How to Do HEX Editing in SNES ROMs

Hexadecimal, or Hex, is a computer language that lets users read the information of computer files and change any of the values. This in turn can change something in the file itself. Hex editing Super Nintendo (SNES) ROMS lets you change things inside the file, such as levels, colors and sprites.

Instructions

- 1
  Select a ROM of an SNES game that you already own. Download SNESEdit, the only Hex editor meant specifically for Hex editing SNES roms (See Resources).
- 2
  Click "Run" to open the file once it mounts on your desktop. Select "Install" to install SNESEdit.
- 3
  Open the Hex editor and select "Open" from the "File" menu. Select the SNES ROM you want to Hex edit from the list, then click "Open."
- 4
  Select "Search" from the Hex editor's menu and input the hexadecimal line you want to edit. Each ROM has different hexadecimal lines that represent different information inside the ROM. Click on the line and select "Replace" from the menu.
- 5
  Type in the new line of hexadecimal information and click "Save." Repeat this process with all the information you want to change inside the SNES ROM.
