Since I upgraded my MU2000 to the EX firmware, I lost the TG-300 mode. This was a few years ago, but I remember it sounded different to my actual TG-300. However it may very well be that the MU2000's audio out via TOSLink was so clean, it made it sound different. I've often wished that I had spent a few months comparing the two.

I can say that the TG-100 and 300 are great little midi boxes, and I haven't heard any game sound bad with them. However, I find X68000 games that have a GM option (instead of Roland SC-55), to sound the best with either module. I can only guess that on an original MU2000 via TOSLink they would truly shine.

That's good to hear! I'll add the TG-300 to my list of modules to find.

The 100 will have the same sounds as the 300 as far as default GM is concerned. The 300 has extra stuff for making music. If you're only concerned with games, consider the 100 as an option since its often cheaper and easier to find. It's also very small and cute.
