I could probably squeeze in joystick control (I'm tight on memory though - more inlining of functions required)... the problem is that I need two "action" buttons, for jump and ???. Presumably up on the joystick doesn't work very well as a jump action.

I'm knee deep in finishing up my game, so I won't be able to get to it for a few days, but I can certainly add shifting/rolling, 8x8 mode, and some limited animation facilities. Maybe next weekend?

My randomly wandering creatures were behaving distinctly non-randomly, so it was easy to see :)

It doesn't look like he's updated his website in a couple of years, but I'll send him an email.

Since I didn't find anything on the internet, I just did an exhaustive search of the a and c parameters for a mod 256 Linear Congruential Generator, feeding the results into Monte Carlo Pi (PI) and Serial Correlation Coefficient (SCC) tests from "ent" (http://www.fourmilab.ch/random/). The...

The Fridge at Stephen L. Judd's ffd2.com site has some good stuff, like this random routine. I found a bug in the LCG in rand1.s (by comparing with the output from a C version): the carry bit should be cleared before adding $3611. So the code should be: GETRAND LDA RANDOM+1 STA TEMP1 LDA RANDOM ASL...

Unfortunately, though, i use Linux, not windows, and i can't get it to run in Wine. :( If you're using Ubuntu, you might want to try this, which would allow you to run the Character Editor in Linux: http://new.bigbluecup.com/yabb/index.php?topic=29886.0 It may not be worth the effort though :) On a...

Re: Multi-Color Character Editor

Welcome! Is this game still in development? Tell us more :) It sure is. I'm writing it with Acme and Vice for the unexpanded Vic. It's a platformer. I don't want to say too much beyond that... :shock: Awesome! I can't wait to try it. I would love to have DEC instead of HEX, but I may be the only on...

Multi-Color Character Editor

Hi, While developing my game I wrote a Windows-based editor to create multi-color mode graphics characters. http://www.kweepa.com/step/games/Vic20CharEd.png Clicking "Save" appends hex bytes to "chardef.txt." Download here (691k): http://www.kweepa.com/step/games/Vic20CharEd.zip
