Your steps look correct but you do not get the results that I get. I just verified the operation again using two binary files. One file contained all $55 and the other file contained all $AA.
My files look like this:
55 file:
55 55 55 55 55 55 55 55 ....
AA file:
AA AA AA AA AA AA AA ....
Here is what I did and the result I get:
1) Set Binary Input/Output Split to 2 Files
2) Open Binary... and select the $AA file. I see the $AA pattern loaded into every other byte.
3) Set Binary File(s) "First Address:" to $000001
4) Open Binary... and select the $55 file. The memory now looks like this:
Code:
00000000: AA 55 AA 55 AA 55 AA 55 .....
Are your files already padded with extra bytes?
Make sure you are using EASyBIN v2.0.0
