Has anyone ever encountered this? The gist of the text is: "The write operation did not finish normally. Please power off and check the system."
The first and second steps of flashing MB-2011 BIOS completes successfully, but then the third step is interrupted about halfway through with this. I've tried flashing the regular 2.0 BIOS but it won't even load--color bars display on screen and then it restarts.
I'm using a 27C160 with the bin file doubled up since I don't have any 27C800s, if that makes a difference. The graphic issue is a separate problem, I believe, and something I'll work on after solving this.
Solved the above by cleaning the EPROM socket; writing the BIOS completes successfully, but now when I try to boot a bootleg I get System Error 000542. Google doesn't seem to have any info about this error, and looking at the mame taitogn.cpp isn't helpful either.
