When the PPU Fast Mode core option is set to OFF, the output resolution is always 512x448 instead of the expected 256x224 which most games use. This ruins the use of almost any CRT shaders as the output is incorrect.
When the PPU Fast Mode core option is set to ON this does not occur and the resolution is output correctly at 256x224 for most games and 512x448 for those specific games that use it.
