hi,
seems that dash can only be launched from C, E or F root.
If u use evox (for example) and want to use dash2GAM as an app, put dash2GAM.exe to root directory and try this
Item "dash2GAM","e:\dash2GAM.xbe"
i don't know if hex editing in that way is such a good idea, dash 2GAM use xtf not xft, i use fonts exploits too and i got a f0nts repertory with original xbox.xtf and xbox book.xtf inside
try to hex editing dash2gam.xbe and change fonts to f0nts (zero not O )
