i tried formatting my ds linker to firmware 1.39 that comes with Xmenu 2.42 and it asked me to restart so i did but when i opened the ds linker it says
loading menu
error: not format!
so i tried connecting the usb and it actually allows me to look at the options
usb mode
game mode
but...
But Nintendo's GBA video format is different, being that it uses a custom ROM and chipset for rendering, for like the Shrek and Shark Tale titles. Been undumpable for years and years.
