In short, they are output ports. Used by the FCT1B board to multiplex controllers or by the Mahjong controller to multiplex buttons. On MVS MV1B and MV1C they are on a separate connector, which is not available on other boards. It would be useful to know if the joypad ports can be used instead.

I should've checked the Schematics, MV1F and AES as well: https://wiki.neogeodev.org/index.php?title=File:Mv1fs-page1.jpg https://wiki.neogeodev.org/index.php?title=File:Neogeo_aes_schematics_pal_2-page-003.jpg

Can someone with experience with/access to multiple board types confirm if the boards that have joypad ports: https://wiki.neogeodev.org/index.php?title=MVS_board_types Have OUT1-OUT3 wired to the joypad ports: https://wiki.neogeodev.org/index.php?title=Pinouts#Joypad_ports ?

You know you can just buy a larger shelf? ;)

The largest easily available 5V flash part that can be hand soldered I found is 39sf040, which is 512kB * 8bit. Larger chips are only available in 3.3V. The PGM operates at 5V. Going from a 3.3V output to a 5V input is not a problem, as that is still over the threshold that reads as 1 on the 5V...

Odd. :) I noticed he listed "Fluffy" carts, but just assumed since I released the Gerbers that he gives people a choice between lydz and my boards. lydz boards are easier to "mass"-produce, or maybe they've got lots of stock?

From what I understand the ngdev cartridges have an extra cpu on the program board, similar to PGM. In the end it is their decision, looking how quickly bootlegs appear on aliexpress it is understandable.

Ordered mine. Looking forward to it!

I'll have a look if I can automate the whole thing once I've got my own multi...

If you go into this with the right mindset, that you're buying a (probably good) repro, then there is nothing wrong with this. Maybe the price goes down a bit once all the rich collectors have one, then again, they may run out of components.

My NBM arrived, and I was able to test this with the UniBIOS, and the game reports itself as 4 player version: So far I've been unable to test an actual 4 player game, though... The best I get is 2 players against 2 AI, with one player playing the main char and the other the tag buddy on the...

Though there was a time when custom PCBs were unaffordable without a significant investment, or making very small numbers etching them yourself. There are now things like https://tinytapeout.com/ , and there are companies that can turn your working FPGA design into an ASIC for something like...

1 please!

I'm getting 403 forbidden for the image.
