RetroPie newbie here. Got everything all set up and for the most part everything works great. Only problem is one of my sega roms is freezing. I’ve been playing Shining Force for the genesis and I’m 2-3 hours into the game and every time I enter the town Manarina in chapter 2, the whole system freezes up. Sound comes to a halt with a little skip sound, screen goes black and everything becomes unresponsive. Can’t escape out of the rom, need to do a hard reset by plugging/unplugging the Pi. I’m using the latest image from the downloads page here: http://blog.petrockblock.com/retropie/retropie-downloads/download-category/retropie-project/ (i’m at work right now, so I don’t have the exact version number but that’s where I got it from).
I’ve tried overclocking and changing the memory split, but neither helped me. I have plenty of room on my SD card too. Is this as simple as a shitty rom? I haven’t had any other freezes, just on this particular game at the same spot every time (have played other games for a few hours with no issues).
The easiest way is just to copy that one ROM to the other folder. For example If you have one ROM in /home/pi/RetroPie/roms/megadrive-dgen and 50 ROMs in /home/pi/RetroPie/roms/megadrive, you’ll see two “Genesis” options in EmulationStation but one will have just the one game, the other will have all 50.
I’m not sure, but I would bet the save systems between the two emulators are not compatible. But if they are, then yes, you would copy the save file to the correct folder where the other emulator is configured to look for save files. I’m not in front of my Pi, I don’t know the folder locations off the top of my head.
As a general rule in RetroPie, the “default” emulators perform better. So the general consensus is the /megadrive folder emulator works better than the /megadrive-dgen emulator. But both are included because no one emulator is best for every ROM. All emulators have their bugs.
You may be the only person to have found this particular bug, since it happens 3 hours in 🙂
