Raw Blame History

//TODO hook up newer file ID stuff, think about how to combine it with the disc ID
//TODO change display manager to not require 0xFF alpha channel set on videoproviders. check gdi+ and opengl! this will get us a speedup in some places
//TODO Disc.Structure.Sessions[0].length_aba was 0
//TODO mednafen 0.9.37 changed some disc region detection heuristics. analyze and apply in c# side. also the SCEX id handling changed, maybe simplified
//TODO - ok, think about this. we MUST load a state with the CDC completely intact. no quickly changing discs. thats madness.
//well, I could savestate the disc index and validate the disc collection when loading a state.
//the big problem is, it's completely at odds with the slider-based disc changing model.
//but, maybe it can be reconciled with that model by using the disc ejection to our advantage.
//perhaps moving the slider is meaningless if the disc is ejected--it only affects what disc is inserted when the disc gets inserted!! yeah! this might could save us!
//not exactly user friendly but maybe we can build it from there with a custom UI.. a disk-changer? dunno if that would help
