You mean the black n white pics a few pages back ? I still have that version (backed up). And what's emulated:
- CPU with a few bugs left (stack and and the overflow flag I think), and the only IRQ emulation is NMI (and reset)
- PPU without sprites or bg attribute. All registers emulated with the exception of sprite and scroll related ones. Pixel based renderer (but line-based shouldn't be a problem for simple games).
- APU and input and sprite DMA registers not hooked up (returning open bus: address>>8)
- mappers 0,2,3,9 emulated
SMB without sprite 0 emulation will show its titlescreen, and gets stuck there.
Check NMI emulation, and *every* CPU opcode function. With bugfree NMI and CPU emulation, almost all NROM games should boot, and many will go to demo mode.
