; 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 "!!!"
