Pokemon Crystal Save File invalid on PKHEX

[Kiru]

Hey Guys I need some help on my crystal save file. I've been playing Pokemon crystal on my 3ds using Retroarch from the NSUI injector. I used an IPS patch that made it so that every Pokemon is catchable, idk if it messes with the save file but I don't think it should since I did the same thing for yellow and it worked fine in pkhex: https://www.romhacking.net/hacks/6088/

I wanted to transfer some Pokemon from yellow to crystal, but loading the crystal .srm pkhex is giving: 

The file rom.srm did not load into a save file.

The file is not a valid save file.

I've tried looking into the data structure of crystal using the hex editor and  the bulbapedia structure as reference, but with my little knowledge of hex code I cant figure it out.
The save works fine in game, so I don't know what could be making it invalid

Any help would be appreciated!
