Hello at all.
I'm here trying to understand a weird problem on my Alpha mission conversion.
I'm trying to use a CHA 42G-2 since i got a spare of this at moment.
This game was originally created on CH42G and not on the -2 version but until now I thought they were almost identical but apparently there is something I don't understand.
Almost everything works but I can't fix this screen and part of the sprite fixes.
I did some experiments on the mame to confirm that this screen is all on the S rom.
Instead of the correct screen I only see the time text and audio, the rest is black.
At moment i'm using J2 and J3 jumpers on cha board, and burned S1 on 1001
Already checked two times crc of S1 and its correct.
