Installation

Unzip smsppsp.zip into /PSP/GAME/ folder on the memory stick. This should create the following directory tree:
PSP/
GAME/
SMSPPSP/
ROMS/ (game roms)
SCREENS/ (screenshots)
SAVEDATA/ (save states and SRAM)
BUTTONS.CNF (Button configuration file)
[any other files]
SMSPPSP%/
EBOOT.PBP

Game ROM's may reside anywhere (the ROMS subdirectory is recommended, but not necessary). SMS+ PSP supports ROM loading from ZIP files.
Controls

The emulator currently "ships" with the following default key mappings:
During emulation:
Analog stick - Directional pad up/down/left/right
Directional pad - Directional pad up/down/left/right
? (square) - Button 2
? (cross) - Button 1
? (circle) - Spacebar
L + R - Return to the emulator menu
START - Pause/Start

By default, button configuration changes are not retained after button mapping is modified. To save changes, press Ο (circle) after desired mapping is configured. To load the default mapping press ? (triangle).
Compiling

Emulator's source code is only available via a Subversion (SVN) repository. To check out a particular version, run

svn co http://svn.akop.org/...smsplus/version

where version is the release version (for example, 1.2.1). Note that for this to work, you need to have Subversion installed.
To compile the emulator, you will need zlib (svn://) and libpng (svn://).
