Re: New Dragon 32/64 Software
Don't give up! Today we have better understanding and tools that may help recover those tapes, and I would love to see your game! I also think that ROTABB was quite impressive. Good luck! And if you need some help, we are here for you ;) Just a quick update on the incomplete 'Black Planet' game: In...

MSDOS utilities
I've got a number of old PCs in the loft and have recently been trawling through them trying to find anything of use. In the process I found a couple of MS-DOS utilities that I wrote a long time ago. I've uploaded them just in case someone is able to make use of them. I haven't found the source code...

Re: New Dragon 32/64 Software
Many thanks for the kind words. I will give it a shot. I don't wish to hype it up too much though as it wasn't evolved enough to have any of the silly elements that I suspect gave ROTABB some appeal. I remember spending an afternoon with two mates just trying to think up the silliest level names we ...

Re: New Dragon 32/64 Software
I was working on another game for Kouga Software that never got completed... The initial concept was a vertical scrolling shooter heavily inspired by an Atari XL game called 'The Dreadnaught Factor'. This basically involved going up against giant spaceships, attempting to take out all their gun turr...

That's just pure genius. You only use your powers for good, right?

Re: Plasma Effect
Thanks tormod, I'm such a n00b. I've now updated the attachment to my earlier post. There is a new source and Dragon binary that updates at 50fps. The animation isn't as varied as the original but there might be a parameter tweak in there somewhere that gives a better effect. The screen drawing rout...

Re: Plasma Effect
I have some ideas that probably work better in my head than in reality :D I was thinking some data could be precalculated to allow one level of lookup to be removed, but I suspect the resulting animation won't be as complex. It might be useful for something though. I don't wish to abuse the board by...

Re: Plasma Effect
Nicely done sir! Self modding code on the pointers has really streamlined it.sixxie wrote:Something like this? http://www.6809.org.uk/tmp/plasma-new.s
Now all we need to do is pull another optimisation out the bag and double the speed again

Re: Plasma Effect
Yep, that kind of thing. As you point out, the same thing can be done with the y reg to get rid of the addb #2 which in turn means the t41 line can be moved out. Other observations: I redeclared the pos and neg halves of each table as macros just to make it easier to specify the doubled up tables, t...

Cheers!
