Do these backgrounds show up automatically once they are on the vmu?

your best bet is to not encode directly 565 but instead rgb565 vq4 with no mips

256x256 can be still fairly small

example of my usual 0GDTEX.PVR

if you want the image to be oriented correctly on the bottom plane, feel free to flip

i like pvrconv ".\pvrconv.exe -gi 666 -v4a -nvm -f .\neodc.bmp" would work great

In case someone is looking for the Gimp plugin that was mentioned on the first page of the topic, I dug it up off of the KOS website. You can find it here: http://gamedev.allusion.net/random/gimp ... -16.tar.gz

It probably won't be of much help at all, but I figured I'd mention it for completeness...

Code: Select all

Código:

   // copia o cabeçalho do PVRT

   memmove (p, PVRT_HEADER, sizeof (PVRT_HEADER));

       * p ++ = (nRGB565 e 0xFF);
       * p ++ = ((nRGB565 >> 8) e 0xFF);

}


Using malloc without free? smh...
