Super Mario Bros. Two Player Hack Editing

About this project

This is a moderately detailed description of some of the tricks hackers might need to know when making hacks of Corpse Grinder's Super Mario Bros. Two Player Hack.

It contains a short explanation of Luigi's color pallette, some of the enemy color pallettes, and a detailed description of how to edit the Title Screen (including locations of each row and column in the Title Screen box).

Hope this helps any hacker out there who's daunted by the prospect of making their own Co-Op hack and getting everything right!

*** This is all just stuff I have learned from my own experimentation and testing with the 
hack, it may not all be completely accurate and is subject to change.



- Luigi's Pallettes are now tied to the pallettes of some of the enemies and objects (namely 
things like Overworld Koopas and the Fire Flower), and the same goes for Fire Luigi (tied to 
the pallettes of things like the powerup Mushroom and Red Koopas).

- Goomba and some Overworld enemy pallettes are now tied together as well, including enemies 
like the Buzzy Beetle and the Bullet Bill.
