yeah, it seems to be "satellite-only" game, which uses not exactly same as usual comm.board, this game expecting it to be at 0x01A0xxxx, not usual 0x01A1xxxx, not sure if a mirror or a bit modified PCB.
"Slave" looks like client/player game unit,
"Relay" more like unit, which may show screen from one of player Slave units, "as is" or at different view angles (i.e. might be used to build multi-screen display), and also play music (Slave units plays only sfx, that's why Relay have 2x large sound ROMs).
I'm still not sure about Main/Master, it might be one more Model2 PCB, or some simpler relay device, some kind of network hub.
anyway, using a bit of debugger trickery I forced it to show something.
I've also hacked Slave ROM to think it is Master, added comm.board mirror, and it is happily passes initial networking check, but dies later.
because of different comm. shared RAM control locations (frame offset, size, etc), so current M2 comm HLE doesn't really work here.
perhaps we may ping Ariane Fugmann, who did good work on M1/M2 comm.BD HLE ?
I'd guess it will be easier task for person who familiar with this stuff.
