## rgbds doesn't let you set the game boy compatability
## flag at $0143 to DMG only so we pad the title to 16 chars long
## and the last char has a zero on the high bit which sets the rom
## to DMG only mode

## rgbasm:  -i ../ let's it find hardware.inc
## rgblink: -p 0xFF pads unused space with 0xFF
##          -t makes the game a 32KB ROM only game
## rgbfix:  -v put the nintendo logo in and fix the checksum
##          -p 0xFF pads
##          -m 0x00 set the MBC type to ROM only
##          -r 0x00 set the RAM (saved game usage to zero)

## padding with 0xFF is easier on flash carts and can trigger a RST
## file should be 32KB, if not it's too big and you need to use MBCs
