An experimental mod of NooDS that makes use of an upcoming version of Retroflow Launcher to launch Nintendo DS games directly, on the vita. Everytime you launch a DS game from Retroflow (upcoming release) it generates a file "retroflow.ini" in the data folder of NooDS, with the contents of: "ndsPath=ux0:(your rom location)/brain_age.nds (new line, empty)" Without quotes and the stuff in brackets you can figure it out. It doesn't have to be brain_age, that's just an example.
Manually built in VitaSDK to the current version of NooDS at time of writing. For some reason the icon and background don't display properly, but the app does work.
