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.

Building a Frankenstein 64
Nice work and thanks for the writeup. Ted Fried has a variety of microsequencer based CPU cores based on FPGA (and ARM) and I think they are quite good.

Show HN: Tenebra game PC port of popular Commodore 64 game
At that point you might as well go MCL64 Teensy replica https://microcorelabs.wordpress.com/2021/04/19/mcl64-worlds-...
"comparing the Super CPU accelerated to 20Mhz and the MCL64 in its accelerated mode, the MCL64 is roughly 2X faster than the Super CPU"
