hmm... my guess is:
the crc check, after completing, changes a couple of bytes in those memory addresses and then a check for those addresses is made. If the value is false, (0) the game continues, if it's true (0) it jumps to MSOD...
am I right?
I've been trying this code for 62 minutes till now, and no MSoD till now...
using a R4
can we now know what the hell this code does? I'm pretty curious
But... if Squarenix really developed such an anti-piracy system aiming particularly at cartdridges that patch the roms, it means that some of their staff studied how the most famous cartdridge such as R4 works.... they're probably also reading this same thread as guests (and laugh maniacally)...
