// ScummVM - Scumm Interpreter
// PocketSCUMM - PocketPC port of ScummVM. Based on the original Win32
// implementation by Ludvig Strigeus.
// Ported by Vasyl Tsvirkunov (vasyl@pacbell.net).
// Note: this is the very first version, implementing only basic functionality.
// Keyboard is not implemented, there is no way to access save/load game
// and the interpreter is hardcoded to one game (MI1 in this case). Later
// versions will get these limitations removed. Right now you should
// consider this port a proof of concept.
// To run PocketSCUMM, put PocketSCUMM.exe and game resources (MONKEY.000, MONKEY.001)
// in one folder (can be on storage card) and run the executable. Unused part of
// the screen below the image is split to two halves - tap on the left to press
// Escape (skip intro, etc.), tap on the right to change screen rotation.
