Mad Stalker Hi-Res mode?

[vestcoat]

In an old post, there was mention of a secret high resolution mode that can be unlocked in Mad Stalker.  Does anyone know how to do this?

I just got this game yesterday and it's totally boss.
i have seen complaining in the past about how the graphics could have been better and how there can't be very many enemies on screen at one time.
whatever, this game is great and i haven't even tried the VS mode yet.
