Hey all,
I recently acquired AES unit (rev 3-6)
It has graphical issues that I'm finding hard(impossible) to diagnose.
1. Neogeo animated label doesn't display
2. sakura petals do not display prior or during story.
3. backgrounds/characters are duplicated up the screen with various artefacts.
Health bar/ timer and some other graphics display no problems.
Audio has no problems at all.
I've installed the diag bios but it reports no faults however i cannot test z80 since I dont have a cart to sacrifice.
Tested the data lines and cannot find any breaks.
The board is almost in mint condition just a pity about the fault.
