pinouts by Asdron also confirmed by RichDevX

About Pin 1: "it's an input pin on the host controller (pulled up high), and the pin on the card is grounded" (source RichDevX)

Soft Reversing

The OS driver for the Memory Card can be found here:

os0:kd/magicgate.skprx

But this will require a kernel exploit source to be able to dump this kernel driver and reverse / analyze it for future purpose which is right now not possible to do the lack of the source code for HENkaku.

HW Reversing

• Waveform of the memory card, planning to release the source code for the simple logic analyzer soon. PulseView is awesome :D picture

• Hmm, although it appears to be based on memory stick pro, looks like they may be using a different command set picture

• Here's the famous serial to parallel transition command (was it designed to look like a transformer E core on purpose? ^_^) picture
