Hi,
I want to start a public repository for dumps of all known MT-32/CM-32L ROM revisions.
Currently I host my limited collection via Google Docs, here: https://docs.google.com/open?id=0B5j-_ZMS8_Uo … DNmODY4ZjU5Y2Vi

A list of known ROM revisions can be found here:

I'd appreciate any help in obtaining more dumps.

Thanks!

ScummVM has added Munt into their project, but Munt is still an active stand alone project. Often, the Munt in ScummVM is outdated as Munt's development continues. The ROMs will do nothing for other synths, they are for Roland music only. If you want MT-32 music in DOSBox, you need a special build of DOSBox with Munt incorporated into it, the Munt QT app or, on Windows, the Munt driver. All of these solutions, including ScummVM, require the ROMs.

What about CM-32L music? There are a few old Lucasrts and Sierra Online games that use that one (since the SCI0 days, anyway)

It's been years, but if you're still looking for this stuff, someone is trying to assemble firmware dumps from all old synths, not just MT-32:

It has various versions of the MT-32 ROMs, but they're not compatible with Munt. They probably need to be converted to something Munt can load.

You need to join them together. One byte from ic27, then one byte from ic 26, then one byte from ic27, then... 😀

Yup. They need to be interleaved. I did that, and one of the control ROMs is weird. The 1.04, 1.05, 1.06, 1.07, and BlueRidge ROMs are already known to Munt. There's a new one (b__m-9.27c256.ic26.bin + a__m-9.27c256.ic27.bin) that is not. After interleaving it, it has these strings in it:

What the heck is that about 😕

Munt doesn't recognize it.

Update

The only things I was able to find out about "Real World Interfaces Australia" and "Robin Whittle" is something that seems to be a PCB design thingy for a memory board called "TX16W":

There's a scanned copy of the documentation for the RWI mod here; I think it's a firmware and hardware hack to fix the sound quality and add a pre-reverb output and battery backup. My MT-32 had this done sometime before I owned it (and this reminds me that I should check the battery...)
