Please forgive me, most probaply this issue was discussed again but I couldn't find any answer.
I have working ROMs in MAME UI but they don't appear in the MAME list in GameEx.
I have try disabling the "Verify ROMs" but still the same (and the rest of filters set to true).
What is the procedure to check those "not showing" MAME ROMs?
(An example of not showing ROM is the Q-BERT)
