[Picodrive2x v1.32 - Genesis and Mega CD Emulator for GP2X:]

[wraggster]

Notaz released a new version of his Genesis and Mega CD Emulator for GP2X:

There is not much new stuff:

* New software pixel-averaging scaler for games using "32 column" display mode (256x224), plus additional vertical scaling option.
* New ability to swap ISO images while the game is running (needed for Night Trap, for example).
* Added RAM cart emulation.


... but loads of bugfixes:

* Fixed DMA timing emulation (caused lock-ups for some genesis games).
* Idle loop detection was picking up wrong code and causing glitches, fixed.
* The ym2612 code on 940 now can handle multiple updates per frame (fixes Thunger Force III "seiren" level drums for example).
* Memory handlers were ignoring some writes to PSG chip, fixed (missing sounds in Popful Mail, Silpheed).
* Improved z80 timing, should fix some sound problems.
* Fixed a bug with sram register (fixes Phantasy Star 4).
* ROM loader was incorrectly identifying some ROMs as invalid. Fixed.
* Added code for PRG ram write protection register (Dungeon Explorer).
* The memory mode register change in 1.31 was unsafe and caused some glitches in AH-3 Thunderstrike. Fixed.
* Fixed a file descriptor leak.
* Updated documentation, added Gmenu2x manual.

Chilly willy at maxconsole has said that he should write a Sega CD emulator for the psp from scratch. that would be something very cool :D

perhaps it could blow us away like gpSP did a year ago ;)

This emulator only worked on high powered pc's it was amazing how it appeared on gp2x.

The gp2x has dual core that's why it was made for it othwise it won't able to handle it.

The psp doesn't have dual core it won't able to handle one processor won't do the job, this will never appear on psp.
