Hi, I have some trouble on a MV2-01 slot (I think mainly from a bad trace, because it came gradually and flex the board could solve the issue before)
when I perform the Palette RAM test the result is
Adress 400020
actual 0002 ("indirect" D1 stuck high)
expected 0000
I'm sure the problem does not come from the RAM because I swapped them and the error remain the same.
If I remove the lowest RAM the error become
Adress 400000 (the beginning of the Palette bank adress area)
actual 00FD ("indirect" D1 stuck low)
expected 0000
of course the expected should be 00FF in reality as lowest RAM was removed and pulled high by other IC, so there is something related to D1 but through another chip (NEO-B0 ? it's a first gen 2 slot).
It could be also the G0
Any idea welcome.
