- Completely restarted and finished Genital68K; removed Starscream
- Wrote a very good, custom debugger
- Messages now display in the correct position if a resolution other than 320x200 is chosen at start up
- Rewrote Mode X code. It's now much, much faster. Big thanks to Kuwanger for his input

- Rewrote address space access handlers in assembly to take advantage of Genital68K resulting in a major speed boost
- Major VDP status register fix regarding VB, HB, and DMA bits (fixes speed problems in Granada, Altered Beast, After Burner 2, Turbo Outrun, Ranger-X, Arcus Odyssey, etc.)
- DMA flag now always indicates ready
- Fixed up interlace 2 odd/even flag kludge
- Added VDP PAL flag emulation
- FIFO flags now always indicate empty
