Image 2 Graffiti (for Jet Set Radio Dreamcast)
Disclaimer : I didn't make this, I merely fixed 2 thing so I could use it on Linux Mint. Original webpage here : http://www.jumpstation.co.uk/dreamcast/ii2d.html
Run ./graf -image -vms
-image should be a jpeg -vms should be something like filename.p## ## = something between 00 and 99
I'm using Dreamshell to uplaod my files to my VMU
