+```json
+  "ResponseData": [

+reward0.item = 21
+reward0.item_num = 3
+reward0.trophy_num = 2
+reward0.music = 0
+reward0.navigator = 0 
+```
+
+File name starts with `telop` is the scrolling banner, it's just a plain text file with banner content.
+
+Other files like `news`, `option` and `cap` should also be possible, but I have not tested these.

 # Missing functions
 
-- [ ] Item/coin comsuming 
+- [ ] Item/coin consuming 
 - [ ] Unlocking system (I don't like these two so I just hardcode them, if you are interested you can implement that and add a switch to enable, PRs are welcome)
 - [ ] Ranking system (Is this really needed for a local server?) 
 - [ ] Proper update check response (Now it will just throw 404)
 - [ ] PlayInfo.php (Now it will just throw 404, I don't know what data it expext)
+- [ ] Online matching (and online matching events)
