ZodNEO

This is a NEOGEO MVS emulator based on MAME v0.36. It uses its own memory manager for handling large games so that UDMH is not required.

The Cyclone 68000 ASM CPU is used to increase performance substantially for many games but for some games it has been disabled due to incompatibilites.
ZodNEO is also optimised extensively for the Zodiac's ATI graphics chip.

ZodNEO is a spin off of ZodMAME and was split so that memory can be managed differently (hence no need for UDMH), plus other parts of the drivers could be optimised directly for NEOGEO games. 

Installing

Simply Hotsync the ZodNEO-Installer.prc file and this will automatically install the program, make sure your SD card is inserted into Slot1 before doing this.

You'll need the following directory structure on the SD card:
/PALM/Programs/ZodNEO/roms/

Put your 0.36 version NEOGEO ROMS (zipped) into the roms directory on the SD card. They must be 0.36. Don't forget to put the NEOGEO.ZIP BIOS file in there or none of the games will work. You can use clrmamepro (or RomCenter) to create 0.36 roms from the latest versions of MAME. This isn't easy as the NEOGEO ROM structure was changed in MAME 0.80.
