In exercise 1, you will add a hat to Goombas only using existing sprites. To add a hat, we only need to edit 2 bytes in the game. It is your job to edit the IPS file so that the address and new data are correct. You will need to change the 5 bytes set to FF to correct values.
For exercise 2, have fun drawing out a new title screen using SMB Title Editor! When you’re done, make an IPS patch and send it in the Discord.
This can help with writing/understanding IPS files.
This is a great resource to read the SMB1 ROM file easier.
This is one of the most referenced video game hacking guides of all time. It is the bible of any aspiring ROM hacker.
