try gamemaster in rowlett. I know they used to sell boot disks so Im sure they might be able to get a hold on some modchips for u. also try pop kulture in addison not really a gamer place but they do have some no region players so maybe they can do that there as well. Oh yeah there was also a place in valley view mall. used to have a sign that they can install mod chips for u there. I dunno if that store still there but it looks like an arcade also. lots of jland gaming there. somewhere downstairs.
The current PS2 chips like DMS4 are still 17+ wires that need to be soldered and the majority of the points are needle point (very small). Very time consuming and a pain in the a$$. I would offer but don't ever want to touch a PS2 mod again. Good luck finding someone that will do this MOD for you.
