While I was browsing the Nintendo GBA forums, I stumbled upon this, realized that this also includes emulators and such allowing me to play quite a lot of games. However, I really don't know much about anything about dingoo's or gemei's. So could someone mind telling me what this is? (I know there are multiple models of dingoo's and gemei, which is is the best and decently priced one?) And where I can purchase one?
