In addition, I suggest using SDL which will work for windows. SDL is probably a much better approach than trying to directly access video RAM. And to makes things easier for you, once you learn to use SDL, you could write a wrapper module so you don't have to even rewrite your old programs :) cheers James > > ----- > L D Blake > > > _______________________________________________ > fpc-pascal maillist - [EMAIL PROTECTED] > http://lists.freepascal.org/mailman/listinfo/fpc-pascal -- - -Zero Defect Software Engineers Group - ZDSEG - -You need only two tools.
