I'm aiming to use a 900-song collection of songs ranging from DDR (the first one) through DDR Extreme, as well as ITG 1-3 and Rebirth, plus 80 custom songs and charts that I've collected. This would be running via OpenITG, MDawg's ITG2 build via stepmania, or just through StepMania. I'm not really certain whether OpenITG or MDawg's build will do what I need it to do (I need adjustable life and judgment difficulty for a couple of the tournaments)
The doubles tournament may wind up running on DDR Max2 homeversion, and a couple of the other tournaments may use homeversions. I only have 1 computer available at this point and one USB adaptor (the pads we have are PS2 natively), so in order to run everything I might have to use PS2 versions. As far as which PS2 homeversions we'll have available, we should have DDR Max, DDR Max2, DDR Extreme, DDR Extreme2, ITG, and DDR SuperNOVA.
