These commits are part of an unfinished project, called HIRES background. The tech behind this is ready and already upstreamed in gsKit, but never used in OPL.

You are ofcourse free to use whatever code you like from my repositories. But why?

This pr was made because i spoke with krah about this repository and related with 240p and we both agreed to add this to open ps2 loader but i left him first deal with 240p resolution then me with this patch, Also when this call: guiStartFrame it´s the same call with the diffrence that it´s thread lock for the gui. The only tech that i saw which is rebased from gsKit is: renderman.c on this pr which i will probablly see this.
