We were once excited for Cash Money Guns Chaos, but it appears our hopes were for naught. IGN reviewed the PLAYSTATION 3 version of Cash Guns Chaos and they don't have very nice things to say: "Smash TV worked because it constantly switched up enemy and power-up types in quick 30-second rooms that would branch out into all-new areas immediately afterward. But Cash Guns Chaos doesn't do that."
There might be hope for the PSP version, but I doubt it. Considering how this is one of the first games that will let you play PSP versus PS3, I had much higher hopes for it.
