I'm running into an issue and I'm not sure which part of my setup is the issue so I thought I would start here. I have a Mister FPGA setup using the Mini-ITX Ironclad Plus board from d3fmod. When I hook up an external mt32-pi to the user I/O port it works perfectly fine in the standard ao486 core. I tested it with King's Quest VI and everything works great. I also have the mt32-pi hat from d3fmod that lets you mount the mt32-pi inside your case using the second user I/O port. On d3fmod's site he states:
The mt32-pi internal hat uses the secondary user i/o port so, for now, it needs modified cores to work
And he points to two different places to get the cores depending on which page you are on:
https://github.com/MiSTer-Enhanced/Dist ... /_Computer
https://github.com/antoniovillena/2ndus ... r/releases
I have tried all four of the "plus" cores he linked to and none of them work. When launched, all video output from the Mister is disabled and I cannot bring up the on-screen menu. I can still SSH in, so it isn't locked up, it just isn't outputting video. Do any of you have experience with these "plus" cores? Is there a trick to getting them to work? Do they require a different BIOS? I also noticed that their file size is significantly smaller than the normal ao486 core, so maybe there is something wrong. I would appreciate any suggestions you all have. Thanks!
