RetroCopy v0.300b Changelog:
-Added cycle accurate NES emulation. Not perfect yet but most USA mappers have been added and most USA games work. Import your NES games to the .GAME format the same way you do for the SMS games.
-Added 3D virtual game room with dynamic pixel lighting and 3D sound. Select a TV to play on and load a game. Automatic detection of modern cards should still allow old 3D cards to run RetroCopy
-Allowed multiple systems to be run at same time which required reworking the main emulator thread
-Reduced EXE size by removing some unused visual assets from RetroCopy like the old 2D TV
-Added new camera class that has a lot more functionality and improved view of the 3D world
-Fixed bug in sound core which forced all cores to use same output buffer resulting in distortion with multiple games
-Moved sound to its own thread to offload 3D sound and general audio processing from the emulator thread
-Fixed bug in SMSVDP v1 where SMSVDP2 video modes were allowed
-Fixed bug in SMSVDP v1 with the last 4 sprites only being zoomed vertically
-Added .3DS loader and got rid of the milkshape 3d loader because the model format breaks often. Now specular lighting and other effects are better
-Improved movement in 3D world by increasing speed and ensuring framerate has no effect on precision. Also simulated popular FPS games like CounterStrike with left shift allowing slower movement in the 3D world
-Fixed bug which allowed you to zoom into the middle of the 3D game boxes
-Fixed bug in audio not being completed reversed when rewinding, Sound quality is now much improved when rewinding
-Added mipmaps to 3D modes which generally increases quality. If you have a card capable of Anisotropic filtering it will be enabled by default which further increases quality
-Reworked ROM browsing/loading interface. Now you have to select a TV before the ROM browser appears. It is now also shown transparently over the virtual gameroom
