Hi UKrobm
Thank you for your interest in the project.
Error code -1 usually indicates you have supplied an incompatible ROM file. Does the ROM file you have work with MAME?
Can you try a different ROM file?
Let me know how you get on.
Thanks,
Thanks for the quick reply, I'll check that.
You were right. I must have connected the board up wrong when I scanned the eproms. It's working fine now. Thanks again! :)
Great news!
Thanks for letting me know and supporting the project.
Enjoy!
