RA has the 4DO core but it is unplayable slow. There is another one “Phoenix” which is much faster. There is one on the Play store that is full speed on a Shield Portable! The problem with that one is that it has reoccurring online check-ins, not very convenient for the SP that is not online at all times.
It would be nice if RA had a playable 3DO without the annoying online DRM of the Play store version (I don’t mind buying, just the DRM, Boo! Hiss!). Could this Phoenix one be used instead of 4DO?
