Pac-Man, Pac-Man and Rally X are currently near spot-on to their arcade counterparts. Only Galaga wasn't selectable, and Dig Dug was running just a little slower than the arcade game. We received an early-in-development version of the collection, which featured four of the five games completely playable. Oddly, all but Rally X have been available on the Game Boy Advance in previous Namco collections, which are still available on shelves for budget-style prices.
Unfortunately, the GBA compilation won't be as extensive as the console iterations, only featuring five games in one cartridge: Pac-Man, Ms. This new collection is being produced by the emulation nuts over at Digital Eclipse.
