Speaking of getting "new" ROMs to work in MAME, I still for the life of me cannot get the Buckrogers/zoom909 ROMs to work with every MAME I have used (from 117 to 120). This includes a version of MAME32FX as well. They seem to show missing files (often with a .cpu ending) but I am damn sure I have the parent ROM for this. EG I have buckrog.zip and zoom909.zip. Any ideas?
