I don't recall that the C64 had particularly complicated screen modes (were there more than two?), but it had a funny way of handeling it which made it virtually impossible to draw bitmaps with the 1MHz processor. In stead it heavily relied on sprites, which we all know is not very tricky. The thing about the SAM that makes it so darn difficult, is that you can actually DO things at the end of each scan-line, like changing screen-modes, select another screen to be displayed, change palette, etc. The mere task of keeping the timing of each line-interrupt will take a LOT of time, not to speak about how to actually switch screen, modes etc. on the fly. This is all in the SAMs hardware. Not even Z80 manages to emulate the (ab)use of the second screen on 128K 100%. > > -Andrew Gale > [happy Mr Burtenshaw?] > > > -- ^ One To-day is Worth Two To-morrows (Ben Franklin) ^ | ....or: One To-morrow is Worth a Quarter of One Yester-day... | | Frode Tennebo | email: [EMAIL PROTECTED] | | ECP/PT, CERN, Switzerland | http://www.hiMolde.no/~frodet | | Phone: +33 50 28 26 17 | [EMAIL PROTECTED] |
