GB Tile Editor

GB Tile Editor is a small tile editing tool for GB Compo 2025,developing completely in assembly.It's can also be used to create pixel art.

(and that's my first gb homebrew project)

Usage:

• When selecting tile:
  • D-pad:move cursor
  • A:select tile
  • Start:copy tile
  • Select:paste tile
• When editing tile:
  • D-pad:move cursor
  • Select+A/B:Choose color of A/B
  • A/B:Draw pixel
  • Start:Clear/Save/Quit

This tool is made for Game Boy,but you can also using it with emulators on different platforms.

Feel free to report bugs and advice below,and I'm waiting your art works made with this!

(NOTE:This tool might be too similar with On-Board GB Tile Creator because I didn't know it until the end of developing work.Still,I think there's differences between it and this tool.)
