BurgerTime Remake: The Road to DPC+



After recovering from the holidays, I finally got a chance to sit down and work some more on this.

What's new in this update:

  • The display kernel has been updated to take advantage of the DPC+ capabilities. Mainly this affects the burger pieces on the level which now actually look like the finished burgers... both in shape and color. This is done by utilizing DPC+'s fast fetch and the ability to write to Display Data to create a frame buffer for storing the burgers.
  • Also using Fast Fetch allows color and bitmap of both sprites to be updated every line... as opposed to the previous version which could only update one of the sprite fully.
  • Updates to the enemy AI now allow Mr. Hot Dog to chase the chef around. It still needs work though.
  • Still thinking about how to implement a round-the-corner algorithm for the joystick control to help ease the movement of the player thru the level.
  • I'm still planning to use the 20/30 Hz flicker routine (seen in the Pac-Man 4k remakes) to display upto 6 detailed sprites.

Lol, I see what you mean... and it was just my luck that when I took the screenshot, he was looking straight at me, making the accidental reference even more obvious. But he is a hot dog, so what do you expect? :)

I thought the hotdog already chased you around. IIRC, the others would take every ladder they came across until you finished all 5 boards. Then the breadstick would chase like the hotdog. Don't know who would do that next. It is really hard to finish 5 more with 2 enemies dogging you instead of just one.

Before, the hotdog only chased you around on the bottom platform. There was a flaw in the code that handled the vertical movement of the hot dog. He use to get stuck after moving up just a little bit. The fix for that came along with the fix needed to get the chef to actually obey the ladder locations. So now they truely obey the ladder locations. I still need to work on getting them both to obey the level platforms.
