EXTRA BG MAKER:Does anyone have this tool for Downlod?

[Ian Micheal]

I uploaded it for you nice you found a site with it to. none of this really can be done with out knowing a bit of coding.

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

yes!

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

Do I use PVRViewer tool to make PVR?

[mrneo240]

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...

Thank you could not find that anywere

Using malloc without free? smh...
