A webapp for editing FCH character save games, which are used by the game Valheim.
It supports editing the character’s appearance, name, inventory, buffs, skills, and unlocked map. It also supports importing/exporting characters to/from JSON files.
Written in Vue 3 and TypeScript, using tests for correct reverse-engineered save file parsing. I had to reverse-engineer the save file format myself, as there was no documentation available at the time.
After I released this, the updates to the game later on broke the save file format, and I did not continue updating the tool.
