@barleyguy Hi, I did several tests, I also reinstalled recalbox from 0 on the MicroSD and these are my findings on Recalbox 9.1 on Retroflag GPI Case 2W with Raspberry 0 2W with copper heatsink:
- No overclocking
- Installing from scratch, if I insert only a couple of Dreamcast games, flycast "seems" to go quite well, it only crashed once and in that case you have to remove the cartridge forcibly because you can't get out anymore
- I have loaded the BIOS and roms of all the other platforms that interest me for a total of around 27k roms, I know that there are a lot of them and I have warnings from the Recalbox system that I shouldn't exceed 10k
- PSX and Nintendo64 work very well for me (the latter with the default GLIDEN64 emulator whose buttons I still don't understand and they are not explained on the Recalbox website)
- My Amstrad GX4000 works badly (slow and bad audio), Game and Watch don't work
As for the Dreamcast, I tried to monitor the CPU temperature and it doesn't exceed 65 degrees when it freezes, the throttling happens around 80 so I don't think it's a temperature problem, so it seems that when you overload Recalbox with so many roms it no longer works good, but that's just my hypothesis. I'm trying with the Reicast emulator but there too, it seems to start better but then there is no mapping of the keys on the guides and I don't know how to adjust any settings to improve performances
