This one came from the same lot of faulty PCBs (seven in total) as the previously repaired Growl.For the uninitiated, Cadash is an action game with some RPG elements.

Board was in good shape (it has also additional hardware for multi-link game) .

When powered on I got this screen:

Cadash_issue

There was a clear problem with main code execution so I dumped the four program ROMs and none of them matched the ones in MAME.I ran these dumped ROMs in MAME and I got a similar error (different memory address due not perfect emulation of 68000 core, I guess):

MAME_cadash_error

This was enough to lead me to reprogram the four program ROMs from cadash World set into 27C010 devices.And this was the winning move which fixed the board.
