I modified rxTools' source by ripping it all, replacing it with Pasta's source/include/stubs, and then modified the makefile to point to them. I'm doubtful it would be as simple as interchanging the files included and where the makefile points, but it's worth a try. It'd be a hob-job, but rxTools is made to run via the WebKit entry-point, so it'd be pretty cool if it did boot through Roxas' payload HTML.
If this DOES somehow magically work, would it mean we could run pasta from emunand?
