Problems With Marvel vs Capcom2 usa: internet disabled
 

I beleive it' was disabled through the 1st_read.bin
because all of the dreamcast passport files are intact i hacked the magio.bin next to this hex code (96 9e 03 66 6a) changed the <6e b0> to <5a 2e>,2_dp.bin near this hexcode (43 44 30 30 31) changed from <a6 00> <5a 2e> and the SG_dpldr.bin near this hex code (00 00 76 93) <6e b0> changed to <5a 2e> this method works with all my internet games not selfbooting. I think Kalisto disabled this through the 1st_read.bin because sonic adventure was fixed replacing the 1st_read.bin and Replacing the dreamcast passport bins. but how do i fix the 1st_read.bin for marvel vs capcom2 usa and enable the internet option ?????
