Finally, a long needed update. I've sold some things, paired down a bit, but also bought some fun new items.
My current setup (pic taken months ago before Karous artwork applied to the DC):
Imports: Japanese and European games. Despite the console art, sadly no Karous yet, but I'm keeping an eye out for a good price. It's at the top of the list for remaining DC games I still plan to buy.
US games, most of which were purchased back in the day, 2001-2004.
Not pictured: recent acquisitions of US Mr. Driller and PAL Evil Twin, spare dreamcasts, many normal standard controllers/vmus/web browser discs etc
