I must be the only one in the forums who has ever experienced this issue. Great.
I don't know what I'm doing wrong. Using RA and MAME. In the pause menu, if I select either save state, or load state, the pause menu goes away and you see your game frozen. No sound, no input response. Only way to get out of it is to go back to the pause menu and exit game. I'm rather stumped on this. I've set up save state paths and hotkeys and within MAME and RA I can save state that way, it only freezes if I try through the bigbox pause menu.
