This is anti debugging protection, which shmoo made a tutorial about how to bypass.

Search for 'Syscall bypass' & you'll find the tutorial.

You need to research , there are several syscall functions .You need to find the one that calls 0x1F (31)

I hacked Six Guns & I don't think the syscall was diffrent from Shmoo's tutorial.
