antiroC has released Ms Driller for the PSP, heres the info:
<blockquote>Here's a quick port of a Mr Driller clone, called Ms Driller.
Original game by Adas
Lower res graphics taken from the GP2X port by Kfazz
I have modified the controls a bit to try and compensate for the PSP's crappy diagonal movement handling, so the controls are:
Move: Analog or Dpad
Dig/Drill: Circle
You can also use the L & R shoulder buttons to jump up/left and up/right.
Only tested on 1.5 firmware and seems to work fine - should also work on 2.0 if someone wants to test it out....
Todo - make it higher res and improve the readability of the ingame text and possibly add some background music....
edit: changed controls info...</blockquote>
