    GP32 Map File Storage

    I would suggest a chat struct, offers 256 different tiles. If you plan a user level editor, use text files. Like: wweeqewqerwqrertztt qwrtewreerwerwerezt weqere"§$§%§"2eww .... every char represent one tile. Remeber a 600x600 tiled screen (no matter how big a tile is), only use 600*600=360.000...

    Gp2x Mencoder Bash Script

    The -ffourcc DIVX codec is so old, and produces very bad encodings. If you want better quallity videos, you can use the divx4 codec from the ffmpeg pack, or the (prefered) xvid codec. Using ffmepg divx4 codec: mencoder -o movie.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=200:vhq -oac...

    GP32 Basic Sound Questions (using Mr.mirko)

    if the sound crackles, check your drawing to the screen, if your only drawing to the framebuffer, and not to some "nearby" memory. Are you using FRAMEBUFFER1/2 memory ? DO not use some malloc memory for framebuffer. Also do not use empty loops, like while (1) wait_for_keypress; Do remove all...

    Jtag? External Port?

    fpga chips are only for designing new chips, later then all is working, and the design is good, an fpga is no longer used. The chip hardware is build static. An fpga chip is to expensive for mass use. Also fpga chips are slow. ( e.g. you cant emulate an 2Ghz Athlon64, on an fpga chip ) cu...

    GP32 Devkitpro Error With Including Stdio.h

    Dont include <stdio.h> !!!!! They will conflict with the types in fileio.h implicit warnings are not "so" bad... They only mean, that there is no prototype found, for your calling function, but it is working 100%. If you want to remove the implicite warnings, add the prototype of the function...

    Any Update On 2nd Cpu?

    Okay, i checked the def of the word "useless", and it is used for things, who are broken, or can not get to work. I think i used the wrong word. Couse we all know, that the second core, is working.

    Any Update On 2nd Cpu?

    Okay, i think i should answer to this. to 1. I never said something against this... 2. The same thing, i posted here, no MMU, and the PU is useless, couse Linux can not use it. 3. I posted above, that you can run any code on it, and GPH is using it as an divx decoder. 4. same as 3. 5. I was...

    The Ninja

    It was not possible for me, getting any contact to Samsung. They (as company) will not cooperate with individuals. Solution: Build up a company ( like GPH, a 3 person one ) Try to get money, to build a prototype Find a company who can assemble the parts. This is a FUll time job... Its really...

    Any Update On 2nd Cpu?

    Yes squidge, a simple example, on how you use the second core under Linux, would be great, and how you access global data. You said its easy, your chance now... Please fill out this : char globaldata[8192]; int use_core2() { // fill globaldata with 0xff return; } int main() { use_core2()...

    Any Update On 2nd Cpu?

    This is not possible, and will never happen, couse Linux can not support SMP the way, the two cores are inside the CPU. The BIG Problem is, that there is no MMU ( Memory manegment Unit) in the second core. And Linux needs it. Without a SMP system can not work.

    Any Update On 2nd Cpu?

    The second core is only used for DIVX decoding ! Not for displaying the Video to the Screen . The 2D display unit, is a seperate unit from the two cores.
