Type 1 is, boot menuhax only if this specific key combination is held
Type 2 is, boot menuhax only if this specific key combination is not held.
For example if you select Type 1 and only touch the bottom screen, it will boot menuhax if you don't press anything while it powers on, but if you hold down any button, it will abord and boot home menu normally.
If you select Type 2, let's say you set it to R like I have, it will boot menuhax automatically everytime and will only load the regular home menu if you hold R on startup.
