As an experiment I ordered a 21 pin mod board for lan kwei. I chose the Speedpost option. Board arrived in 10 days. Took 10 minutes to install. made some copies of my games. They all booted fine. Speedpost delivery to Phoenix AZ w/lense extension cable was $26.
ordered a mod chip a while ago, took about two weeks or less to arrive. connected the a and b points so i didnt have to hook it up to the chip on the saturn, works fine. i'm happy. i'll post back if/when it breaks.
