Hello all,

I installed Innocent Until Caught on my retro-PC and the game doesn't recognize the MPU-IPC card.
Error: "Unable to install sound driver"
Sound diver included in the game is "IUC_RLND.DRV"
The driver and the MPU-IPC are both hard coded to Port 330 and IRQ2, so they match.

This is the setup:
486 PC 66MHz
Sound Blaster Pro (Port 220, IRQ 5)
MPU-IPC card (Port 330, IRQ 2) This is the older version of the card, it has no jumpers
MPU-IPC connector box (connects to the MPU-IPC card)
MT-32 connected to the MPU-IPC box

Every game I've tried have had no issues with this setup, even when combining Sound Blaster Pro and MT-32.
The game works with SB Pro only.
Installed both versions of the game, floppy and CD-ROM, both have the same problem.
I have no clue what's wrong. I also tried the game "Guilty" (sequel of IUC) and it works just fine.

Any ideas?
Thanks and Merry Christmas!

Hello,
After a long time, I succeeded to make Innocent until caught using Roland MT-32 plugged on my AWE64PnP.
I did only with the help of this patched driver :

It seems that Roland driver for the game use only IRQ2 for the MIDI music.
So choose the driver patched with the right irq. For me, it's 5

First, delete the innocent.ini file and don't use SET_IUC.EXE

You'll have to make a batch file a correct parameters :

IUC.BAT

SETSOUND=.
SET BLASTER=A220 I5 D1 H5 P330 T6
LH SOFTMPU /SB:220 /IRQ:5 /MPU:330
innocent /r+ /b+ /m+ /x+
