@periodiclogic said in lr-mame2003, Rewind Functionality, and Segmentation Faults?:
Emulation Station would briefly load the ROM, and then kick me right back out. The error log, whether detailed or not, only showed of relevance a Segmentation Fault in runcommand.sh.
That does seem like an emulator bug. Could you please post this report & the log as a new issue in the mame2003 github repository?
