We had one of these consoles when I was a kid - http://www.sc-3000.com/index.php/The-SEGA-SC-3000/SEGA-SC-3000-Technical-information.html
I read palette restrictions 16 colours with 16 shades of each.
Just wondering if anyone knows more detail about that palette?
I'd like to have some fun drawing something with that limitation :lol:

Found some info on the NTSC version, dunno if yours was PAL or NTSC (your profiles says Australia and I think you use a PAL variant for TV signal there...). Chipset to generate image data whould be similar or even the same, the difference restricted to the the TV signal generation. Video chipset seems to be generic TMS (MSX-I)

RGB specs for fixed palette modes for TMS (9929 is the one the console uses I think) chipset http://atariage.com/forums/topic/155790-tms-9918a9928a9929a-colors/
hope this helps

Thanks dude :y:
So maybe something like this is my restriction?

I don't want to be super-anal as long as it's fairly accurate just out of interest what can be done with that palette and res compared to the games then.
From initial description I read there were heaps more colours to work with but appears not to be the case.

As far I can tell yes... The chipset feautres (http://en.wikipedia.org/wiki/Texas_Instruments_TMS9918) implies it has only a 16 color fixed palette, 15+transparent in fact. Chipset TMS992X are PAL variants (50 Hz Y / R-Y / B-Y)
