Here's a version of Gameblabla's Oswan for OpenDingux.
I know the Dingoo is long dead but i wanted to give it a try anyway
For those who don't know, it's a Wonderswan emulator based on Oswan with some improvements from Mednafen & others.
In theory, it should work on the Dingoo A320 and the Game Gadget.
It should work on the Dingoo A380 too but it does not take advantage of the bigger screen.
I don't actually own a Dingoo (only a zero) so let me know if this works on your Dingoo.DownloadEDIT:
