Best compiler to write .nes cartridge ROMs for testing my own emulator?
If you really want to use it, I have a bad 65816 assembler at https://github.com/raddad772/jsmoo/blob/main/component/cpu/wdc65816/wdc65816_assembler.js . Just don’t switch it to 65816 mode and it should produce compatible code. I wrote it as a pile of hacks on top of each other and you still need to add an iNES header.

Trouble with GB Joypad Input
If you want to really verify your CPU, check out https://github.com/raddad772/jsmoo/tree/b3807b55f03cdad2191810b2a770781d73c41870/misc/tests/GeneratedTests/sm83 , a set of 1000 tests per opcode, cycle by cycle, including read and write bus activity, in JSON format. It’s a bit of work to integrate them but there’s no better CPU test. Also you can generate more if you want to by using the code generation portion of the codebase. The only thing it doesn’t really test well is IRQ/halt stuff. It’s pretty common for folks to pass Blargg and still have things uncovered here. Usually things Blargg can’t test, or symmetric errors (flag both set and tested wrong), or corner cases Blargg didn’t think of.

IronBoy: High accuracy GameBoy emulator written in Rust and available in the browser via WASM
Hey, since bro was kind enough to provide the source repo, you should probably post problems / feature requests to https://github.com/nicolas-siplis/IronBoy/issues instead of here.
- feboy (DMG GB emulator) now has full audio support! Special thanks to /u/KingWallmo for working on it the last couple months. Suggestions on what feature to add next?
- Open source project to get involved in as an audio developer

Gameboy Doctor: debug and fix your gameboy emulator
Hey there! I've been working on a Game Boy emulator since last year and found the GameRoy project, which translated the PPU's logic from SameBoy, the (AFAIK) most accurate GB emulator around. I basically copied the PPU logic into my emulator and replaced the "state" property (an integer) with enums for some extra clarity.
