PS3 Controller in PS3 Linux

[RetroGamer]

Is the PS3 Controller supported in Gentoo at all? I haven't installed Gentoo yet, and I don't want to bother if it doesn't support the PS3 [yet].

[jimparis]

The SIXAXIS works as a USB HID device when attached via USB; it does not work via bluetooth, nor does the motion sensing work. Both should come someday.

The following is a patch for the debian linux kernel 2.6.18
Using the wiki on the main page at ps2dev.org to install
gentoo, is the following patch needed? or do you just plug it
in and it should work without patching? is there a joystick test
utility the you can emerge in gentoo to verify that the joystick
works? and how about some code that can capture input?

The PS3 Linux kernel already has the required patches. It is a standard joystick device, there's nothing special that needs to be done. http://gentoo-wiki.com/HOWTO_Joystick_Setup

[RetroGamer]

Is there a way to map a keyboard's keys to the PS3 Controller in Linux. I want to run an N64 Emulator and play all the old roms of games I used to have using a more 'familiar' controller than using a keyboard. Any ideas?

[jimparis]

That would require either that the emulator you're running has joystick support, or use of a tool to translate joystick to keyboard input. According to Google there are many tools that can do that: qjoypad, gizmod, joy2key..

[RetroGamer]

I like what I hear, I'll look into that!

[J.F.]

QJoypad is my favorite. Works great with Playstation controllers (in my case, I use it with a dual-shock in Fedora Core on a regular PC).

[pseudonimo]

Seems like it's possible now: http://www.pabr.org/sixlinux/sixlinux.en.html
