Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.
- Starting Game Boy emulator, need a little insight
- Snes, Nes, GameBoy and A26 emulator.

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.
