I’m currently using the 1.0.0.3 build of retroarch, as well as the latest nightly build for mupen64. I am unable to play n64 roms using the previously mentioned tools. Every other core works more or less. My system specs are:
Processor Intel® Core™ i7-3520M CPU @ 2.90GHz Video Card Intel® HD Graphics 4000 Memory 8.1 GB Operating System Microsoft Windows 7 Ultimate Edition Service Pack 1 (build 7601), 64-bit
