[Atari800-users] Mapping Arrow Keys

[Craig S. <cra...@gm...>]

Dear Support Team,

I have utilized the atari800 emulator in the past on my Linux machine
mainly to play and work with BASIC programs.  However, I was trying to play
some games as well from the Atari Mania site.  I don't have a joystick, so
I am dependent upon using my keyboard.  In reviewing the atari800.cfg file
and reviewing the "akey.h" file for key definitions, I was attempting to
switch the keyboard mapping from the arrow keys that are a part of the
number pad and directly use the "up/down/right/left" arrow keys on my
keyboard.  In the configuration file, there are definition lines such as
the following that map the number pad for joystick #0:

SDL2_JOY_0_LEFT=1073741916

I made some guesses as to how that value needed to be changed in order to
directly use the arrow keys, but I kept coming up with an incorrect
outcome.  Basically, I would like to revise these file entries in the
following manner:

SDL2_JOY_0_LEFT=<left-arrow key signal value>
SDL2_JOY_0_RIGHT=<right-arrow key signal value>
SDL2_JOY_0_UP=<up-arrow key signal value>
SDL2_JOY_0_DOWN=<down-arrow key signal value>

Any guidance or assistance in this matter would be appreciated.

Regards,

Craig
