Web-based, experimental savedata editor/viewer for Nintendo's Game Builder Garage

Status

Currently on hold due to lack of interest and an issue regarding file hashes that prevents games from being uploaded online.

Implemented:

• Full level file parser, reads metadata, textures, nodon, connections, etc
• Partial level file exporter
• Texture editor
• Nodon graph viewer (pretty basic, doesn't support ports or settings yet)
• 3d world viewer (also basic, doesn't map textures properly, doesn't support connectors or customised world lighting)

Screenshots

Game information view, also showing all the textures used:

Texture editor with various tools:

Basic Nodon graph view -- connection ports and settings aren't currently mapped, so not too useful:

3D world viewer, textures currently aren't quite mapped correctly in all directions:

glTF exporter so levels can be brought into other 3D software:

CLI

You can run parts of this tool from the command line to inspect files etc

Please don't submit PRs or issues yet, this code is going to change a lot as the project develops. If you're interested in helping reverse-engineer Game Builder Garage, you can find me on Twitter @rakujira, or on Discord @jaames#9860 -- I will likely post on Twitter when I feel like I've made enough progress for an announcement.
