Modchips and online compatibility

hello,

I have a modified v5 with Matrix MXL and I do not manage to pass DNAS test even while having turn off the modhip (by pressing reset 5 sec).

Indeed, on Destruction Derby Arena (beta), I obtain "error -613" and something of similar on "Hardware" (beta) too.
Warning, it is not a question of a "error -402" specific to "boot PS2".

Did somebody know the same problem (knowing that for US Socom Navy Seals it is understood there is no problem)?

Which is the result with others modchips such as Messiah2, Magic V, Mars II, Apple pro, etc...

Thank you to answers.
