Includes: * MARIA - increased accuracy of cycle timing, games now run at close to intended speed (One on One, Tower Toppler, Summer Games, KLAX, Karateka, etc). * Timers now properly take into consideration cycles generated via MARIA and during WSYNC. * POKEY - implemented RANDOM (read) and SKCTLS (write), Ballblazer now plays all sounds. * MARIA cycle stealing and WSYNC now enabled by default. * Database - flags=0 (enable both), flags=1 (disable MARIA cycle stealing), flags=2 (disable WSYNC), flags=3 (disable both). * Database - Ability to adjust HBLANK period prior to DMA (Ballblazer hack), lightgun crosshair x/y offset (frontend) and whether cart supports dual analog (Robotron, frontend). * Increased compatibility for PAL games (Ballblazer, Commando, and Food Fight). * Compatibility and graphical glitches fixed in various games (including Ballblazer, Kung Fu Master, Midnight Mutants, Summer Games, Plutos). * States now save/restore state of RIOT timers for games using them. * Updated palette (Underball). Missing: * Lightgun support * High Score Cartridge support
