For everyone who wants to Screenshot with X360 GUIDE outside big-picture mode

[Frozenstar]

Steam disallows controller binding for screenshot outside big picture mode.
For people like me, who plays on PC with a controller but wish to use PC as a PC not a mere console, this can be really annoying at times, especially when big-picture mode is not at its prime time.
What I need is simply to be able to screenshot with the GUIDE button.
Why do i have to use GUIDE? because games use other buttons.

Some dudes suggest using Pinnacle Game Profiler, no way, too bloated for a simple purpose.
Joy2key? No support for GUIDE
Xpadder? You are joking.
Rejoystick? I'm waiting for your success report.
Joysticker? This conversation is over.

Back to topic, what i did was to take a crash course into AutoHotKey, learnt a few stuffs and made a minimal script that faithfully maps X360 GUIDE to F12 (both down and up states are captured)
Different from Big picture mode, this program uses GUIDE not GUIDE+RT. Because games use RT. I have no way to prevent games from reading RT state during screenshoting.
