Previously working setup:
JPN A Board (tested and working)
JPN B Board - suicided Street Fighter Zero, Rev 7 (unknown if now working as jumpers have been set for the multi and ROMS removed)
Darksoft CPS2 Multi, purchased in April 2019 from saveyourgames.it (old version, long pins, key writing wires soldered successfully)
When the multi was working, I had encrypted ROMs on the SD card and everything was functioning perfectly. I also had the CPS1 conversions running. Now, when selecting encrypted games I get the same issue described here:
https://www.arcade-projects.com/threads/cps2-b-board-does-not-boot.1577/ and the CPS1 games load and play, but have no sound.
I have tried unencrypted roms using the unencrypted rollup pack - none of these work, usually black screen, sometimes deep red. When trying these games, they flash OK but do not start. I disconnected the key writing wires by lifting the connector to CN9. The wires are still soldered at the other end to the multi. I did not fancy removing those!
I have copied the Testing folders for troubleshooting and ran both of those - no errors.
I have shorted EXC5 again, reformatted the SD card and copied both encrypted and unencrypted ROM sets and tried both again - still not working and presenting the same problem described above.
I have purchased another CPS2 setup to troubleshoot, which is:
Newly acquired setup:
JPN A Board (tested and working)
JPN B Board - Conversion to Aliens Vs Predator, Rev 4 (tested and working)
As it's a Rev 4 board it doesn't have the connector. The jumpers are configured for the AVP conversion - No battery.
What would you suggest I try next?
Thanks in advance, I really hope I can get this going again.
