FireRed hack: Pokémon FireRed - RNG Strikes Back

Pokemon FireRed - RNG Strikes Back

Hello Pokécommunity! I am Mechakhan and today I present to you yet another ROM hack of Pokémon FireRed.
This hack follows the same story as Pokémon FireRed. However, as you play it, you'll have the worst luck you can possibly imagine. Everything from critical hits to the rate you'll be receiving eggs from the Day Care has been altered to be against your favor. This is a complete list of what's been modified:

Spoiler:

In Battle: (All the effects mentioned here is reversed when an ally is targeted.)

Spoiler:

• Critical hits: You will never land a critical hit, your opponent will always land critical hits.

• Damage Range: You will always get the lowest rolls, while your opponent will always get the highest rolls.

• Accuracy: If the final accuracy (move accuracy, accuracy/evasion drops/boosts, Brightpowder, Sand Veil etc factored in.) is less than 100%, you will miss, your opponent will never miss.

• Secondary Effects: If your opponent uses Ember for example, it will always cause a burn. You will never trigger any secondary effects.

• Poké Balls: If the chance of catching a Pokémon is not 100%, the odds of every successful Poké Ball shake is halved. This is because it would be impossible to catch Pokémon before Brock otherwise, which would make Charmander impossible to pick.

• Sleep: When put to sleep, your Pokémon will sleep for five turns, while the opponent will only sleep for two turns.

• Paralyze: If you get paralyzed, you will never be able to move. You opponent will never get fully paralyzed.

• Freeze: If you get frozen solid, you will never defrost. Your opponent defrosts immediately.

• Confusion: You will always hit yourself in confusion for max damage and stay confused for the maximum amount of turns, while your opponent never hits themselves in confusion and snaps out after the minimum amount of turns.

• Infatuation: You will never be able to move when your infatuated, but your opponent will always be able to move.

• Speed ties: You will always lose speed ties.

• Fleeing: You can't flee if your speed is lower than the opponent's.

• Disobedience: Your Pokémon will always hit themselves in confusion when they're disobedient.

• Contact Abilities: Static, Flame Body, Poison Point, Cute Charm and Effect Spore will always activate for your opponent, but never for you. Effect Spore will never affect you with a status that you're immune to.

• Shed Skin: Shed Skin will always activate for your opponent, but never for you.

• Disable/Encore/Trapping Moves (Like Bind or Fire Spin)/Thrash Moves: These will last the minimum amount of turns when you use them and maximum amount of turns when your opponent uses them.

• Multi-hit moves: Multi-hit moves will always hit twice when used by you and five times when used by the opponent.

• Metronome: Metronome has normal effects when your opponent uses it, but it will turn into Splash when you use it.

• Tri Attack: Tri Attack will randomly cause freeze, paralyze or burn status effect when used by the opponent. It will never affect you with a status that you're immune to.

• Magnitude: When Magnitude is used, it will be a 4 if it was used by you and a 10 if it was used by the opponent.

• Present: When used on the opponent, Present will recover their HP. When used on you, it will have max base power.

• Psywave: Psywave will do maximum damage against you and minimum damage against your opponent.

• Protect/Detect/Endure: You will never be able to use these moves twice in a row, while the opponent can use them without fail.

• Spite: Spite will reduce opponents PP by 2 when used by you and your PP by 5 when used by the opponent.

• Items: Quick Claw, Focus Band and King's Rock will always activate for the opponent, but never for you.

Outside of battle:

Spoiler:

• Illuminate/Stench/Cleanse Tag/Pickup: These have no effect.

• Day Care: You won't be able to receive eggs from the day care.

• Individual Values: All Pokémon you obtain will have an IV of 0 in every stat.

• Slot Machines: Slot Machines will always have the lowest chance of payout.

• Shiny Pokémon: Shiny Pokémon cannot be found.

Also, the following changes, unrelated to the RNG, has been made.

Spoiler:

• Tackle has been set to 100% accuracy, since the early game would be impossible for Bulbasaur or Squirtle otherwise.

• Pokémon exclusive to Leafgreen can now be found in the wild. This is just to make the hack more version-neutral.

A few examples of these modifications in action:

Spoiler:

Secondary effects, critical hits and paralyze:

Accuracy and confusion:

Magnitude, Metronome and targeting ally:

Pokémon exclusive to Leafgreen found in the wild:

Bugs:

Spoiler:

Damage when hitting oneself in confusion was erroneous, fixed in version 1.01.
Yawn sleep turns were random, fixed in version 1.01.
Uproar had the effect of Tri Attack, fixed in version 1.02.
Shiny Pokémon were unintentionally possible to obtain (Thanks to Ben251 for discovering this!), fixed in version 1.03.

Many thanks to JPAN and his research about FireRed's Battle data RAM structure, which made reverse engineering the battle routines a lot easier.
I would also like to thank MissingnoXpert, who came up with the idea for this hack in the first place.

If there is anything RNG related I've forgotten about or if you've found a bug, please let me know and I'll upload an updated patch.

That's about it. Give it a shot if you want an unfair challenge, or... I dunno, if you like getting haxed for some reason. :P

This is cruel. Pure evil O__O

could 0HKO moves always land?
does focus band work unlimited number of times?
does protect/detect work 5 times in a row?
does ancient power / silver wind always raise user stats?

1. Yes
2. Yes
3. Generation 3 has a glitch that makes Protect, Detect and Endure access random data and treating it as a percentage chance for the move to work. Since the maximum amount of PP any of the moves can have is 16, and the random data that is accessed during those 16 uses of the move is never 0, it is possible to, in theory, successfully use protect until it runs out of PP. In conclusion, Protect, Detect and Endure will never fail.
4. Yes

this sounds like a cool challenge but i cant get it to work. In the very first battle my pokemon is a bad egg and attacking with it freezes the game or crashes it. It doesnt matter which starter i choose

 

[Ben251]

I found a shiny kokuna in the wild lol, so the no shiny thing seems to be broken

Hello, the CIA called, they want their torture chamber back.

That is strange. Are you using a Firered 1.0 ROM when patching? If it says "presents" under the GAME FREAK logo in the opening, it's 1.1, which is not compatible with the patch.

That's a really cool idea,looking forward to play it.

Thanks a ton!

Actually, you're completely right! I just checked my code and I made an oversight. I'll see if I can upload a patch that fixes this. But congratulations for finding an "impossible" shiny lol!

This was an interesting way of fun. I beat it with this team https://imgur.com/aYVRzqd
I played on Set Mode while not using items during battle. I also disabled EV gain because EVs are unfair vs 0 IV 0 EV opponents with bad sets. I also tried to not overlevel.
I like how despite the whole game revolving around RNG, theres actually no RNG in practice. This has been the most consistent battling i've done in a FRLG environment.
-----------
For the most part it was a decent challenge but there were a couple notable terrifying opposing pokemon:
-Misty's Starmie:
Has vastly superior stats than anything you can have, and will always outspeed and oneshot you with water pulse. And even if you survive you are confused, so basically dead. Apparently you can manipulate the AI into using swift on a grass mon so that you can whittle it down that way. Although most of my damage on it came from the level 29 dugtrio i caught in diglett's cave (yes i had to skip her to go get that).
-Catching a wild Dugtrio in Diglett's Cave(renamed to Hell):
Its not only about the decreased catch rate. If you dont overgrind, you'll be at around level 21-22 by the time you reach there. It WILL outspeed you, ohko you with nearly every move, you won't be able to swap mons around. To catch this i needed to sweet scent with gloom, die, revive and sweet scent again, die, then use stun spore with Paras (resists ground x4) before lowering it to red HP to make it possible to catch. Before it kills me.
-Surge's Raichu:
Double Team makes it invincible. It will use double team on dugtrio's Dig turn so your only option is mud slap which will deal less than half. I used Sweet Scent with Gloom until it died, this let me use Dig without worrying its evasion would go over +0.
-Koga's Muk:
Survives everything you have, and WILL use Minimize to become untouchable unless you have Swift/Shockwave. After having my patience tested, i taught Taunt to my Primeape.
-Lance's Aerodactyl:
Outspeeds everything you have and Ancientpower procs 100% of the time to make it unbeatable. The only way i got past that was because i manipulated AI to use Hyper Beam which gave me a free turn. If that didn't work i would have
dropped out of the league, and gone to replace my Raichu with a Jolteon.
-Honorable mention: Every Alakazam with Psychic. There aren't many, they're basically just Sabrina's and Blue's. I say honorable mention because I didn't have much trouble against them due to having Starmie(best mon in this mod), one of the
probably 2-3 pokemon that can 1v1 them in this mod. Everything else gets outsped and OHKOd.
-Champion battle was a trainwreck that was entirely my fault because i practically had 4 proper mons and 2 fodders. Starmie was failing to OHKO Arcanine and was getting OHKOd by Bite. Blastoise has Bite too. Blue must really hate Psychics. I had to teach Rain Dance to Raichu and Sunny Day to Primeape to beat this. Something i never needed before. It felt like an actual final boss.

Thank you for making this.

Thanks for sharing, and I'm glad you enjoyed the hack! Totally agree that Misty's Starmie is borderline impossible to beat and I also had to skip her. I used a Sandslash with Swift which dealt with Surge, and a Snorlax with Shadow Ball and Counter which dealt with Alakazams and physical attackers respectively (after taking a massive hit first ofc). And Rain Dance + Thunder is another must-have. For me Loreli was especially brutal with Ice Beam freezes. I had to use both an Explosion Cloyster and a Thunderbolt Lapras with freeze immunities and Shell Armor to win.

 

[Helko2012]

How to download it and play it on my boy ???

 

[Helko2012]

Please help it is saying user interaction required, what do I do ????????

 

[Voido]

Is it me or stats boost on your pokémon doesn't do more damage on opponent? I mean, i gave an X-Attack to go +1 but didn't change the damage roll.

 

[shock komment]

sorry i'm not able to patch anything 😣 is there a way to download the already patched rom?? thanks

Suggestion: You should make pokemon have a 100% chance of being encountered as a shiny whenever you encounter them whilst having no pokeballs (and maybe give them IVs of 31 as well...)

You are the embodiment of evil.

I think you should implement modern game mechanics and make the game a little bit nuzlokable
