Soldering is not a big problem for me, but it's hard to find fake memory stick card.

I have only 1 MSPD - geniune sandisk 4GB (black body).
My friend has a old fake "sony" memory stick 4GB card with magicgate unknown, but I didn't open it.
In my opinion the most possible way with s1mp3: take nand from card to s1mp3. make a backup, change serial number and MSID by hex editor, write it to mp3 again and solder nand to fake card. (but I'm not sure if this player can handle 4GB nand).

I think it may works, but I don't know what's the real difference between HY27UH08*G2M and HY27UH08*G5M chips (mp3 has a G2M chip :/)
