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 !
