    The Wiz Gets Proper Buttons And A 3.5mm Headphone Jack

    fantastic! i'm excited now. ideal for oldschool gaming, extremely portable, even some 3D capabilities, and relatively cheap. this thing will *rock*! the EXT port still has me puzzled. it's great that it's a samsung external port, but.. what can it do except for USB? will TV/VGA-out still be an...

    Congrats Hedelmae

    Finally saw it! One of the top-three GP2X demos!! Congrats! :) http://www.pouet.net/prod.php?which=51131

    How's Picodrive Looking

    Those videos are pretty hot. And that's at a 'mere' 500 MHz. Wow!

    Voxel Demo

    did the same on atari falcon 10 years ago now (time flies..). the PC source (or at least half of it) + commanche map was available on the net. congrats on the nice port.

    Memory Card For F200 Model

    this is good news :) btw, is it the new firmware that gives the SDHC support? Or is it the new hardware in the F200 (.. since i also have two F100's.. )?

    I Just Got My Gp2x!!!

    got mine yesterday. the white is pretty girlish. other than that it's a nice piece of kit. the controls (d pad) seem ok. the stylus works but i haven't tried Atari ST emulation (yet). i look forward to messing around some more with it. :) the 4GB SD card sounds like good news to me btw!

    Anyone Know Where To Find Surplus Gp2x F100 ?

    wtf, that panda gp2x container is nice! i guess they must have incorporated 3.3V power for it as well. and the networking sounds sweet :) (prolly damn expensive, tho ;))

    GP2X Gp2x Dev Station

    thanks for the replies all. yea, it's a slightly mad concept. and the RAM argument is a strong one. using TV out is pretty ok imho. tiny C + ramdisk is probably is the way to go.. if i still want to proceed with this =)

    Our New Machine, Pandora

    psp will certainly not be a target for emulation (see also the bluwiki page). i think the omap3430 will be better than psp, actually (but not by a factor 10, which is required for emulation). offtopic: even though psp has quite advanced stuff like hardware acceleration for skeletons and such...

    GP2X Gp2x Dev Station

    you maybe have a point there. is gcc really this slow? i think it still comfy on a 500 MHz Celeron (okay, this is at least 3 times as fast as a gp2x). guess i could try to compile gcc for it.. but maybe this whole thing is a project in itself.

    GP2X Software S-buffering

    QUOTE This may be a rather stupid question.... but how can you sort from front to back when each span has an end and start z position? Or do you split intersecting spans.... you actually have to sort the polys, not the spans. so, just like with painters, but front->back instead of...

    GP2X Gp2x Dev Station

    since i got a cradle with my GP2X i hooked it up to a keyboard and used Sterm a little. i noticed it worked quite okay. i did the other usual stuff like reading some PDF's and trying some other programs with mouse and keyboard support. i almost got the good old home computer vibe back...

    GP2X Software S-buffering

    -- a typical span buffer rasteriser would work in two stages: ( 0) reset span buffer) 1) span conversion: this writes spans with interpolated X,U,V,.. coordinates to the span buffer. the span buffer is a data structure of linked lists for every scan line. nodes can be inserted, deleted (when...

    GP2X Software S-buffering

    i implemented coverage buffering (c buffer) which -should- actually be a faster algorithm than s buffer. in s buffer you store all the U,V,W coords for every span. in c buffering you don't but it requires an additional front->back sorting stage. i benchmarked it and it seemed that only with a...

    GP2X Little Help Porting Sdl App

    just out of curiosity, is it a real voxel engine (using raycasting) or using zbuffer/painter's algorithm polygons? about speed: gp2x suffers from low memory bandwidth to the SDRAM. but when stuff is in cache it's quite ok. also note that the ARM9 is not a superscalar cpu like the pentium, nor...
