Hello, I just had ordered a Ps2 modded with a messiah 4.0 chip, not sure what ver of it it is tho, i had a few questions, i have a sony DVD writter External DRX-500ULX. Which writes DVD+R & DVD-R, also have a DVD+R in a Dell note book, my main concern is which media to use as well as which is best to write games DVD+r or DVD-R? Sorry for so much, just a bit overwhelmed

Thank you for your time and effort
