Do not worry my friend!! You’re not the only one.
As of 5 mins ago, I’ve been chatting with guu. It’s being worked on, and will hopefully be included in the 0.5 official release and/or the update file!
I say to use the 0.5 version, simply because most of which was implemented in my DEOT was the inspirational base for what people have come together and worked out; AND then applied to 0.5. The main bonus is that it will be updateable, and more future proof. That is, if you like fiddling. You just won’t have the DEOT theme. (Yet! Wink wink ;))
If you just want one OS to keep on there to just play games, and don’t care about development, the DEOT custom one will be fine.
Meantime, if you want to try installing mupen on your 0.5 image, check this out:
