Today I [Wololo] fixed a few issues in the Vita implementation of Half Byte Loader, and got Doom (the PSP port) to run
This is work in progress and the current plan is to release sometime after the US/EU release of the playstation Vita, assuming that doesn't get patched before.
This is HBL (Half-Byte Loader) running Doom (a homebrew) through PS Vita's psp emulator.
EDIT: Amended Homebrew Loader to Half-Byte Loader (thanks DinohScene!)
