Gp2x Demo Competition: 750$ prize money

[Dzz]

I just started devving this week. Finally got a BoB to unbrick my 2x thats been sitting idle while I sit bored. I plan to have an entry, but its going to be nothing spectacular. So far it's just a bunch of balls bouncing around the screen with crap textures. Work in progress:

(note: the binary is under 10k if i get rid of the text on the screen)

The header overhead is not a huge consideration for anybody who isn't trying a 4k demo. It's a couple hundred

Is there a 4k category that I did not notice?

There is no 4k category.

Thats cool, my demo has been in dev only 2 weeks. All i have is a rotating cube, i just tried
to pile on the special effects.

EDIT: I tried your little demo, thats awesome, i didn't realize you had some physics/collision stuff
in it.

There is no 4k category, but there is a 64k category so you have a bit more leeway with the size.
But read the actual description, as there is some extra stuff you have to do when handing it in.

I plan to send mine to Dzz tonight, im not going to get much more done. Id rather start working
on my gp2x game!

Well, since there isn't a 4k category I guess I will stop squeezing my binary. It's just under 10k. I could make 8k for sure, 4k if I killed some of the functionality (namely rotation. could drop 3k in a heartbeat if i didnt have trig lookup tables). But there's no time I am also submitting tonight, but only because I know I wont have time to work on it tomorrow. I actually plan to develop mine into some sort of game, possibly pool or pinball. Heading in that direction gives me an excuse to continue improving my fixed point library.

Ok, after reading this entire thread (as well as gp2xdemo.com), i think i need some clarification:

My demo gpe is below 64k. And it runs on a stock GP2X with firmware 2.0.0 , bought
online about 2 weeks ago without any added files. ie, I haven't touched the NAND and the
demo can run if it is alone (no other files at all) on the SD card.

BUT, my demo uses non-static SDL. Does this disqualify me from the 64k category? As it requires
an external shared lib?

-Twixn-

EDIT: Nevermind, i managed to rid my code of all traces of SDL and do the lower level stuff myself.
WOW, i can't believe how much faster it is because of it! Much easier than i thought too.

 

[ragnor]

I wish i could have time to do that, damn SDL is too slow for this . Anyway, mine is some oldskool crap (again ) and will be post to Dzz today. (Yes, its ready)

 

[twixn]

I think i was lucky, i didn't use much SDL so it was easy to replace (took me about
10 minutes).

But anyway, Good luck to everyone who entered!

Now...time to start working on my game

Nice one, guys. Great to see the entries coming in. For a while I was a bit worried only Rixed would be entering.

Just for completeness, I'll answer your question: It would have been fine before.

Hmm, well its still good i got rid of it. SDL is great but i needed the speed of doing it myself.

Did you get my entry? I sent it yesterday (well, about 10-11 hours ago).

I may not have all the mail where I am right now, but I do not seem to have it in my inbox. Could you please resend it to dzz@gp2xgamer.com? I may actually have it but cannot get at it this minute, but just resend it anyway if you don't mind, just to be safe. Thanks!

Ok done, if you dont get it i'll put it onto my webspace and give you the URL.

Thanks for the quick reply btw, i was unsure if you got it.

Our (me and my friends) work is done finally. And our entry sent to you Dzz.

I wonder how many differences of color-cycled plasma we are going to see (and on the same subject, infinite bobs)

You cynic!

Web site updated. 24 hours to go!

A few last minute questions...

The rules specify 5 minutes maximum. Does that mean the demo has to terminate itself or just that you won't watch it any longer than that?

Have you recieved my entry from sparr0@gmail.com?

Will your GP2X be overclocked?

Will our demo be launched from the GP2X game browser?

If your demo runs longer than 5 minutes that's fine if I can exit it.

The gp2x will not be overclocked. I suppose you could overclock it yourself in the software, but if you push it past a bare minimum level there's a chance that a judge's gp2x can't handle it (not to mention your other future audience)

Yes, the demo will be launched from the game browser.

You may want to pop a link to the demo site on your normal site, took me a while to find the link in this thread.

P.s. Who's done a demo? I've sent mine in, don't expect amazing things from it, only started it last week then got board. Its got a voxel terrain so thought I would sent it in anyway.

Voxel landscape? COol! I'd like to see voxels in GP2X, tried twice in the past to code mine but never succeeded to make it work or look good

I've finished with my demo too. It's a very hurried work, two days before the deadline, though it has some nice 3d code. I was about to not contribute anything because I was too unmotivated and time was short, but before yesterday I decided to connect some parts and do something just for the contribution. Lol! I am sattisfied for two days of work. Nice to see there are also 5 other entries there.

 

[DaveN]

I think there'll be around 10 in the end, the one's on the page, the other one's mentioned here in the thread but not on the page until now and finally the one's who haven't submitted yet. I'm really looking forward to seeing these things, I'm into most demos.

So good luck to everyone!

 

[twixn]

Heh, so am i. I'd like to see what people come up with, it looks like most of the demos are
last-minute.

Mine is small, its mostly just the 3d renderer im developing with some added effects
(some good, some useless, but all pretty ). Hopefully it wins a prize, but im happy
to have participated anyway.
