I did a brief search online but couldn’t find exactly what I’m looking for. Basically I’m looking for versions where you can, say, play FireRed but are able to catch all 150 Pokémon with all of the trading/“choose on of these fossils”/version exclusives eliminated, so that you can complete the Pokédex yourself on one save file.
So far I’ve found a bunch of cool looking ROMs that are total fan made games with new regions, able to catch all 900 Pokémon or whatever, which look awesome and I’m gonna try them at some point, but atm I basically wanna live out my childhood dream of “catching them all” which I could never do as a kid because I didn’t have multiple friends with game boys and Pokémon and link cables and all that stuff.
QOL adds are a bonus but what I’m looking for is pretty basic, surprised I couldn’t find it.
Is there something that works like a Gameshark but for ROMs? That's what I used to cheat my way to all 151 back in the olden days.
I think the gameboy/DS emulators at least let you just open up the game's memory directly.
Based on this comment I think I found the website @glimmer_twin was looking for:

VBA supports cheats, I dunno if specifically gameshark codes though. Probably a bunch of emus have support for it, I mean they have complete unfettered access to the memory stack software is executing on since they're emulating hardware. I think retroarch has a dedicated menu exclusively for cheats too, and I found a list of cheats lol
