Morning all,
Do any of you have the HSG (hi res graphics board) for the PET running at 512x512 ?
If so have a go at this asteroids port I managed to get to work with the board. I found a disassembly of the arcade version rev 4 and once figured out how the vector graphics worked and memory usage ported a version across.
Not perfect but very playable - I hope you don't have too much screen flicker - mine setup is OK
Keys (business keyboard)
Rotation : 4 - anticlockwise or 6 - Clockwise
Fire : a
Thrust. : s
Hyperspace : Tab
Rotation angle of the ship is in steps for faster rotation - finer movement is possible if you hold the shift key down when rotating the ship but the speed of rotation is slower.
One asteroid you need to hit dead centre for some reason, the others are easier to hit.
Thrust is relatively slow to start right now and could be sped up if needed.
I didn't port across high scores as not an arcade machine and the person playing knows.... haven't played it past 7000 points as doing testing more than game play.
