Long ago I needed a program to interleave 2 binary files together. At the time SirMorris over at the RCM forum made one up and it did the job nicely.
Since that time, ive got into programming myself and decided to make my own program that did exactly the same thing. From then, I kept adding bits to it to make my life a little easier and focused on ease and speed of use. Its now progressed into something that I use regular when dealing with ROM’s and things.
Interleave 2 files
Swap upper and lower portions of a file
I’ve had quite a surprising number of people tell me they also found it useful which is nice.
