Its not, i agree with that.
But again, if the R4i team actually tested the firmware they would have run into this problem and the firmware would've never been released.
So i still say the R4i team deserves the blame for this happening. since they're the ones copying and pasting, and deceiving their customers.
Gateway didnt deceive their customers, since their launcher works perfectly fine.
They dont have to guarantee that their code works if modified. Thats on the R4i team to guarantee.
There's a slight problem man , that this method of protection is NUTS because it can affect MORE than clones
Imagine that you have an old sd and upon copying the launcher dat to your sd something gets changed , a slight change if you want , but something changes. This checksum checker goes on and BAM , you're dead
