Amiga Boing demo for Master System
Post Posted: Mon Sep 30, 2024 3:27 pm
Some time ago i made this demo in devkitsms which I already shared it on the Discord channel.

This is the first thing i made with devkitsms so bear with me :).
I borrowed a lot of code from the devkitsms pong tutorial. I must say the tutorial is really awesome and very rewarding. You can make something cool very quickly.
See https://www.smspower.org/forums/15888-DevkitSMSTutorial

Instead of the moving a sprite like in the tutorial, i am moving the background with the ball image on a black background.
The animation is all done with palette cycling, which changes direction when the ball hits left or right side. You can also control the palette cycling with left and right using the joypad.
Finally i had to hide/remove the grey shadow tiles as they would wrap around the screen when the ball is at the far right.
To restore the tiles i manually picked them (instead of loading a part of the tilemap).

Hope you enjoy!

A while ago i worked on this demo and added the background grid.

I wanted to add speed control, but got sidetracked. Maybe i'll add it in the next version.

I want to thank Sverx, Maxim, Joe and everybody else who helped me out with the code, optimizations and brilliant ideas!

Download rom version 1.01 here

This version fixes the small glitches which occasionally appeared at the top of the screen.
Had to do SMS_loadTileMapColumn later. Thanks again, Sverx!
