"I played it at Wondercon, and at least from my short time with it everything seemed to work exactly as it should. They even have fully customizable controls, thank God."
"Like I said, there is a custom control option that lets you map the buttons however you please. It was the first thing I checked for, because it drives me nuts when games have jump/shoot switched around from how I like it, which is my beef with GBA emulation on the DS in general."
Had a friend of mine confirmed this too, and according to him, the booth's Capcom rep mentioned the option applies to all four games. This should come as good news for those who'd prefer a setup reminiscent to the SNES style layout of the early X games. No complaints here!
On a related note, the aforementioned Capcom rep also commented on the game's release date, and despite a delay in Japan, the compilation is still on-track for a second quarter summer release. More details at Captivate 2010, hopefully.
