I wasn't impressed and alot of others aren't either. The genesis collection is great though especially for the $ and metal slug anthology isn't bad either other than slowdown
I have it and I don't find it all that bad either. It would have been nice to have Robotron and Smash TV on it but I like it. It doesn't get anywhere near the play that my Capcom collections do.
I have not run into any problems with this game (of course I play mine right off my memory card wich speeds things up considerably don't have to worry about slow load times) but...
I do have the crappy PSP blurry screen.
