The Korean 220v adapter is alright with our Malaysian 240v, cause the voltages accepted is usually 220v - 240v, and our Malaysia electricity hovers at around averagely 230v.

There's no need to use a poorly made 3rd party adapter.
Use the Original one~!

I assure you, that it can work..
If it doesn't work, it would've exploded when you plugged it in the 1st time.

I didn't know you were concern about the frequency,
but to assure you again..
Most if not all 220-240v adapters supports 50/60hz AC electric.

I forgot to mention, that even if the the 50/60hz frequency matters, it only matters to sensitive Lab equipments/machinery.
And the Wii is not designed as a sensitive equipment, its a gaming console for a normal non-professional home.
