Look at the right bytes for screenshot mode

Although, there's a bunch more needed to make this work properly.

It does happen that `100` = `0x64`, and `(0x64 & 7)` = `4`.  However, `4` does not have this behavior, neither does `0x80000064`.  Only `0x64` does.

Although actually, you have to change mode to 101 for it to quit.  102 makes it switch back to 2, but I don't know what to do then (probably wait and then issue another attempt?)

The above information required a ton of hard resets of my PSP, so I don't really want to mess with it much more atm... but this should be the right way to try to hack around the ContStart stuff.
