I recall seeing some people trying to give it a shot but nothing's ever come out of those and the reproduction carts have been out of stock for a long time.

Looks like it's a hybrid between the NWC board but using an MMC3 instead.

In this picture: https://gamesniped.com/wp-content/uploa ... es-pcb.jpg

I see:
top left corner
74HC4040 DIPswitch
74HC4040 74HC30
74HC4040 74HC04
CIC
74HC11
QFP44(MMC3?)

top right corner
DIP4(optoisolator?) 74HC74 DIP16(PAL?)
DIP20(illegible) 74HC161

bottom
8KBRAM UVEPROM(DIP32) 8KBRAM UVEPROM(DIP32) 2KBRAM

parts in yellow are also present on NES-EVENT, and I'd assume work the same way.

Without better pictures of the board, or someone having taken the ROMs out the of sockets to read them, it'll be hard to figure out what's going on.

Reason: highlight similarities to NES-EVENT

It has been dumped already, has a mapper (#555) assigned for it, and is in the NES 2.0 XML Header Database. It will be the dumper's decision whether or when the dump will be released.

So since we have a md5sum and the sizes, you can start trying every possible byte combination until it matches :mrgreen:

If you're lucky, you get a working ROM immediately. Otherwise until the heat death.
