Re: Building a SD card adapter

Hi Rob,

The mask [1] I sent you is reversed. The layout I just posted [2] is
not reversed. The SD card is inserted upside down, so on the reversed
mask pin 8 is to the left, and pins 1 and 9 are to the right. I've
posted a photo of the adapter [3] with an SD card inserted. I can see
scrape marks across the copper fingers where the GameCube's contacts
have made connection, so it looks like the contacts are in the right
place and at the right height.

Is any specific type or size of SD card required? My SD card is
labelled "SanDisk SD Card 32 MB".

Thanks for your help! Cheers,
Shaun
