This patch converts Nekketsu Koukou Dodgeball Bu (J).nes from Mapper 1 to Mapper 4 
so that it is possible to reproduce the game with a AX5202P chip. I didn't developed this patch, 
I just extracted it from a pirate multigame cartridge rom. Use it at your own risk. 
For applying the patch use Lunar IPS.exe and patch it over 
Nekketsu Koukou Dodgeball Bu (J).nes version of the game.
