I installed MAMECE 8.1 (extra large build) on my Casio E-125 and downloaded pac man and galaxian. When I run the MAMECE program, it doesn't show any games available. I set up the directory structure as suggested, with MAMECE, MAMECE\ROMS and MAMECE\SAMPLES. I have not unzipped the roms. Do I need to also download a SAMPLE file too? Please help. How do I get MAMECE to show which roms I have on my device?
