    Hi,

    My ps2 v4 acts oddly with backups. It can easily read original games and backups as well with swap method. No difficulties to read them, it's perfect.
    But when using ESR or a modchip, backups tend to launch every 10 tries. I don't understand why.

    My lens might be the problem, but why can I read original and swapped backup flawlessly?
    The DVD+R I'm using maybe? But, again, why swapping works flawlessly?

    Anyone have an idea?
