Mario Tennis - All Nintendo Characters Unlocked

Hack of Mario Tennis


Mario Tennis is a fun portable tennis experience, but, despite him being in the title, the game does not even let you play with Mario from the beginning! It also has nearly half the roster locked behind antique DLC mechanics as you need a transfer pak and both the GBC version of Mario Tennis and the N64 version of Mario Tennis to unlock all Nintendo characters.

This hack will make all Nintendo characters available from the start of the game.

It is to be noted that this hack does not make any changes to your save file, so you could still go through the steps that would unlock Mario and Peach and retaining this progress (as well as other progress data) when switching back to an unpatched rom.

This patch has only been tested with the USA rom but should work with the European rom as the roms are identical except for some minor bytes.

Note: Warehouse Court unlocks after beating all the other Mario characters with a Mario Character.
