It's been a while since I wrote this so I don't remember all the details, but I checked my zip file and the json is in the same directory as the RPG_RT files

I don't remember having to modify the index file. Aside from that, I used the default folder structure mentioned in the easyrpg guide. If I'm remembering right, after creating the json file I copy-pasted my project folder inside the "games" folder, renamed it to default, and then created the zip file
