Improved bin_to_cso_mp3 tool, it should no longer complain about missing lame.exe even if it's in working dir. fixed suspend/resume (hopefully for real). Fixed a crash of games using eeprom (introduced in 1.40b). Fixed a bug in Sega CD savestate loader, where the game would sometimes crash after load. Minor general optimizations and menu improvements. 'accurate sprites' was removed too, the new sprite code can properly handle sprite priorities in all cases. 'accurate timing' option removed, as disabling it no longer improves performance. Added better idle loop detection, based on Lordus' idea again. Games with lots of sprites now perform better. Implemented some sprite rendering improvements, as suggested by Exophase. Works only if sound rate is set to 44kHz. Added a hack for YM2612 frequency overflow issue (bleep noises in Shaq Fu, Spider-Man - The Animated Series (intro music), etc.). Improved renderer performance for shadow/hilight mode. YM2612 state was not 100% saved, this should be better now. Changed how scheduling between 68k and z80 is handled.

Added bin_to_cso_mp3 tool, based on Exophase's bin_to_iso_ogg. Added proper support for cue/bin images, including cdda playback.cue sheets with iso/cso/mp3/wav files listed in them are now supported too (but 44kHz restriction still applies). Added some basic support for Sega Pico, a MegaDrive-based toy.
