FINALLY it's here again! I remember the first time I downloaded the leaked version all those years ago. I'm sure it will even get better in your capable hands :)

 

[Tendoman77]

Wow never expected this to make a return to the PC Fourms after what happened all those years ago, been following you RainbowDev guys since then so I'm glad to see Prism is finally making a proper comeback in public at long last.

 

[TheEndOfTheRoad]

Hell yeah, welcome back Prism. We missed you. ♥

 

[Danidark97]

He's back? Oh my god shit!

Welcome back, you were missed.

I'm not sure I even want to know what happened for Prism's thread to vanish from these forums :) But I'm glad to see my favorite GBC rom hack back.

I think the version I've played was 0.93. Does this new version "complete" the second region? Because the Naljo part was great when I've played, but the quality drop on Rijon was so big I dropped the game after my 10th or 11th badge.

I may get some parts of the story wrong here due to lack of memory, but the original creator who I assume is no longer around had the official 1.0 release ready back in 2016 and was even a day away from releasing it to the public, but then got caught by Nintendo with a C&D and had to cancel it along with completely trashing the version of the hack itself. Someone leaked a older unfinished version of Prisim not too long after and RainbowDevs have pretty much taken over development since then.

Prism was supposed to be released on Christmas of 2016, and despite it being in production for nine years, Nintendo waited four days before Christmas to put a C&D order out, like they were daring him to release it.

Back in the old days when Prism was using Gold as a base, it had so much potential even then. It's nice to see how far it's come.

Well least I was close lol, thanks for clarifying the rest of the details.

And dang forgot that it started out as a hack of Gold, really is doing a ton better since the move over to Crystal now

My favorite ROM hack now in PokeCommunity, let's go!

 

[Sun Moon]

I never thought this day would actually come... The near-full release of Pokemon Prism. This is a history-making moment!

Main game wise, yes. Th postgame has plenty of work tat needs to be done, at the moment it's just a large open world.

 

[Kip]

Thank you everyone for the warm welcome. It's good to be back!

We start our first update on PC with the a notice for players using Analogue Pocket.

---

We've been getting an increasing number of bug reports regarding this issue and thought it a good idea to put this message out.

Players of Pokémon Prism on Analogue Pocket have been reporting save corruption issues. We have investigated and found the problem is with the Pocket itself, as software emulators and official hardware are unaffected. This issue can cause irreversible data loss and damage up to and including the loss of all Pokémon in your PC Box. This corruption remains even if you use the game pak on another console or boot it up in an emulator.

We would therefore advise players on Analogue Pocket to back up their save files immediately or, if playing on carts that cannot be backed up, stop using the console until Analogue issues an update to fix this bug. Official, non-Japanese Pokémon games do not appear to be affected, however, this may affect other Pokémon game mods like Prism.

Analogue should be able to fix this issue with an update to the console. We'll let you guys know when or if that happens and when it is safe to play Prism on the console again. Hopefully soon.

Huh. Seems I took a wrong turning somewhere…?



(Little teaser for you all!)

 

[Kip]

Hi guys! We've seen a few bug reports coming from users who have purchased Pokémon Prism on a physical cartridge, and wanted to issue some advice for anyone thinking of purchasing. In short: please be careful.

RainbowDevs does not and will never sell Prism on a Game Boy cartridge/Game Pak, and companies that do are doing so without our consent or endorsement. Prism is available for free to download online, and money from cart sales will go to these companies and not to us.

We can't guarantee that the carts will be bug-free or up-to-date, and they may exhibit problems that have since been fixed or behaviour that is not present at all in-game. This is up to and including softlocks and save data loss. We will not be issuing updates to fix bugs on cartridges that have been produced without our consent.

If you'd like to play Prism on real hardware, you absolutely can! You can look at flash carts like the Everdrive or others. These are Game Paks with an SD-card slot that allow you to load and update ROMs from your computer. There are also other, third-party consoles that allow you to insert an SD-card directly into the device to play Prism that way.

Pokémon Prism releases are open source, meaning that anyone can do anything they want with the code. We have no recourse to stop the game being produced or purchased on a physical Game Pak, cartridge or preloaded onto gaming hardware. We are not asking for anyone to report these products to us or anyone else. We are also not specifically advising against purchase. This post is to just inform prospective buyers of the risks involved when purchasing these products so they are able to make an informed choice.

Feel free to ask any questions. And, as always, thank you for playing!

Any plans to add some of the features of polished crystal? such as having abilities, unlimited tms and natures, etc... for examples?

Would be cool to have such features in this hack. I also recommend you have a place where anyone can download it so cease and desist will have a hard time doing damage again,

 

[Corveone]

Does anyone know if there's a way to turn off EV/DV gain? I remember my team stats being a bit OP in the late game and I'd like to avoid that if possible.

Prism already has Abilities and unlimited TMs, even in the older release.

Sweet, why isn't that advertised in it I wonder.

Oh, that is an excellent point. I suppose we've been playing the game for so long and the newer games with this stuff already there I forgot that it wasn't in the vanilla games! Thanks for this, I will update the OP.

We've adjusted a lot of the post-game levels to present more of a challenge, so hopefully this shouldn't be necessary. Feedback is always appreciated, however!
