Got this stuff today...
The Ant Commandos PS2 to PS3 converter. Works great with PS2 guitars on PS3 Rock Band and Guitar Hero 3. But is not as good as the Pelican converter (best one out there for PS1/PS2 arcade sticks on PS3) for fighting games. So after the sad testing session was done, I went to GameStop randomly... where I saw...
Holy crap, NEW for $9.99!? Don't mind if I do. I almost did a triple take. If you're familiar with these, you should know how much they go for on eBay. Yikes.
Here is a link to my review of the TAC PS2 to PS3 converter:http://sdtekken.com
Top article.NOTE: This review only pertains to the converter and it's use with fighting games.
Our guitar compatibility portion of the review is still being written. Should be up sometime soon.
