I don't really have answers to these questions at this point. I do know that I intend to take shortcuts for the sake of efficiency when needed, which may impact game features. I also know that the "feature set" will be limited because my attention span is limited and my ambition is only to...

Yeah, that might work, thanks! The problem is that the marbles roll at arbitrary orientations and in arbitrary directions so the blurring should be different, but it might be helpful to just blur the texture in a general way. I'll give it a try sometime in the future unless a better idea...

Heh, everybody who pre-orders gets their avatar on their own custom marble! Edited to add: just a joke, this is not a commercial game

Oh, actually, all I really want to do is identify whether a unit is a Mk1, so that I can adjust colors in my game to compensate for the differences in the LCDs. I did try putting identical firmware versions on a Mk1 and a Mk2 and reading all the mmsp2 registers that might relate to the LCD in...

As I had envisioned the game prior to starting (such visions never survive intact, but still), there would be sections of a track where (because of obstacles, tight turns or other reasons) the marbles would have to roll slowly -- to give a contrast between slow movement and giddy...

Probably "the textures" is the answer, although the actual method is more like simplified ray tracing. For each point, calculate the intersection with a sphere, then apply the rotation matrix to the result to either give the basis for a procedural texture (like the middle marble) or the means...

I'm starting to get the marbles sorted out, though I don't quite have mastery yet of the rotation/quaternion stuff. I'm mostly pleased with the drawing, which is a tradeoff between quality and performance, like everything else. I still might have to squeeze some more speed out of it, but it...

Heh. I would never compete with you Squidge, it would be hopeless! I got the Valavan Manohararajah source code that most people seem to use; it's too slow, so I'll need to optimize it some, which will be an interesting experience.

Well, I tried all id and address combinations; it seems the only id that works is 0x8A, and all addresses for that id return 0xC3, which is apparently a device id of some kind. Oh well. Maybe I can try hacking into gp2xmenu to see how it gets the data. That will be pretty hideous. Sorry to...

Thanks rlyeh, i did try that (having found your code via google), but couldn't get it to work (all addreses returned the same value). I'll give it another shot though, maybe I did something wrong.

Speaking of the hardware, does anybody know how to get at the i2c memory in the newer firmwared? /dev/i2c-0 doesn't exist any more. More specifically I'm trying to get the serial number.

Thanks, I'll get to work on it right away.

Normally I am not interested in emulators because of the "using people's code against their will" aspect that is usually involved in getting ROMS and pretty much always involved in the device's operating system. Reading this thread has gotten me interested though, as it appears that producing a...

The Balrog of Burnout dragged me into the depths of the Khazad-Dum of Mundane Life, but I have emerged as Dzz The White! Hmm, a Potter analogy would be more topical, but I never did read those books. Anyway, I'm working on drawing spheres, which sounds easy but it's challenging to get it the...

Ask them what a PSP is, and whatever they say, say "yeah, like that." This will confuse them enough to leave you alone. Or, tell them it's an iPhone.

When they say "use descriptive variable names" I interpret that to mean entire sentences with lots of adjectives.

I bought it because it is a handheld that encourages independent development and because of its active community (which taken together guarantee a stream of stuff to play with and an audience for new stuff).

This is all still basically proof-of-concept phase, but you can get a better feel for the background idea by downloading http://www.dzzgames.com/nr2.gpe Controls are the same as before: L/R, A/B, X/Y You can see the distortion at the poles in the texture map I'm using here: It will serve...
