>>> RottoprojoXL - Players and Missles <<<

I coded this one to prove that I'am absolute bad in many things... design, graphics, sound, cooking, ... but hell I do know size coding on Atari ;-)

Based on the awesome Rottoprojo64 Coder Pron coded by Skate / Plush. Man you rule! When I first saw Skate's prod I simply could not believe it. He did in 256 bytes what I had always planned for 512, one day, maybe. Later he posted the following and then I could not stop my synapses anymore.


I'll give you a nice example on how multiplatform 128b/256b or any similar size competition doesn't make sense at all.
Here is my recently release c64 256b (254 actually) cube rotation effect.
And here is the Atari 800 XL/XE port

Both machines are 6502 based and core code is exactly the same. But because of the c64 and atari sprite structure differences actually sprites are called players & missiles on Atari platform) Atari version is 384 bytes at the moment. It can be optimized but i don't think i will ever be able to reach 256 bytes. I'll try using graphic modes but i don't think it will help so much.

For three days I could not stop arranging the bytes in my head. Over and over again. Now I'm released from this pain. Phew. This version also has some "sound", "sync" and "colors" and I kept the original file size despite of my lovely 6 bytes Heather. With the optimizations contained here, the core of the computation is down to 170 bytes. So a C64 version would be much smaller but I'm preparing something that will beat it anyway ;-)

Until then you can enjoy this one on your Atari on on youtube.

The sad thing is that they didn't show the size in the compo, so nobody knew what you have really done!

Awesome! And I can't wait to see that your next trick shot!

Cool! That's the spirit

well, it's partially thumbing up my own code but you deserve it dude, i never thought it was possible on Atari 800 XL/XE platform, seriously. great optimizations on the core code and very nice missiles handling. :)

Yeah, that's a pitty but at least it has still beaten the BITS entry ;-)

I can't wait to see that your next trick shot!

No need to wait anymore: link me beautiful, ... which in turn was beaten by BITS - reality is so unfair. But, hey, we still have the internet :-)

'm not used to ATARI XL, but for 256byte, this seem a good technical prod !

I like minimalism!

Not bad for 256 bytes.
