PicoDrive 1.50 released

[Mooney]

Sega Genesis and CD emulator for PSP

* 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 if 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.

* 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).
