I totally realize that lo-res / colour demos is 90% of the ST "business"
now. But actually if i cut "hires" from my question rest stays the same... You can draw with line-a, vdi some asm perhaps etc. in 320x200 as well.
Maybe what i am missing now is the "supervisor mode" :/ I dont know how it works and what it can provide. So if i turn this mode on will drawing routines be faster or what?
Anyway thanks DarkLord for these links!
