i like motionplus but i dont like grand slam tennis (i play at home). virtua tennis seems better. i was lucky enough to try it for 5 minutes at mediamarkt.
i heard the exact same thing so I created a fat32 partition using paragon partition manager then i formatted wbfs using pc. i hook it up before opening wii and there is no problem. i set 'sleep mod time' to never using seagate tool and it never caused me a problem.
