Yes, I can ping and telnet the gp2x but shares seem not to work. I now tried with Linux but there I also don't know how to get samba shares to work with gp2x.

The default values specified in the comments in the above source code were taken from the MMSP2 Documentation and as we all know may not necessarily be correct. You can use the cpu-lcd-ram whatever tweak tool to inspect the actual values in the registers after boot (note, you will have to...

Hi guys! I have to work with my laptop for a while now which has Vista Home Premium installed on it. I already can't use the devkitGP2X which I was using with XP since it is broken on Vista. I tried to get USB networking with the GP2X running and that worked without problems. I am having...

If you compile without optimization GCC will produce the worst code. I compile with -O3 -fomit-frame-pointer -funroll-loops (using GCC 4.2.1 on Windows 32bit) and I get 245-265fps on my 2.2GHz AMD Turion 64 X2 (only using one core). Strange enough a Release build with Visual Studio 2008 gives...

I never tested gpu940, so I really can't compare my renderer to that very much, but I am working on it for 9 months now and I believe it is very near optimal (asm could improve things, but I want to stay with pure C++ for now). But I can say that my renderer is way faster than Vincent...

Can this be true? Is there realy only so little interest in a 3d demo/game contest?

Hi! I did a demo for GBAX 2007 using my software renderer (search for F341 on pouet.net) and since then I heavily improved the renderer (The demo now runs 1.5-2.5 times faster). I believe it now is a very mature renderer with great performance (definitly faster than Vincent and reportedly 10x...

Hi! I updated the software rasterizer in the last few days, so you might wan't to check out the newest version. There is now also a second example displaying a 5000 triangle model of a cow with custom per vertex lighting. It uses my vector_math library together wich my fixed point library. They...

You may also want to look at my software rasterizer (look at my signature). It seems to be a lot faster than Vincent and is more low level and flexible (It would be possible to create an OpenGL layer on top of it). It is quite modular and only uses fixed point math for performance reasons. It...

Good to hear that :) You might also want to know that my fixed point library and vector_math library work very well together. When you use vectors or matrices of fixed point numbers the multiply accumulate operations (used in dot products, matrix multiplication etc.) will be optimized...

S-Buffer, C-Buffer. I think we are talking about the same thing here, don't we? From a fast google search I could find out that in the C-Buffer spans on the same scanline can be merged. But how should this be done? I mean one has to store the start and end U,V and other parameters for...

No, you would not have to modify anything in the current engine but only add new code. You can already input a bunch of triangles at once. Shared vertices are only transformed once as there is a post transform vertex cache. I don't clip each triangle on its own but accumulate some triangles an...

AFAIK Quake 1 uses s-buffer rendering for the scene and while doing so also writes the depth values which are then going to be used by the z-buffer rendering of the characters. I believe complex per pixel operations or deffered shading would slow down the rendering too much. Quake 1 runs fairly...

Could use a donated F200 too.

Yeah, I think a page which lists all the available libraries would be great. I would be happy if someone used my software renderer or my framework for the 940.

What's your problem with C++?

Hi! Some time ago I developed and released the cmd940 framework which would make it very easy to utilize the second CPU on the GP2X. I also had another thread about it on this board. cmd940 can be found on my homepage (look at my signature). I wanted to know if anyone is already using it...

Ok, I still have to test this code with my software renderer to see if it makes things noticeably faster. But for now I created a very cleaned up version of the code (warning: not tested yet). CODE #define MEMTIMEX0 0x3802 #define MEMTIMEX1 0x3804 union memtimex0_t { struct {...
