2. using my original suggestion it's not difficult. If it builds and runs it can be signed and dispersed. Even without it we can build our own app from source and throw it on the phone.
I could blame apple maybe for their phones not being "powerful enough", but again i find that hard to believe as it can run games far more visually and technically intensive. I don't know how PRO is built so i'm not fully aware of how they would have to port it over, but if it was done right I'm sure its possible, It just may not be feasible or worth it to the developers as it probably would require a rewrite in some aspects to optimize the game.
