Hi. I am about to install a solderless modchip on my xbox. I was about to go for Matrix until I found out that it only had half the size of the xecutetor 2's flash rom. How critical is the size of the rom? Did anyone using matrix encounter any problem because of the smaller memory size? Also, is Matrix chip capable of HDD upgrade? I looked at couple sites that sell matrix, but none of them states this chip supports HDD upgrade. Thanks in advance for your help.
