Ok to be honest i have no idea what the Frame Buffer is like on TR64 OGL because it actually has quite a few issues with textures and a white reacuring backgound that prevents any real time testing not to mention Un-Playable (See TR64 Images) and save state
I have also attached 2 images from Jabos plugin also and a save but don't be fo0led when you load it, the save state loads a good image but it was saved using Jabos plug and not TR64 so it is wrong to as what should be seen when you press the Pause Screen (start) it is actually a previous place where i last used Jabos Pause Screen. (Ice thinks this fact is interesting) lol
