AES cartridge: Difference between revisions

Revision as of 05:10, 9 January 2012

A NEO-ZMC2 or PRO-CT0 chip is used to pre-serialize sprite graphics to be output to the cartridge edge. For the PRO-CT0 carts, a NEO-ZMC chip can also be present to multiplex the ADPCM-A and ADPCM-B data accesses to the V ROMs.

This is the main difference with MVS cartridges and is the reason MVS to AES convertors were made.

The cartridge connector has 2*2*50 (200) pins. See pinouts.

-*The PROG board which holds the [[P ROM|P]] (68k code) and [[V ROM|V]] (samples) ROMs.
-*The CHA board which holds the [[C ROM|C]] (sprite graphics), [[V ROM|V]] (z80 code) and [[S ROM|S]] (fix graphics) ROMs.
-A [[NEO-ZMC2]] chip is used to pre-decoded [[sprite graphics format|sprite graphics]] (and fix ?) to be output to the cartridge edge. It is also used to direct the [[YM2610|ADPCM-A and ADPCM-B]] data requests to one V ROM.
