Add fix to prevent game from hanging

Currently, disabling ESYNC and FSYNC fixes the game from hanging after proceeding the in-game terminal menu by entering or clicking `search` . 

Additionally, the problem of ESYNC and FSYNC hanging appears to be present in other games using Nitro Plus' game engine such as Song of Saya (702050) and YOU and ME and HER: A Love Story (1293820). Up until now, those problems were never addressed upstream so these workarounds are necessary for the moment.
