I wanted to know if anyone has used the Toodles Cthulhu PC/PS3 Board I want to be able to use an arcade stick on the PS3 and Mame and this PCB looked like a viable option any help or opinions would help
I used two of them for my Virtua Stick Pro (Astro City) panel mod. They are very easy to use, and have zero lag, even on PS3. The only downsides are that there are a lot of wires to strip and on PC, it is recognized as a joystick rather than a keyboard. (Or, more accurately, a POV hat on a joystick). This is a bit more difficult to use than a keyboard type encoder because you can use some MAME defaults with boards like the IPac. Also, if you want to have a two player panel, you need two Cthulus, whereas with an Ipac (or any of the others) you usually only need one.
The Cthulu also doesn't support trackballs or spinners.
Long story short: if you want to build a MAME controller with all of the bells and whistles (like a trackball, spinner, multiple joysticks, etc.) use an Ipac or some other keyboard controller. If you only want to build a good joystick, the Cthulu is a better way to go. I used them on the Astro City panel because it doesn't have a spot for a trackball or spinner and I'm intending to use it for PS3 also, but my main MAME panel is built around an Ultimarc Ipac2.
