Thanks for the responses and for clearing that up for me. You make great points!

So, I know that turbo/auto-fire and macros aren't allowed for runs, but are there any other rules about legal controllers to use for runs on certain platforms?

I believe some runners like to use controller adapters to do runs (e.g. using a Playstation controller on a Gamecube). The reason I'm curious is that I'd like to use something like a CronusMAX to use a keyboard with a PS3 to do some runs as using a keyboard feels better to me for the tank controls. However, I don't want to submit results if this is considered an unfair advantage.

Any thoughts or guidance on the matter would be greatly appreciated! :)

It sounds like a good idea to me if for no other reason than the new test layout appears to be much easier to navigate and filter.
