sega has emulated the sega saturn but won't share
As for filtering, I hacked the gfx option from the 'popup' menu into the file menu and it works fine, You can change the fullscreen res on the fly and choose filtering. I couldn't get it to work from the .ini's though, same goes for 1/2 dozen other options.
Some random info:
Hitting F4 shows frame rate, res, priority and some other unknown crap.
Keys 1-0 disable different gfx features. Handy if priorities are a bit
wrong.
And according to a page on Saturn mods this is the complete list of
area codes.
1 Japan
2 Asia NTSC
4 North America
5 Mid + South America NTSC
6 Korea
10 Asia PAL
12 Europe Etc PAL/SECAM
13 Mid + South America PAL
