Gngeo2x is a NeoGeo Emulator for the GP2x, with assembler Z80 core and graphics dumper. It runs most games fullspeed with sound and features save states! This is the developmental build of the emulator and therefor may be unstable.

The dual CPU bug should be fixed in this version.

Installation:
– You should have an unzipped psx4gp2x directory where this readme.txt is located.
1. Copy the REQUIRED (not included) psx BIOS file scph1001.bin to the same directory that psx4gp2x’s gpe file is located (./psxgp2x)
2. Copy your ISO/BIN files and/or PocketISO 2.0+ compressed Z/TABLE files over to a directory such as the roms directory in ./psxgp2x
3. Copy the ./psx4gp2x directory to your GP2X storage media
4. Run psx4gp2x_[build_date].gpe

Controls:
GP2X – PSX
STICK – THUMB PAD
A/B/X/Y – CORRESPONDING CIRCLE/SQUARE/TRIANGLE/X BUTTONS
L TRIGGER – L1
R TRIGGER – R1
L TRIGGER+PUSH – L2
R TRIGGER+PUSH – R2

R TRIGGER+VOL-DOWN – PSX CLOCK DOWN
R TRIGGER+VOL-UP – PSX CLOCK UP

Tips for getting maximum performance:
– Using interlace 1+ setting gives more performance at the cost of blockier looking graphics from upscaling
– Turning sound off may give a slight performance increase
– Use your best overclock and use ram timings on if possible
– Be sure to find the best (working) PSX CLOCK setting. Usually a lower PSX CLOCK setting that keeps VSync less than 130 while keeping the highest framerate (FPS) is recommended.
– If you feel like tweaking timings more, change PSX CYCLE from 2 to a different value first. BUT IN ORDER FOR THIS OPTION TO BE RECOGINZED, YOU MUST RELOAD THE GAME FROM THE INGAME LOADGAME OPTION EACH TIME YOU WANT IT SET TO THE NEW VALUE!
– Once the PSX CYCLE has been successfully changed, edit the PSX CLOCK timings. Usually PSX CYCLE 1 to 4, maybe 5, is best.

Tips for compatibility with games that freeze or won’t load:
– Change the PSX CYCLE to 1 and change PSX CLOCK to a number between 80 and 104. Do this as soon as the game inits/loads up and then RELOAD THE GAME FROM THE INGAME MENU with these new settings in place.
