Okay, so I modified the original V26.09a navboot file so that it has the OEM splash logo. I made sure that the original file and the new file were identical. Next, using my hex editor I did a "CRC16/32 of file/block" calculation on the original and modified files and surprisingly they return identical values.

Next step is to slow burn the image using DVD Decrypter (preference thing, I hate Alcohol120%) I'll save that for tomorrow, kinda tired

Keep my fingers crossed. Not quite there yet folks, you gotta hand it to the X5World braintrust
