Posted: Sat Aug 20, 2022 5:41 pm
Two new test roms for emulators, first one - not deeps checks of rarely emulated stuff, second - dma speed checker:
some notes:
all delays tests not check delay values, only for delay exists or not.
sprites over 64 checks how this sprites are work (collision flag used to detect if glitched sprite created).
sprites collision flag checks for 1) time when it set only by vcounter; 2) if sprites being on screen.
vcounter corruption test not always work on hardware, you can find other special test for this.
tests was checked on md2 pal and ntsc and md1 ntsc.
