Hi,
I sent my 2 CPS boards to RAZ, a Japanese SF Zero 2, and a US X-Men COTA. Got the ROMs back within a week, and installed them.
Sadly I didn't remove the battery long enough before sticking the new ROMs in so it didn't work first time, but a quick e-mail to Raz, and he told me to short a couple of solder points & Boosh!
2 non-suicidy CPS boards!!
I'd def recommend him, and I will be sending any more CPS2 boards I get to him. Raz is da man
