kaizo had all these mons running around with moves they werent actually meant to get. Maybe just absurd stats (although thats a bit much at that point, at least change the poke's level to indicate that). Also, another thing to make it harder is to just keep the rental mons at their original (although for me personally, I wouldn't enjoy this. I love the rental mons so much lol). Just suggestions on making the game harder because I litterally beat all the gym leaders in one day with barely much trouble. This is PRIMARILY because the rental mons are now actually good, with movesets that don't force you to play with Thunder and Hydro Pump and moves that just miss all the time. Definitely made Pokemon Stadium much more enjoyable with less hax this way then I usually see from say Werster's runs.

2. The Petite Cup cast seemed pretty balanced for the most part while the Pika Cup had mons that purely outclassed other mons. I understand why someone would pick Raichu over Pikachu even though the lv20 Pikachu is better in every front, so that they dont waste a lv20 slot. That makes sense to me and I enjoyed that decision making a lot. But in the Petite Cup, it has that same thing except all of the lv30 or lv27 mons were just utter garbage and it was more just balancing the meta? I liked Pika Cup's idea, but if you do want to make Pika Cup more difficult you could also try just balancing mons instead of giving lv20 leisure. Plus, lv20 Starmie is broken, straight up.

3. Something I noticed a lot in Pika Cup is that there would be four lv20 mons and two lv15 mons. I feel like it would be better if there were maybe 3-3 or 2 lv 20 mons and 4 lv 15 mons. This gives the AI a lot of leisure to mix up the teams, making them significantly harder to beat. It's way easier to counter all these teams when they can only leisurely choose to change around one pokemon, but theyre always stuck with the same other two lv15s. Just a way to make things more difficult.

I don't know if any of this stuff changes when you get to Round 2, but that's some of the things that could make the game more difficult or more enjoyable. I obviously don't think you should fix any of this in the current game at all, I'm just hoping you carry something forward in whatever next project you decide to do, whether it be Pokemon Stadium 2 Kaizo or something else you're interested in.

Good luck with any future projects! I'll keep playing this game probably in my free time, but I start my full-time job in a week from now, so I hope I can finish round 1 before then
