Hi ya'll figured I had enough stuff to actually make one of these threads, even though I am missing quite a few of my most wanted carts and a few GBA's.
Wow Ozito, incredible GBM collection! Also I am not interested in selling the OG GBA.
Nice collection. I've got one of those EFA Linker carts too, and it really is the forgotten gem in GBA flashcarts IMHO. Awesome compatibility, RTC, dead reliable. Not much capacity, but I only play a couple games at a time anyway.
If you ever have read/write failures with it, clean the micro-usb port on the cart and your cable terminals with some electronics contact cleaner. (available at Radio Shack)
