SD v2.2 interface

I ran the page from sharksym through google translator and found out that he is working on a new bios. It is not finished yet.

For those who cannot read Korean (like my self)

First version of the FAQ is online. Have a look here: http://members.quicknet.nl/evanson/Page/MMC/faq.html

Good to hear, do you like the SMD dac on it? it works pretty well and is very tiny.
Hope you enjoy it!

It works exactly as you think. I use 2Gb cards with only 256. Hope that sharksym releases his new bios soon then we can use full capacity up to 2Gb
Soldering was quite easy. The cpld is harder to do

The SD v2.2 has no SCC chip included. Sinfox is selling v2.2 with SCC chip.
I have a version 1.0 with SCC but we need to butcher old games for SCC chips or find another source for the SCC chips.
Or I can make one from an old konami cart using a small cpld to make a new one.
If you can supply a donor cart then I can turn that one into at least v1.0 and maybe into v2.x also.
Need to look into that again
