Exploring the Gameboy Memory Bank Controller (2020)
Game Boy disassembler: https://github.com/mattcurrie/mgbdis
You can compile the ROM's back with rgbds: https://github.com/gbdev/rgbds
Here you can see how bank switching works.

My GB studio said a file was missing so I reinstalled GB studio but now none of my projects open
You can get images out of it. Find the image locations in the ROM with a tool like YY-CHR, then annotate that location in the disassembler (like https://github.com/mattcurrie/mgbdis).

Ghidra - Editing Gameboy ROM for Analogue Pocket
I didn't use Ghidra, I only used mgbdis to create a disassembly. Patched it and then reassemble it.

ROM Hacking Guide
You make it sound like there's a machine you can put a Game Boy ROM into and get out a disassembly, which is kinda true (https://github.com/mattcurrie/mgbdis) but it doesn't automatically split out data blocks or anything like that - it just tries to crawl the ROM and disassemble any code it can find. It's certainly not "effectively no additional work" than making targeted alterations to the binary and documenting your work.
And that's before you get to platforms where most if not all games are written in C - I question whether a mere disassembly of a game like Pokemon Emerald would even be useful to anyone, whereas the pokeemerald decompilation (https://github.com/pret/pokeemerald) is clearly useful but was a heck of a lot more work to produce.
> That's a hurdle, but not an insurmountable one... unless the system didn't even support banking. (Are there any systems that didn't?)
Depends what you mean by "support". I don't think any system has a built-in mapper - they just assign a chunk of memory space to the cartridge bus, and if your game is larger than that chunk of memory space you include a mapper on the cartridge. Nintendo provided standard mappers for machines like the NES and Game Boy because it's very hard to include a substantial game in the wedge of memory space you get on the processors in those machines, whereas only one game on the Genesis/Megadrive needed one.

Since the subreddit is going down tomorrow, here's an update on inserting custom player graphics with the Universal Pokemon Randomizer ZX
It has been a while since last, but that's because of compression algorithms and memory allocation issues, which had to be taken care of before writing the front/back images in Gen I and II. Big thanks to FuSoYa, RGME, and the decomp team, who provided the tools and guides which made this possible.

[OC] Pokemon Adventures:The previous generation chapter 48
Ash didn't catch charmander. Charmander belonged to a different trainer who abandoned charmander. Ash came along and saved charmander and adopted him.. And it's still traded only. The rule was created specifically for the video games to prevent you from getting traded a really powerful pokemon from a friend and steamrolling the game. Whether or not the badge rule applies is based on whether or not the trainer I'd matches the pokemon's trainer ID. The game has been completely decompiled. You can literally check the source code and see the function yourself.

[Gen 1 - R/B/Y] Celadon City Game Corner RNG "manipulation'
I tried to look into this a while back, I've been curious about what actually determines these odds. There's a disassembly of gen 1 to dig through. It looks like the SevenAndBarMode referenced here is the super lucky state, and AllowMatches and AllowSevenAndBarMatches looks like they're playing with odds. Can't fully make sense of how it works or how these get initialized.

Original Pokemon RGBY export all audio and SFX as midi
I initially wanted to export all the original audio from the games rom as midi files. Fortunately my google-fu lead me to this a post on romhacking in 2014 where the PokeRed Poject rom audio has been disassembled to asm. Going through the list I noticed not all the audio is properly titled and some songs could be missing for example MtMoon and Cerulean city is missing.

Help required. [Pokemon Red]
Start by installing the pokered disassembly. You can then edit the game's data and code with any text editor. You can adjust the base exp given by a Pokemon by editing their base stats in data/pokemon/base_stats/. For more complex modifications you can adjust the experience gain formula in engine/battle/experience.asm.

Pokémon Riddle #39
Is the Pokemon Red's source code a reputable source? In the game, struggle has always been defined as a move along side all the other moves in every generation.
What are some alternatives?
