Well if money is not an option, this is the only place I've seen that still sells GBA flash carts with RTC in them.

Kind of pricey though, and I have no idea how good they are or if they're well supported. You should check the buy/sell part of this...
I picked up an EZ Flash III recently as well. I managed to get it working using my iMac and virtualbox to run XP. All I had to do was set up virtualbox to see the USB port and the writing device, and it's worked perfectly.
I personally handled a call from the second highest person at Raytheon. That call bothered me a lot... The guy was nice and smart what bothered me was the way management basically just blew him off instead of going the extra mile to help him.
In the end that call ended up costing Dell millions in lost contracts with Raytheon, and really the issue could have been solved for like 450 bucks lol
I always thought that capcom shuffled the games in these collection, but apparently they are all in chronological order, which makes legacy collection 2 worthless
