Tiny Yarou ( https://twitter.com/tiny_yarou / http://www.tiny-yarou.com/ ) made a Sega SG-1000 game loader for MSX1. It doesn't have sound, but otherwise works from what I have tried. :)
It's only 220 bytes! I haven't looked at the disasm. I suppose it does a brute search for I/O ports and changes them, if that is so, I'm surprised it works so well.

The sg-1000 has the same sound chip of colecovision
Maybe sound could be emulated resorting to hbarcellos work

No, there's no noise. (No fourth voice)

OK but, this is still a beta version:

It's based on the disassembled first version. I added a custom patch for each game to avoid bugs.

The sound is exactly as original games if you use the following cartridge otherwise there is no sound:

Now 46 titles work very well.

Yes but only games that use a VDP screen mode of SG-1000 / MSX. (Only a few Korean games)

Hi gdx!!

I tested Pitfall 2 and H.E.R.O from SG1000 and both works perfect!!! In TurboR ST and Philips 8245
I can play from my Megaflash SCC+ SD without problems.
It's a pity that the sound does not work.

Keep up the good work!!!
