It will allow you to easily port GameMaker Studio v8.1 games to the Sony PlayStation Portable (PSP) video gaming console.

Known issues

This is quite buggy mostly due to using Karoshi (a PSP MINI put out by yoyogames back in 2011) as the runner for the game and adapting a early GMStudio Compiler to build files for it.

The "runner" was never released publicly as an GM export module, and is basically was always in beta, before being abandoned in favour of the PSVita version. don't expect stuff to work well.
