I know about Dodonpachi, I was at Gamestation at 9am waiting a few days ago when it came out lol Got Deathsmiles PAL too. I had considered a region change on a console then removing the exploit to go on xbox live but still cant get my head around if its detectable or not. I assume it probably is but if the consoles not flashed and currently exploited then I'm not sure its something they would be looking for. I'm happy paying for my games either by importing or GoD. I've got a few jtag exploitable RROD consoles lying around so might give it a go if I get one reflowed to fix the RROD.
