It's the PC version UTFBM-2.3.1-pc, I extracted the archive.rpa file
The names of the files and folders are not the same as what the game is looking for
I draw my own conclusion. I looked all over the issues and playtest everything. When you go to new game, it will force you one of two labels (chapter 1 and chapter 1_mobile). I made an if statement of "touch" screen enable or not.
I can only think that you have a pc that's automatically enable the touch support. If you have a touch inside your device, you'll be heading to chapter 1 mobile (with the mobile version categorized as) that is out of date. If not, then it will run naturally.
