sniper Modchip doesn't work with GAP-Bios!

We need to get to a controlled situation to know what the chip is doing. Your options are:

1. Get a non-rip backup that is known to work elsewhere and try that
2. Get an import original and try that
3. Try your rip in a PS2 that is known to work with any modchip and rips

That should point to the answer. A naff rip is not out of the question.
