- VDP2: Honor access cycles and VRAM bank allocations to restrict pattern name and character pattern accesses. Fixes garbage graphics in Panzer Dragoon Saga, Sonic 3D Blast and Street Fighter Alpha/Zero 2
- VDP2: Invert back screen color calculation ratio. Fixes black background on Sakura Taisen FMVs
- VDP2: Move existing VCounter into VDP2 VCNT register. Fixes Assault Suit Leynos 2 freeze when going in-game and King of Fighters '95 not booting

Обновился эмулятор Atari ST - Hatari.

Emulation improvements:
- 030+MMU:
 - Workaround to correct prefetch data after bus errors
