Hello, i have converted the 3D Stars routine from the fridge http://www.ffd2.com/fridge/chacking/c=hacking16.txt to VIC BASIC with the MG expansion from Mike. It is so slow. :shock: Does anyone have an idea how to speed this up in BASIC? This is the original code. 10 rem starfield 15 mode16:gron16 2...

Hi, i think the Commodore VIC20: Software Sprite Stack library is the best address for this. We have no in game scrolling, except when the level changes and I can do that in Assembler. ;-) Or see the book "Programing the VIC" from Compute! on page 390 and 400. I found a comparison video fr...

Hi @ all,

I am very interested in implementing Bubble Bobble on the VIC. How can I support?

I have an TI-84 Plus here on my desk.

https://en.wikipedia.org/wiki/TI-84_Plus_series

The Z80 is alive!

My Assembler load the program with Load"Demo",8 ant not with ,8,1.
Could that be the error?
And how do I change my basic stub to load the program with .8.1?

Good morning, thanks a lot for your help. Bur, it wont run. If i run the program from my assembler compiler the same failure occurs. The data of the sprite is not correct. If i change the register $9005 from $F0 (240) to $FE (254) the start text cannot be seen. And vice versa I see the text but the ...

Hello,

Is there anyone out there who can help me with my question? I can't find the error in the program or in my thought process.

Thank you

Who decides what legitimate applications are?

I use the line routine from Bitbreaker from codebase64. https://codebase64.org/doku.php?id=base:bresenham_s_line_algorithm_2 The results are very good. Line x0,y0 to x1,y1 Cycles in total xxxx per pixel yy 00,00 to 99,00 5219 per pixel 52 00,00 to 00,99 5219 per pixel 52 00,00 to 99,99 5516 per pix...

… but the Demo is very impressive.

Hi,

during my search of the best line algorithm i found this website.

Hi Mike,

of course, you are right. Thanks for the tip.

Dear all, Do any of you have a very quick line drawing algorithm that you can share here? The one I'm currently using is from the site https://retro64.altervista.org/blog/category/programming/ and probably not the fastest. I would be very grateful for suggestions, tips and of course complete code. W...

Yes, I mean some screensavers can be implemented with the F2 key. But this is only a gimmick.
The IRQ clock, i mean could be placed under the normal screen. And of course with an alarm set and alarm tone.
Even just a wish. But then the FE3 would be perfect.
Or what is the RTC for?
