Does anyone know how to reset the properties of the game so that the last Nemesis drop will be an AR instead of the infinite ammo?

Only New Game will get you AR. New Game+ his last drop will always be IAmno.

Yeah, I'm not sure how to get it to be a New Game though - the flag for "NG+" seems to be set or saved somewhere else, so that when I pick new game on arrange mode I'll end up with the infinite drop.

Ah, idk about Arrange, once I play only Original. Maybe it is impossible there.

In 'config.ini' I was able to find the multiple DataXX lines that seem to be based on progression (Data00, Data01, etc.). I just found out about this, so I haven't gotten the time to test everything. However what I do know is the what the following lines do:

Data00 = Mercenaries Cash (Set this to whatever amount of cash you need) Data01 = Infinite Assault Rifle (0 to disable, 8 to enable) Data02 = Infinite Gattling Gun (0 to disable, 7 to enable) Data03 = Infinite Rocket Launcher (0 to disable, 6 to enable) Data04 = Infinite Ammo (0 to disable, 9 to enable) Data10 = Game Instructions (0 to have them as items, over 1 to have them as files) Data11 = Epilogue (Number is the amount of Epilogue screens available, with 8 being all of them)

I do not have a grand understanding of this game. But my guesses are it's either one of the other DataXX lines that when set at 0 sets the game as a first playthrough, or setting Data11 = 0 will make the game think it's the first playthrough. If I got the time I'll experiment with it, but if someone can beat me to it then be my guest.
