PS1 DVD Logo Demo
By Alex FreePS1 DVD Logo Demo is a small demo for the PlayStation 1 console. It essentially demonstrates the following features/functionality:
- Bounces a large 128x74 DVD logo sprite around a screen (of 320x240p resolution) at 60 FPS.
- The DVD logo sprite can randomly change to 1 of 7 different colors each time the logo bounces off of the screen and changes direction.
- When an exact symmetrical corner hit occurs, an ‘exact corner hit counter’ will appear at the top of the screen after a very brief screen flash of white, as well as a message explaining the controls to dismiss said message. Press DPAD-UP on a controller to dismiss it until the next exact symmetrical corner hit occurs, or press DPAD-DOWN to dismiss it forever. The message explaining the controls will automatically disappear in about 30 seconds after first being displayed if you do nothing. If you do press up or down on your controller, the message explaining the controls will disappear along with the ‘exact corner hit counter’.
All Japanese and American PS1/PS2 consoles are supported as they have the NTSC video mode. Everything is currently hard-coded to NTSC 320x240 resolution, and the demo will currently not work on PAL consoles in PAL video mode. PAL consoles with an NTSC video mod would also work.
