God Eater 2

[hikaru702]

Well, I never tried the actual GE2 v1.4 (I just play GE2 v1.3 game using the given GE2 v1.4 emulator, just to benefit the no-restart), but by using common sense and a bit of reading, it looks like we can play GE2 v1.4.

You just need to prevent from bringing AIs into the mission. Which you can, by using either 2 ways:
1) Use the cheat code to disable AI (read the given instruction when using cheat). I somewhat don't recommend using this method since... I carelessly forgotten to re-check the cheat when starting GE2, causing my precious save files to be corrupted.
2) Bring 4 of your friends to play using PSP and/or PC (well, no one built and share the v1.4 emulator for android), so no matter if the mission requires an NPC, your friends will take that NPC position, legally disabling them. Neat, as they say~
