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.

Tried to re-write a C++ NES Emulator in Rust, now it runs more than 5 times slower (Yes I'm compiling with --release)
I've been following along with a Youtube series about writing a NES emulator in C++. The official Github for the series is here: https://github.com/OneLoneCoder/olcNES.
