I've been banned from everything so this is the only way to get the word out about this, so here we go!
I bought the Data Frog SF2000 handheld retro game console (it looks like a Super Nintendo controller).
It's been widely reported that the SNES and GBA emulators are laggy and the games are basically unplayable. However, all you have to do is change your "TV System" in settings from NTSC to PAL. This fixes the SNES lag completely. The GBA still feels slightly off, but is now playable.
Changing the TV System from NTSC to PAL doesn't affect the other emulators, so you can just leave your settings on PAL and everything will run fine.
For those who don't know, NTSC and PAL settings refer to North American and European TV refresh rates, so game consoles had to be tweaked to work correctly in different regions.
For whatever reason, all emulators can detect and adjust to NTSC or PAL aside from the SNES and GBA emulators, which have to be manually set to PAL or they lag.
