We tried to test some old Famiclone console with blargg's tests...

Most of tests FAILED at #2 stage or some later...

WHY GAMES LOOKS ALMOST THE SAME? )))
PS, here some debug monitor for FC, reworked from blarrg's libraries. Damn NMI timings, looks like some code running out of time amount for NMI stuff... Even if VBLANK waiting is used before any PPU operation, it makes many glitches on screen. ;(( What is wrong with that?
