SG-1000 to MSX Conversions By Me (Inspired By Hap)

I've decided to try something new. I've done 5 SG-1000 conversions for the MSX. I've followed it from the Bomb Jack SG2MSX patch. To be honest, they all work well, although there is some problems. As I followed, the SG-1000 uses BEh and BFh, while MSX is 98h and 99h. They're both Z80 processors and they're similar, but they don't use the same sound chip, because the MSX uses the AY-3-8910 and the SG-1000 uses the SN76489. They all don't have sound, but Nyan Cat already had no sound to it. Is there anything wrong I'm doing here?

I also did change the controller ports too.

But, the controls don't work.

I wanted to have a go today at these, but... without controls that will be quite hard

Yeah, I even try to follow how to use the controls and try to get the music codes converted too, but lucky for you, Nyan Cat works well without the controls and no sound because that's how it was.

I might even ask Hap if there's anything wrong or what I need to change in these files.

Nevermind, I am working hard on controls and I'm done with the SN76489.

Look into SG1000.COM source code, it's very easy for controls. You can see where and how it's patched for audio, controls, and VDP. All games work perfectly. I was not able to make to work one homebrew only.

SG-1000 games are much easier to convert than Coleco games.

I've done some SLotman related stuff too. Right now, this conversion of Choplifter is a WIP. Either the loader SLotman has worked on reads the controls or there are some redirects.
