- ; VideoTracker AGA developer source 25-12-93
- ; 24-bits colors, Super-HiRes, HAM8, maximum burstmode (64 pixels aligned)
- ; wich makes low-resolution overscan a bit ugly.
- ; no "interactive" support anymore, it's only used by Kick 1.3 users.
-
- ; the first part of the source handles the things that are necessary to
- ; show the picture/copper and playing of the routine.
- ; the part between the "***" lines is the routine-source.
- ; at the bottom of the file, there are the necessary incbin-files who
- ; are needed to test the routine.
- ; these are saved with "save effect" in videotracker. they are raw
- ; data files which can be fonts,pictures,landscapes,vectorobjects
- ; etcetra.
- ; the incbin-files are put in the "variables" table, in the routine
- ; player-handler
- ; the place where it's done can be found by searching for "!!!"
