Hey BaFelton, I have a couple suggestions. The whole Dingoo/Gemei family is confusing but there's some things that should be pointed out. The A380/A320E are the same machines, just rebranded, so maybe those should be grouped together. The Dingoo A330 originally had a PSP form factor, then they took the Gemei A330 and rebranded it as the Dingoo A330 so maybe those two should be grouped as well.
It's not really true, gemei a330 and dingoo a330 with the same form factor are same device (arm cpu).
Dingoo a330 (psp form factor) and dingoo a320 are almost same device too (and mips cpu).
About dingoo a320e and dingoo a380 the emulators are differents, pretty hard to explain on the document that one of these can run mame, scummvm and atari 2600... and not the other one. Btw we don't know if these handhelds are the same, hardware have somes differences, maybe dingoo tech broke comptatibility. For the moment, we can't add new emulators for try the a380 one to the a320e (no way to acces the .dge files)
