Figured I'd pass along the news for anyone here interested in immortalizing your Dreamcast with a ODE.
GDEmus will go on sale again Saturday at 11:00 CET ( Central European Time)https://gdemu.wordpress.com/ordering/ordering-gdemu/
They may sell out fast to set your alarms and show up early.
Alternatively USB-GDroms are in large stock and available now.http://3do-renovation.ru/How_to_buy.htm
Both are great products, just depends on the interface you like and media you wish to use.
