No worries. Somebody on facebook helped me figure it out. I was neglecting to zero a counter during my font loading!!! On Vice I had it set to zero the whole memory on boot, which meant the variable was zero. On the real hardware (and other peoples Vice) it messed up as it wasn't zero. A waste of time over a total beginner mistake. I feel silly.
Anyway, fixed now. Well on the way to being a "game" I think.
Your "simple" VDC images are amazing... these remind me of my lamegame for the C128/VDC. In particular, the custom font of "text-mode"...
This is great stuff, so THANK YOU for sharing!
I hope that someday you, I, or another Commodore fanatic, will release a game showing the full potential of the VDC in a video game! In other words, lame text-processing doesn't count.. I (we) want to see full-screen scrolling graphics, with tight player controller... like the classic Spy Hunter.
I realize this is just a dream, but I hope we can all agree this a REALISTIC (achievable) dream!
Funny that Spy Hunter was mentioned. I actually made a bit of progress with that. I had a smooth scrolling multicolour bitmap road. I was working on making the "sprite" but as with all my VDC code, that is where I have paused
I might have another go at it so I can make a video for you showing the scrolling road and (stationary for now) cars.
I just recently got my "devel" PC up an running, so I haven't had time to test your software...
But I do want to say that I published a fast-running 3D-ish program that resembles the screen shots you posted. It is basically a time-limited, maze-running game called "moob". A playable D64 and full source code is available here... maybe some of that will inspire you?
Sorry that I am not a graphic artist, so I don't think I could really help in that department...
Anyway, best of luck with your project... I hope I can play it some time soon?
