Re: Update SC-55 ROM

Posted on 2018-04-04, 19:00

IIRC you need a 256kbytes rom so a 27C020 and variants will work fine edit: yep 27C020 is the correct part - I used in the past some 27SF020 eeproms look at the rom pic here: https://modelrail.otenko.com/retro/roland-sound-canvas-sc-55 So you can dump and burn eproms then? I've a request over in …

Re: Looking for DOS Menu Program

Not sure this is what you mean, but my actual retro gaming PC has an old menu system I use called: Fastmenu Gold Can't recall which version right off hand, and I do remember that it had nag screens so you would buy it and be able to customize it a bit more I believe? Still it was pretty easy to …

MT-32 Capacitor map and list of caps?

Posted on 2018-03-24, 03:12

I've downloaded 2 different service manuals for the MT-32, however, both of them only list like 4 or 5 actual electrolytic caps in the parts list? But all the photos of the mainboards I've seen for the Rev 0 and Rev. 1 boards have more like 20 or 21 electrolytic caps on boards. I know some of them …

Basically the more voltage you put into something, the more heat has to be given off to drop it down. So I began to notice this more with my old Sega Model 1 Genesis. Been fine for years, and then I got a Sega CD model 1 to add to it. I noticed one day when I left the sega CD bios screen just up and …

Should be fine, the amperage and polarity are whats most important along with the voltage. All unregulated PSUs without a load are going to read higher than they are rated at. The Idea is that they maintain that voltage when there is a load pulling on them. Heck I have several sega PSUs that are 9v …

Was going to add that if you don't have a power supply for these, that a Sega Genesis or in your case a model 1 megadrive power supply will work. Yes it has more amps, but that isn't a problem. I was using my MT-200 and MT-32 for about a week or so with a sega power supply until I got actual Roland …

Well I was using MUNT for the past couple of years, but decided to pick up an actual MT-32 about a month ago as I was able to snag one for about $70 shipped. Anyway, I can tell you that to my ears I can hear a definite difference between what I was listening to under MUNT and what it actually sound …

The SC-88 Pro has "MT-32 mode", don't have an original 88 though. The 88-Pro lists it as "C/M Mode" (Computer Music), and is meant to be compatible with CM-64. You might be surprised how often you can find this option. Even much later modules like the Yamaha MU128 have a C/M Mode. Sometimes they …

Re: Roland Sound Canvas Sc-55 and x68000 emulator

Posted on 2018-03-20, 13:38

I've gotten the x68k emulator itself running without issues through my MT-200. Not an actual SC-55 but as long as long as I make sure that my UM-ONE mk2 is the primary MIDI device in windows, the emu will see the MT-200 as a valid SC device (Because it is...) and use it just fine. I've not tested …

Re: Roland Sound Canvas Sc-50

Far as I know only the original SC-55 has an MT-32 mode and even still it doesn't have the ability to load up the custom patches and just relies on the default sound bank of the MT-32. That means, that while it might map to the MT-32 channels properly for the games that were MT-32 only, it still …
