ZT link cable multiplayer support in D32XR

[viciious]

Unfortunately, it doesn't work. Connecting a 32X to MiSTer via SNAC doesn't result in a functional multiplayer, even though Zero Tolerance does work. D32XR uses the EXT INT function of TH, so that's something worth checking in the core.

May this possibly have something to do with the fact that the builtin MD core doesn't come with ENCC support enabled?

As per https://misterfpga.org/viewtopic.php?p=62388#p62388, "Zero Tolerance multiplayer works with the cable when run in the Genesis core, but does NOT work in the Super 32X core."

Genesis+32X and MISTer 32x core:

Zero Tolerance works

but D32XR doesn't

I can't help but wonder if this issue would be fixed if the 32X core were rebased on to the new Megadrive core.

Easier said than done, of course
