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.

- How is it possible to have CHR ROM of size 0 and yet FCEUX emulator has pattern tables?
- Nestest IRQ interrupt address begins at 0xC004 but in nestest.log it should be 0xC000
-
Any NES CPU tests that I can compare output of my CPU with output of the test?
nestest is the go-to for testing the CPU with logs. Here's the README, ROM, and log.
- My emulator can't write to address 0x8000 because its PRG ROM, but other emulators can?
- Basic CPU only test ROMS
- Confused about page crossing.
- New to developing emulation programs
- What's everyone currently working on?
- What cycles really are?
-
Question about nestest.nes
either check the results left in $02 and $03, or compare an execution log to e.g. this one.

Ask HN: Who Wants to Collaborate?
I'm building an IBM 5150 emulator. Most of it is therefore an 8086 (technically 8088 but no difference for this) emulator. I have it successfully booting the BIOS and running BASIC in ROM (Casette BASIC). I'd like to boot DOS. I could use help with the disk support chips (everything is low level emulation right now) and more CGA graphics modes. It's just a hobby project—I'm not looking to make it performant, just working.
It's written in poor C++ with SDL.

- Anyone else playing with x86? (8086, 80186)

It's at the point where it gets through booting the BIOS and gets to the IBM Casette BASIC (I haven't made much progress on the floppy disk controller to boot DOS). But then all keys get recognized as apostrophes:
