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.
