I just realise we can convert our Wii to different region, but would like to have more info before i go forward with the conversion: 1.Is there any disadvantage for changing a Wiikeyed 3.2J Wii to US 3.2U/3.3U/4.0U? Does the system format the whole wii or just convert to US? 2.Will the Japanese Channels I downloaded still there, or will be removed/changed to US channels? Will I be able to access them if they remain? 3.Will I be accessing US contents or still Japan? Will I be getting US weather/wiichannel/wiistore and spending USD or still using Japanese content? 4.Will my save games be wiped out after the conversion? 5.Current latest firmware is 4.0U, will it cause any problem if i update to 3.3U or 4.0U? Is it possible to just upgrade till 3.2U via wi-fi? I have twilight hack installed and working, I found a few step by step conversion process but hope someone here could post a detailed step by step, like which software is best to do the job, i.e regionchanger etc.
