forget "Mode 7" that was Nintendo's cheap, crappy implementation
of arcade-quality effects like scaling & rotation for the Super Famicom.
Sega's "Super-Scaler" technology for arcades in the 1980s, used in
Space Harrier, OutRun, AfterBurner II, ThunderBlade, Super Monaco GP,
Galaxy Force II and many others - was 'the real deal'
The SuperGrafx should've had something close to this that, even if not
quite as powerful as Super-Scaler, but better than Nintendo's lame
'Mode 7' -- sadly, the SuperGrafx did not even have effects on par
with Nintendo's crappy 'Mode 7'.
