Oh no, Oh no, Oh no, Oh no, Oh no, Oh no, Oh no, Oh no,

Okay I did a stupid mistake. I pulled out the ROMs and dumped them all EXCEPT for the printer ROM. I plugged them all back in and I accidentally plugged the printer ROM backward. Upon powering I got a weird screen after some looking around I found that it was inserted the wrong way.

I took it out and the device powered up fine, but upon inspection of the data, it was all corrupted!
Does someone know where I can find a replacement. It was the printer ROM and it had the number 160-5531-01 PRINTER.
I really messed up and I'm doubting that I will find a replacement file on the internet.
HELP!
