Your framerate should drop only to about 15, as the memoryneeds are bigger. When I used banked modes I used a doublebuffer to write to(fast, no slow videomemory), and then , after all drawing, I just flushed it onto screen, top down. This needs just a couple bankswitches, and is OK fast. Ludvig Larsson. ps. I use memcopy instead of dosmemput, no idea of importance. pps. Some gr-code is avaliable at my homepage: http://www.geocities.com/TimesSquare/Arena/1645/index.html
