-in the ...counter-strike scource\cstrike\cfg folder, copy the 'config' file and paste it in the same folder

//exec default.cfg
r_decal_cullsize 1
// Setup custom controller
exec joystick.cfg

exec autoexec.cfg
//
// stuff command line statements
//
stuffcmds
-make a new line after the 'stuffcmds' line
-type in:
//
//PsysBuyMenu
//
exec psysbuymenu
-after typing that in, the valve.rc file should say:
