Inserting custom music into a Mario's Picross ROM

Requirements

• A Mario's Picross ROM
• A hex editor

Instructions

1. Open the built ROM with your custom music in a hex editor and copy everything from address 0x4000 to the end of the file.
2. Open your Mario's Picross ROM in a hex editor and navigate to address 0x3C000. This is where the sound driver is located in a vanilla Mario's Picross ROM.
3. Paste the copied data from the built ROM in your Mario's Picross ROM at address 0x3C000, overwriting what was already there.
