QUOTE(headspin via gbadev)For those having trouble Warhawk DS v1.02 is now released along with some minor changes and improvements. The FAT version is now pure FAT (not running through EFS) so it might help some people.
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
