Add TMS palette switch to Master System #107

Closed MinecraftMario27 closed 5 months ago

MinecraftMario27 commented 5 months ago

Can you please add SG-1000 II mode in Master System Type option. SG-1000 II allows 8KB RAM games for example: Taiwanese MSX Conversion on SG-1000 II, Korean MSX Ports on SMS https://www.smspower.org/forums/13579-Taiwan8KBRAMAdapterForPlayingMSXPortsOnSG1000II

It basically is emulating an SG-1000 II with 2KB of RAM, as I didn't know of any game running only on the original SG-1000. Is there any game requiring the original SG-1000 RAM setup? Is there a problem with some SG-1000 II game you noticed?

Correct me if I'm wrong, but aren't some of those SMS games? At least smspower.org doesn't have Super Boy games listed for SG. Could you please try running those games with the system set to Master System?

Those aren't SMS games. It actually uses TMS9918 mode. Super Boy I, Super Boy II, Super Boy 3 uses .sms file extension as Master System game but it's actually TMS9918 mode display. Master System / Mark III is backward compatibility with SG-1000 / TMS9918

When I set to Master System mode or Auto but it's dark colors but that is how they looks on real Master System / Mark III hardware.

TMS9918 mode can't be displayed on Game Gear and Genesis/Megadrive hardware and it displays black screen

So this is not about SG-1000 II but either:

Yes

I'll go with the palette selection as this is much easier to do ;-)
