Interesting, I didn't know I can daisy chain sega jvs io together. How does one JVS IO daisy chain to the other? Is it from CN4 of a JVS IO to CN5 of another JVS IO?
I'm trying to use the Multi JVS with a Maximum Tune 3 driving Japanese cab to connect to Naomi motherboard but the cab is using FCA IO pcb instead of Sega IO pcb so I can't connect the cab directly to the Multi JVS. Is the only way to connect the cab with the Multi JVS is to adapt the FCA IO pcb...
I'm able to swap profile now. Previously I copied "sd card contents" folder instead of just the files to the root folder of sd card.
I tested the Multi JVS with a Naomi2 motherboard and working good. I tested with a beat 'em up game with a neogeo controller and a driving game (I connected the...
To test the pcb, I would make sure I connect the pcb with an arcade machine with a Jamma harness and check with a multimeter all voltages coming out from the harness are 5v, -5v and 12v. 12v can be less than 12v I think. Then check again the voltage once connected the pcb and adjust them to 5v...
Blast city power supply doesn't produce -5V and Killer Instinct pcb needs it based on the user manual. You can check if your Blast City Jamma harness returns -5V.
I powered the board via micro usb when I tested the menu button. I didn't connect to any game motherboard yet. I copied "sd card contents" folder from the extracted github zip file to the root of sd card.
How did you test the board? Did you connect to a JVS motherboard like Naomi?
Maybe these manuals can help.

Oh ok. HAS video output goes to Analog RGB port. X68k computer video goes to the same port. I remembered I had to toggle between digital and analog between computer (digital) and game console (analog). But game console I connected to composite video audio inputs on the monitor.
