Well, there is still the real Minecraft on Pandora, so i think whe just need a Pyra Port to have it also on Pyra..
no need for the Rapi Edition
i dotnt have experience whit Minecraft on the Pandora as i have the slow CC Unit but it should work werry well on Rebirth and 1ghz Pandorae, so at Pyra it shall need some break to not run too fast..
