PicoDrive by notaz is an excellent Genesis/MegaDrive/SegaCD/32x emulator for Pandora.

Changes:

* Lots of 32X compatibility and accuracy improvements. Most (all?) commercial games are booting now, but some still have issues.
* Fixed some regressions in MegaCD code, like hang in jap BIOS.
* Implemented pause for SMS.
* Updated UI with improvements from PCSX ReARMed.
* Frontend timing has been rewritten, should no longer slowly desync from LCD on pandora.
* Various other things I forgot (it has been several years since last release..)
