Can't that unit be revived? I don't see why risking a donated unit would be a problem though
best he could tell one of the customs blew, so no
and yes, he was finding people wanting $1000 for a system / game, even the more common ones, and that was 2 years ago.
the strange thing is the tests he did manage to do confirmed MAME's sprite size behavior, which the Speedy D pre-title attract demo disagrees with. I do wonder if there might be some bad bits in ROM.
