Installed on the RG34xxSP. My biggest issue was a common one. Correct bios, Correct bios placement and bad roms. Was able to run, Naomi, Atomiswave, CDI, PSP. Although not all Naomi games launched. Still can't get Daphne to work. I don't really need it but its always such a pain it becomes a point of pride. I also have the miyoo flip with Surwish. Daphane works but no CDI. Also the interface looks like l made it on a windows 98 using clip art. Otherwise it's the same. L prefer Rocknix. The other issue is easy to a access the retroarch files, etc. With rocknix you can't just plug the sd card into a windows device but with Surwish you can. I am guessing I'm not talking to noobies so you already know more then one way to access the files. If not ask here or Google. FYI. I don't know this dude or get paid but if you have the flip a guy named xs4all4me on Re dit came up with a fix for the stock os that runs ES and it's on Par with Surwish and with help could easily be the best. If l knew how ld help him.
