Learning to program the V9990 VDP
Having a V9990 VDP attached on my CPC and always eager to learn about and program it. First steps are reproducing the "Robot" demo which were spread around the net to show little of the capabilities of the VDP V9990 from Yamaha.
Demo File: For executing extract files on a CPC floppy or upload it on the M4 board and change directory into the DSK container (|CD,"ROBOT.DSK"). Run file "ROBOT.BIN" and wait some time. At least a running robot through a forest will be shown.
You should be able to move (left, right, jump up) the robot via cursor keys and fire a bullet with space. https://www.cpcwiki.eu/index.php/File:Robot.dsk
