New MSX to SMS Conversion Process

Recommended Posts

As many are aware, Sega Master System fans (centralized at SMS Power's forum) have long been converting Game Gear games to be compatible on the SMS using the Master Everdrive, for instance. Unrelated (you'd think), but during the 90's, Taiwanese and Korean publishers converted some MSX (originally SG-1000) games like Rally-X, Road Fighter, etc., to Master System. Why? Who knows! Well, someone discovered or obtained the software tools they used to do this. These tools have now been applied to additional MSX games with varying results. You'll have to follow the action at SMS-power, because this is all in its infancy at the moment, but cool nonetheless

Not exactly software tools.

These Korean/Taiwanese "conversions" has in the 0x000..0x3FFF area a kind of "msx1 bios", such routines (like i/o access) targeting sg1000/mastersystem hardware instead of msx1 - i/o ports are different, sn76489 sound chip needs to be treated as ay-3-8910, and ram memory arrangement is sometimes different as well.

What Korean/Taiwanese done there was concatenating this "bios" before the original msx1 games, and some of them work quite fine

Some of these are ColecoVision games, converted to MSX and then converted again to the Master System. Three degrees of separation!

And a couple games are official SG-1000 conversions to MSX converted back to SG-1000. Games already playable on JP SMS!
