Removing sbox patch

[leav]

hello everyone,
my friend has an external "sbox" usb mod chip.
he burnt the game "socom:navy seals" and it works fine for him.
i have an internal mod chip and i use a dvd region x to boot the games. as you might of gussed from the last line the game doesnt work on my console. i called up the store that assembled both my chip and his and they said that some games, not all, have a speacial patch on them allowing them only to be played on an sbox mod chip. my question is : is this true and if so where and how can i download the patch to make the game compatible with my console?
i hope SOMEone can help......
