I should make a new thread about the OpenGL stuff as it's a separate project to the custom Game.exe source code.
EDIT: Actually, where would I make a thread about this? Can't find a section that would suit it...
Is there scripts in development?
Anyway, for now:
battleworldrpg.net/hbgames/GLtest2.zip
Load up the game (Uses a custom Game.exe, so warning about that) and talk to the girl, she'll show a picture that will quickly be replaced with an OpenGL frame buffer
That is a very basic OpenGL test, what it does is replace the update for any game picture with the draw call that is inside the custom Game.exe (Or xiGame.exe, I left that one in there :U)
It's VERY rough and basic, at the moment it just draws that triangle with the 3 vertices set to colours that have an alpha of 0.5f.
To repeat; the plan is make it so you can target any game picture as if it's a 3D buffer, draw your crap to it and then display it using picture as you want, from this we can start looking into post-processing shaders (FXAA in RPG Maker, haha) and cool screen-space effects like zoom in with a bilinear filter (At the moment I have it set to nearest neighbour filtering).
