owner of xperia play, i had the n64oid 1.1.4 working more or less full speed. The 2.0 apk is a best match for compatibility, CONKER'S BAD FUR DAY and PAPER MARIO now working (not in 1.1.4), RAYMAN 2 still doesn', but on other hand, games working perfectly on 1.1.4 work now slowly (MARIO KART...), even changing to oldest plugin. Can't wait for 2.X apk for speed improve!!!!!!!!!!!!!!!!!!
