- Added a new graphics engine in 256 color mode. It should be much faster in areas that don't use mode 7, but lacks a lot of features such as windowing, mosaic, and sprite priorities so it is disabled by default. It can be enabled by pressing 8 during gameplay. (~40-100% faster)
- Optimised Mode 7 in 256 color mode
- Implemented dual windowing to color window clipping
- Fixed several color window clipping bugs
- Added full resolution screenshot capture in 640x480x65536 mode To activate while in that mode, hold backspace and press F1
