Hello all,

I am using scc-1’s MPU401 to talk to my MT32. Since I often run into Buffer overflow / Exc. checksum err situation I want to use softmpu purely as SysEx delayer.

When using softmpu /mpu:330 /delaysysex my mt32 correctly shows SoftMPU. But each sierra game will hang during start. The MT32 transmit light is working for some seconds and than rhythmically just blinks without the game starting.

Am I doing something wrong / do you know about any solutions for this behavior?

Thanks a lot

You're not doing anythng wrong. Which system are you using with the SCC-1?

On my Packard Bell Pack-Mate 28 Plus, I used SoftMPU for a bit before I wrote a program that turns off the cache for certain games (that are either speed sensitive for both the computer and Roland MT-32) and it'll turn on the cache once the game exits.

Here are the cache control programs that I use on my machine.

Cacheoff - turns off L1-L2 cache
Cacheon - turns on L1-L2 cache

I also wrote a lot of Batch files and I have the following entered when I want to load a game:

SIERRA.BAT (example)

I’m trying to use SoftMPU on my Windows 98 machine but I get an error telling me that the port trap failed. I am using QEMM 9.0. QEMM 7.5 caused SoftMPU to crash when launched, and EMM386 wasn’t detected by it. I am using port 330 for the MPU address, and my sound card is using IRQ 5 and Port 220.

My specs are as follows:
Pentium II 400Mhz
128MB RAM
Compaq 332857-001 Motherboard
Geforce 2 MX400 graphics card
Ensoniq ES1373 AudioPCI sound card

So is this usable with AWE64, as Aweutil doesn't emulate intelligent mode of MT-32 that some games require?

Can you "see" the MPU-401 MIDI port in DOS?
It's been a while but, I believe you require a DOS driver to enable the sound card under DOS.
And, as I recall, there might be compatibility issues between EMM386.EXE and PCI based sound cards in certain cases.

The purpose of SoftMPU is to emulate an intelligent mode MPU-401 MIDI interface using supported sound cards that has a UART mode MIDI interface.
So, by outputting the MIDI data via your MIDI/joystick port to an external device (like the MT-32) SoftMPU would then emulate the intelligent mode MPU-401 MIDI interface for you for those ganes that does require it.
Aweutil has a totally different function.
