I rolled up a quick-n-dirty simple retro birthday card for a friend. (No music.  Maybe for next year's card.)  (And, No, FillInTheBlank is not their actual name.   ;-)   )


Assembly code.  Redefined character sets do the animated flames.   Display kernel updating colors on every scan line.  lots of laziness in evidence.  Too lazy to actually do a VBI or DLI.




Assembly code is here if anyone is interested: https://github.com/k...ings/WIP-HBFITB
