crazy ndure its like portage rootage
but only what it takes is porting
unfied toolchain uclinuxpsp to unfied psvitatoolchain
with buildroot busybox1.7 vmlinux.bin.gz
psvitapatches instead of psppatches
and ported danzell uclinux bootloader
with osk mousemd and nanowindows
and maybe u can still compile more
with ur unfied toolchain buildroot
and all of the info is findable online
