* Sample game: https://vndb.org/v22252: /HWN-8:-1C@233A54:yuika_t.exe
|

* Artikash 9/11/2018: This is more than just Tyranobuilder. It's actually a hook for the V8 JavaScript runtime
|
||||
* Sample game: https://www.freem.ne.jp/win/game/9672: /HQ8@2317A0:Prison.exe This new hook seems more reliable
|

* Issue with hook: many garbage text threads. Maybe use another split?
