lol i'm trying to get 25 of those as well, so i need to get 20 more lol...
sadly those maximum drive slots doesn't work like a maximum drive slot lol, when you insert a DX gaia memory, it won't play the maximum drive start up sound. also the button on it can't be pressed at all, it's just modeled all together. a little modding will fix those problems, then again since i'm gonna be using it for cosplay use, i'll only need to modify one, and that's gonna be for the Eternal Edge.
