Hacking Flash Cart That Supports Pokemon Colosseum/XD?

[ViewtifulV]

Hi, I've searched the forums but haven't found an answer to my question.

I've been using an X-Rom 512Mb and it works great. But I could never get it to work with Pokemon Colosseum or XD. After some research, I found out that the X-Rom uses sram to save while the the original Pokemon carts use flash, which is causing the problem. Since I doubt this problem can be solved with the X-Rom, I want to know of any currently available gba flash carts that work perfectly with Colosseum/XD.

Any help would be greatly appreciated.

I never tried it but I thought some people had gotten it to work but keeping the cable disconnected to the GBA and connecting it at a certain time while the game is booting up. Take a look at this post if you haven't already tried this:
