"About BwE NOR Validator:

This all in one validator/patcher will interpret the byte orientation, patch for 3.55 and will then output the results of 2400+ validations.

How to use:

Place your .bin/s in the same folder as the validator.
Run the validator and press Start.
A console will appear asking you to select your dump (if you have more than one in the folder).
Make your selection and or select if you watch to patch it (either in its current byte orientation or the opposite).
Wait patiently.
Press Enter at the end to launch the output.


Use at own risk! Valid dumps may be invalid - Invalid dumps may be valid.
There are almost infinite variations of each dump! Have fun and good luck!
