ZodTTD has updated his Playstation 1 emulator for the GP2x.

Changes:

– Changed the way ROM support is handled. The following formats are currently supported:
.BIN – This is a RAW format rip of a CD. You can rip these with most tools such as CDRDAO or use a program IsoBuster to convert formats to RAW BIN format.
Note: MagicISO converted ISO’s are not supported, use IsoBuster.
.Z/.table – This is a compressed .BIN image using the tool PocketISO 2.1
.ZNX/.table – This is a compressed .BIN image using the tool PocketISO 2.1. ZNX is the default output of this tool when ripping out musics.
.bz/.index – This is a compressed .BIN image using the tool PocketISO.
– Made PsxCycle default to 1 instead of 2. This affects default performance settings of PsxClock.
– Unai added a Abe’s Oddysee specific fix to the graphics engine. Use this fix for Ae’s Oddysee only, otherwise you may see graphical glitches. It can be turned on and off via the menu.
– Unai added Frame Limiting to the graphics engine. It’s on by default and limits the Vsync to NTSC/PAL rates. It can be turned on and off via the menu.
– GCC compiler optimizations were made to improve performance.
– Changes to the dynarec to handle load delays. This may change compatibility for better or worse, to be determined. Also last minute fix for handling shift instructions.
