Companions of Xanth MT-32 Problems

[ualaa1]

What happened?

Using the CD version. On the install screen when choosing MT-32 for music, it asks for the Mt-32 IRQ. The game recommends using IRQ 2. When using IRQ 2 and running the game afterwards, the game hangs on a black screen. Choosing any other IRQs will allow game to be played, but no music. 86-Box Sound settings:

Can you upload the VM please so I can attempt to reproduce this?

nvram too?

[TC1995]

also, your VHD seems corrupt.

[ualaa1]

Sorry for the late response, but here's the NV file. If the HD still seems corrupt please let me know. nvr - Copy.zip

MT-32 (in conjunction with SB) now plays the music when IRQ is set to, say, 5 or 7, however, when the MT-32 is set to IRQ 2 the game takes about 1:10 to load (shows a black screen during that time), and then although there's music, there's no speech from the SB.
