When I choose the IBM PC/AT 5170 rom or one of its clones, MAMEUI 0.185 crash. It crash when I just select it, I don't even double click on the rom set.
It also happens with CBM 8296 rom set (or any of its clones).
It's very strange... I try on a clean MameUI installation (without any ini or other config file).
Anybody can help?
