• Added some basic support for Sega Pico, a MegaDrive-based toy.
• 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 bin_to_cso_mp3 tool, based on Exophase's bin_to_iso_ogg. The tool can convert .cue/.bin Sega CD images to .cso/.mp3.
• Greatly improved Sega CD load times.
• Changed how scheduling between 68k and z80 is handled. Improves performance for some games. Credits to Lordus for the idea.
• YM2612 state was not 100% saved, this should be better now.
• Improved renderer performance for shadow/hilight mode.
• Added a hack for YM2612 frequency overflow issue (bleep noises in Shaq Fu, Spider-Man - The Animated Series (intro music), etc.). Credits to Nemesis @ spritesmind forum. Works only sound rate is set to 44kHz.
• Implemented some sprite rendering improvements, as suggested by Exophase. Games with lots of sprites now perform better.
• Added better idle loop detection, based on Lordus' idea again.
• "accurate timing" option removed, as disabling it no longer improves performance.
• "accurate sprites" was removed too, the new sprite code can properly handle sprite priorities in all cases.
• Timers adjusted again.
• Improved .smd detection code.
• ARM: fixed a bug in DrZ80 core, which could cause problems in some rare cases.
• ARM: fixed a problem of occasional clicks on MP3 music start.
• Minor general optimizations and menu improvements.
• Fixed a bug in Sega CD savestate loader, where the game would sometimes crash after load.
• Fixed a crash of games using eeprom (introduced in 1.40b).
• fixed suspend/resume (hopefully for real).
