Under the microscope: Tom and Jerry in "Fists of Furry" (Nintendo 64)
Shouldn't it be "fists of fur?"
Tom and Jerry in “Fists of Furry” is 3D fighting game in the style of Power Stone. You play as a member of the Tom and Jerry cast and your goal is to beat the snot out a series of opponents.
You unlock a bonus each time you finish a character’s single player mode. Once you’ve finished them all, you get access to a cheat menu. But what if you didn’t have to do that?
The “unlock everything” cheat
I found a cheat code that doesn’t seem to have been reported before. At the main menu, enter this sequence:
A, B, L, R, ZYou’ll see a Teamplay Mode item appear:
All characters will be unlocked:
And the Cheats item will be available in the Options menu:
Technical details
The function at 80068cf0 listens for input during the opening logo sequence and at the main menu.
It has a section that looks like this (pseudo-Python adapted from Ghidra’s decompliation):
if cheat_tracker == 0x0000:
cheat_tracker = 0x8000 if (pressed_button == A_BUTTON) else 0x0000
elif cheat_tracker == 0x8000:
cheat_tracker = 0x4000 if (pressed_button == B_BUTTON) else 0x0000
elif cheat_tracker == 0x4000:
cheat_tracker = 0x0020 if (pressed_button == L_BUTTON) else 0x0000
elif cheat_tracker == 0x0020:
cheat_tracker = 0x0010 if (pressed_button == R_BUTTON) else 0x0000If you input the sequence before the main menu, you don’t need to press Z — the effects will already be visible.
The Cutting Room Floor has information about a debug menu in this game. I didn’t see any way to activate it with a button code — alas!
TCRF also mentions that some of the menu code from this game is re-used in The Powerpuff Girls: Chemical X-Traction. I checked to see if it had the cheat handling code, but it seems to have been removed.
There’s a simple way to make the Tom and Jerry cheats show up in that game, however: set the address at 800bcb02 to 000f:
The code for these games resembles that for Earthworm Jim 64, but it doesn’t have this menu.
