Unable to set multitap from frontend

[GoogleCodeExporter]

What steps will reproduce the problem?
1.using a front end on yellow dog linux I am unable to click multitap 
2.
3.

What is the expected output? What do you see instead?
command line force multitap, or editable shortcut to enable multitap I can set 
to a controller

What version of the product are you using? On what operating system?
yellow dog linux, its an older version 65 I think

Please provide any additional information below.
i have not updated since I have seen nothing in the changelogs addressing this 
issue. While using zerogame front end via ps3 and dualshock 3 controller there 
is no way for me to enable multitap. If I could map L2 to enable multitap or 
even force multitap via command line I can play 4 player without needing a 
keyboard to turn on multitap
