Guides or information on dumping MT-32 ROM?

[sofakng]

Are there any guides or information on dumping the MT-32 ROM from a real hardware unit?

I know there are illegal ways to obtain these ROMs but I have a real MT-32 that I'd like to desolder/dump the ROM myself if possible.

If you own the hardware it is absolutely legal just to go and download the appropriate firmware from anywhere on the web - just like with any other hardware you have (MB, Video Card, etc).

Thanks. I'd still be interested in the knowledge since I'm still curious.

Also, are there known-good MD5/SHA1 hashes for the ROMs?

AFAIK there are hashes in the munt code for various versions.
It would be interesting how dumping works for me, too. Though just theoretically, I don't think I'd want to really try it with my hardware.

The straightforward ROM dump may be obtained by using a special tool f.e. from XGecu (http://www.xgecu.com/en/) like TL866II or newer versions. You just insert the ROM IC with correct orientation, select the appropriate IC-type from the list in the bundled software and save the dump. The IC type will be different because of differences in "Old vs New style" MT-32s. The type and size of Program (Tone) and PCM (Wave) ROMs are also different. So select types accordingly. All details about IC types could be found in the Roland Service Notes.

Nice table of ROMs and their hashes could be found here: https://github.com/dwhinham/mt32-pi/wiki/MT-32-synthesis

Awesome -- thanks so much for the help!
