Wa-Tor for the MEGA65

Hi all

here's my little MEGA65 implementation of the "Wa-Tor" population dynamics simulation

(see https://en.wikipedia.org/wiki/Wa-Tor)... start it from C65 mode and enjoy

Kind regards,

Stephan

P.S.: Source code is here: https://github.com/steph72/m65wator ...the whole thing is written in C, and compiled with cc65. Although it's quite fast and I did every optimization I could think of, the speed would of course be even better with a 45gs02 optimized compiler...

oops, I managed to sneak in a little bug (fish/sharks swapped in config menu...); here's a corrected version...

have fun

Do you use some special MEGA65 code? The program don't work at the C65 (xc65 emulator).

Yes, for the display updates I'm directly accessing the colour RAM at $ff80000 via the Mega65's enhanced DMA lists, as well as moving the text screen out of the way to $40000 ... all three things wouldn't work on a "normal" C65...

Great work! It looks very nice!

Thank you very much

After having received my JTAG programmer today, I was finally able to use m65 & m65connect to weed out the remaining bugs of my little population dynamics simulation for the MEGA65... and here it is I think it's a nice little demonstration of what the 45GS02 is capable of

what's new:

- re-written and recompiled with 45GS02 optimizing KickC compiler: roughly 4 times faster!

- less than half the size

- runs in C65 mode

- did I mention it is FAST?

a few technical points for those who are interested:

- uses extended DMA to quickly access the M65's colour RAM

- uses H640, & interlace mode to display wa-tor's ocean

A thousand thanks to JesperGravgaard for his awesome work with KickC!
