I tested the DSTT version niu posted above. Works as I assume it should on a Supercard DS-One using the triple loader (meaning Moonshell boots in place of the DSTT firmware) And for the record, it may just be me, but this loader seems a little different and more compatible than the Ysloader. The loading animation is different, and I was able to boot a game I thought was corrupted before (Dragon Quest 9, which wouldn't load properly in ysmenu for some reason). How strange.
Few notes for the DSTT version-
- can't change language to english. I assume some things changed in the hack which makes moonshell corrupt if you attempt to change the language.
- cheats are weird. With my custom cheat datafile in the moonshell folder, it seems to not be able to load any of those cheats, but rather, a pre existing amount that are the same for all games. I see options for things like the ability to use a motion pack (slot 2) to control the game. No game specific cheats.
So, has some flaws. Good start though. I assume the R4 version works great though.
