I was actually privately asked about this a few months back (and forgot to check my PMs, oops!). I saw this and figured I might as well throw my work out there! A couple months ago I set out to make a Coder's cable with little hardware knowledge. I didn't want to internally mod my Dreamcast, but in...

I compiled the main part with only one or two warnings in the bios part. Like pointer but I need to look more closely after. I deleted the sound part, I have to rewrite it for the new version of kos. I didn't look at the graphics part yet, I need to remove the SDL and look at the loading file part t...

For testing homebrew with SDCard, I use isomake (2.4) from dreamshell directly. You can make iso from scramble/unscramble bin with Create_homebrew_ISO.bat / Create_katana_ISO.bat Can't try it now because don"t have SD here but it's working. http://www.dc-swat.ru/page/dreamshell/ You have the co...

Can you try adding this to see if something is on screen : : bfont_draw_str(vram_s + 32, 640, 0, "Hello"); You have printf value in your loading function. If you can't see this debug info on real hardware, can you put the value in temporary variable and show them with bfont_draw_str... May...

Hi, I search a code source version of openbor for Dreamcast. I have an old kos version for testing. I think it's good for source code close to v3.0 37XX. I only found a svn version build 4437 but this one is already deprecated for DC, so I have error with the malloc version of old version of KOS. I ...

Thanks.

I'm a little silly, I changed the little/big endian between the byte instead of the word. 0xAR,0xGB => 0xRA,0xBG

Now, that's works better.

Hi, I'm writing my owns tool for converting picture. I've some problems with the palette of the vmu save icon. I have an array of Hex value : const unsigned char vmu_bios_save_icon[544] ={ //Palette 0xF2,0x24,0xF5,0x45,0xF2,0x2C,0xFA,0xBB, 0xF0,0x9F,0xF2,0x01,0xF5,0x68,0xF9,0xAD, 0xFE,0xEE,0xFF,0xFF...

Thanks, I tried with this picture. 16 colors png. texconv -i damier.png -o damier4bit.dtex -f PAL4BPP -c -v With the verbose, I have : Loaded image "damier.png" Palette contains 16 colors RLE completed in 3 ms RLE result: 16384 => 338 Split 1 done. Codes: 2 Split 2 done. Codes: 4 Split 3 d...

I have tried a another code found here (https://github.com/Light-Dark/dcvqtex/tree/master/tvspelsfreak) and I have the same error. Maybe that comes from my executable version of texconv. Can commercial version of texture packer (https://www.codeandweb.com/texturepacker) compress palette file for Dre...

OK, what software do you use for compress your pictures and does your software can compress 4bit files ?

I have made others tests with a rgb565 texture. texconv.exe -i romdisk_boot/damier.png -o romdisk_boot/damier.dtex -f RGB565 I use this code to load texture in pvr : unsigned short * image_data; pvr_ptr_t texture_pointer; int width, height; FILE *image_file = NULL; image_file = fopen("/rd/damie...

I post my project with only the "load / draw" image part.

I use this for converting : https://www.dropbox.com/s/ry276pr79hvmp ... it.7z?dl=0

Thanks. That's a good news.

I tried with the VQ flag without success. I have the same result.
I tried with a new fresh compilation of texconv with linux, the hex file is identical and it doesn't work.

Hi, I use texconv to create my 8bit/4bit palette file. But I can't draw them with the "-c --compress" option. I use a 512x512 pixels images in 4bit. I have a size of 128ko and when I use "-c", only 20ko. You can see on this picture : the original non compressed on left and compre...

Hey, I don't know what libGL version you're using, but you might wanna toy with Kazade's version, as he's actively working on it. Also, I think I remember reading that lighting is currently busted on some libGL build. That might be the slowdown? I use the "official" at cadcdev/kallistios ...

The concept of VBO does not exist on the consoles of 6th generations (apart perhaps on XBOX). But the default dreamcast has a vertex buffer, the normal ones are not registered in it (the calculations are done only on the CPU side). And the textures are already in vram. The only way to gain speed in...

I don't know for the kos-objcopy error, but you only need 1ST_READ.bin after the conversion to use with bootdreams.

I found information on web, I need to put "texture, vertex and normal position of object" in the GPU to gain speed (not reload object every frame). It's called VBO. It's working like loading texture with glBindBuffer, glGenBuffers but I didn't find any example. Does someone has an example ...

I have made some test and the framerate fall down to 30 fps. [update ] I can draw nearly 3000 triangles at 60fps. With/without texture. Not so bad, but I think we can draw more than that. I used pvr_stats_t for showing the fps : sprintf(tmp, "frame rate: %f fps last_time: %f\n", (double)st...

I'd love to have this!

Look good man!

Why not, but first need to learn OpenGL
