When I was referring to 'custom' commands in my earlier post, I was talking about the potential for a game and dedicated I/O to have custom commands within the JVS spec. Specifically I see 6F, 6D, 68, 6A, and 70 listed.Ĭlick to expand.With regards to the commands you'd want to send for profile switching, sure, anything outside of the standard JVS commands could potentially be used. I do see commands in in the range of 60-7F which would be unique to the game and I/O, but it looks like the code is generally getting way with replying with a standard OK ACK. A Sega Type 1 reports 13, so may fail due to that. Otherwise the standout difference between this reply an a Sega Type 1 is bits per player. Perhaps if there's a restriction it's in that a Sega I/O would have a few more features that it claims to have and maybe the game doesn't like that? Otherwise I'd suspect these are the minimum features required and maybe a standard Taito I/O doesn't meet these requirements? so the game doesn't care, right? It is a Taito game isn't it and would use a Taito I/O in the stock cabinet? Edit: I just noticed that it claims it's a NAMCO board.

Given that the ID contains the test 'no analog input' in spite of the analog being present makes me think the game doesn't care about the ID, or at least not the entire ID. I/O PCB-1000 ver1.0 for domestic only,no analog input' I notice compared to my standard features reply that this is not claiming any outputs.

Looking at the features reply, it look like it reports features as:
