nes-test-roms's Issues

nestest.log out of date

The version of nestest.log in this repository is several revisions out of date:

  • March 2013 - fixed a bug in the indirect JMP opcode to correctly preview the actual target address (so that address DBB5 now says "JMP ($02FF) = 0300" instead of "JMP ($02FF) = A900")
  • December 2018 - replaced "CYC:x" and "SL:yyy" with "PPU:xxx,yyy" added "CYC:zzz" to indicate the total number of cycles elapsed since reset
  • June 2020 - changed "PPU:xxx,yyy" to "PPU:yyy,xxx" (i.e. show scanline first, then pixel number) and fixed CYC so it starts at 7 (since that's how long it takes to reset)

The latest version can be found here.

StarsSE demo gets stuck

StarsSE demo softlocks in an endless cycles of interrupts/RTI because of the APU frame interrupts. The ROM should properly handle these interrupts or completely inhibit them by writing to 0x4017 with bit 6 (0x40) set.
