NEO TEAM Super MVS Converter II PLUS V7

Yuck !

Uses an Actel ProASIC V3 FPGA on each board. They're AES-decryption capable for SPI flash and fusemap update, and generally highly temper-proof.

Has two SPI ports for FPGA updates and one unrouted mini-USB port labelled "BIOS".

Boards dated May 2011. Seems to suffer of very bad soldering job on connectors.






NEO TEAM Super MVS Convertor II V5B

Uses a PAL18CV8 and two LS245 transceivers for the prog board. Two corresponding footprints for SIL pull-up resistors on the MVS side are left unpopulated.

Uses a custom chip "NEO CELL KS300 8436020333002 06-03" to simulate NEO-ZMC2. An RC circuit (potentiometer) is used for EVEN delay to make CMC games work correctly.

According to [these pictures], the chip would be a custom branded Altera MAX PLD. It's in fact en EPM240D (Boundary scan device ID reply with bus pirate: BB085040, reversed !) and the header on the back is for JTAG:
