; pl1Ak,pl1Lk,pl1Yk,pl1Bk,pl1Rk
; (Change 1 to 2,3,4 for other players)
; Each of these variables contains the corresponding key pressed value
; for the key data
; pressed[]
; - This is an array of pressed/released data (bytes) where the
; corresponding key pressed value is used as the index. The value
; for each entry is 0 for released and 1 for pressed. Also, when
; writing keyboard data to this array, be sure to first check if
; the value of the array entry is 2 or not. If it is 2, do not write 1
; to that array entry. (however, you can write 0 to it)
; As an example, to access Player 1 L button press data, it is
; done like : pressed[pl1Lk]
; The 3 character key description of that array entry is accessed by the
; GUI through ScanCodeListing[pl1Lk*3]
; Note: When storing the input device configuration of a dynamic input
; device system (ie. Win9x) rather than a static system (ie. Dos), it
; is best to store in the name of the device and relative button
; assignments in the configuration file, then convert it to ZSNES'
; numerical corresponding key format after reading from it. And then
; convert it back when writing to it back.

.SH "FILES AND DIRECTORIES"
.TP
ZSNES
The main program.
.TP
~/.zsnes
This is the directory where ZSNES configuration files are stored. By default, it is also the directory where save states, screenshots, SPC dumps and ZMV movie files are stored, but you can change this behaviour by editing zsnesl.cfg. This directory is created by ZSNES.
.TP
~/.zsnes/zsnesl.cfg
This file is where configuration settings for ZSNES are stored. It is in a human-readable format and can be edited by hand. It is created by ZSNES.
.TP
~/.zsnes/zmovie.cfg
This file is where settings specific to AVI dumping are saved. It is created by ZSNES.
.TP
~/.zsnes/zfont.txt
This file allows you to customize the fonts in the GUI. Enable "Use Custom Font" in the GUI Options menu. It is created by ZSNES.
.TP
~/.zsnes/zinput.cfg
This file is where input configuration settings for ZSNES are stored.
.B If for some reason you update your version of ZSNES and it keeps crashing before you can do anything, you should try deleting the above .cfg files and let ZSNES create new ones.
.SH "SPECIAL CHIP GAMES"
Many games on the Super Nintendo used custom CPUs in addition to the main SNES CPU. Some of these CPUs have not been fully reverse-engineered, and games that use them may either not work or may experience strange bugs.
You can find more information about these special CPUs at:
http://users.tpg.com.au/advlink/dsp/
http://nsrt.edgeemu.com/INFO/chipinfo.htm
.SH "GRAPHICS PACKS"
Some games based on the SPC7110 chip, such as Far East of Eden Zero, can use special graphics packs to work around unemulated portions of their custom CPU. These graphics packs must be stored in individual directories within the save directory, which is specified in zsnesl.cfg. By default, this is ~/.zsnes. The directory name of each graphics pack must be capitalized and all files within that directory must be in lowercase.
The proper directory name for a given graphics pack can be found in the readme file included with that pack.
NOTE: As of version 1.40, games which use the S-DD1 chip (Star Ocean and Street Fighter Alpha 2) do not require graphics packs.
.SH "REPORTING BUGS"
You can report bugs using the bug tracker at the ZSNES BountySource page, located at
