Metal Slader Glory repro [solved]

Post by decoder_82 » Tue Aug 04, 2020 9:52 am

Hello everyone,

I am trying to build a translated repro of Metal Slader Glory.

As donor I am using Gun Sight.

Here what I have done so far in terms of wiring.

CHR - 27C040 Chip
=================
socket 1 to A17
socket 2 to A18
Socket 24 to A16
Socket 30 Unconnected (no A19 on 27C040)
Socket 31 to CE

PRG -27C080 Chip
=================
socket 1 to A17
socket 2 to A18
Socket 24 to A16
Socket 30 to A19
Socket 31 to CE

For both PRG and CHR:
- socket 22 is left unconnected
- EPROM 24 is left unconnected

When try the game, music is there but graphics are all messed-up.
All connections have been checked and are OK.
The cart was perfectly working before the mod.

Any idea what I could do to troubleshoot ?

Thank you !
