Are you trying to do something specific with EdiZon? If you already have EdiZon installed on your switch you can go to cheatslips and get the cheats, extract it to the folder, then run EdiZon when you start the game to enable if it isn't already set to auto enable already. They have a pretty comprehensive generic cheats for FE3H on that site.
Something more specific like modifying stats, growth, etc or similar to what I'm doing, you would want to follow
TheMageBlood guide that he posted a link for.
If you need a more visual reference look up [Switch] How To Setup & Use Cheats With EdiZon by DarkFlare on YouTube

No worries, I had thought you meant to look up those on this forum or on google but still much appreciated, I had a look at this guide and its very comprehensive indeed. I have actually just finished dumping the files and will proceed on playing around with the Fixer_Person_Data.bin file like you suggest, thank you again
[EDIT]
@TheMageBlood I originally had an issue using Aldebaran even though I followed the guide to put the bin file in the /romfs/patch4/nx/data/ it didn't work when I booted the game in CFW. After trial and error I figured out the issue. Current release of
[FETH 1.2.0] Aldebaran v0.1.2 is not stable; namely the subsdk2 file is causing the issue and seem to be the same case even if you downgrade to
[FETH 1.2.0] Aldebaran v0.1.1 (must've been carried over in the code). You can download
[FETH 1.2.0] Aldebaran v0.1.2 but don't use the subsdk2 file from that version, instead grab it from
v1.1.2 and it would still work. If you do happen to come across the socket crash issue that version of the code contains (it varies based on your Switch's ver.), then simply downgrade all the way to
[FETH 1.2.0] Aldebaran v0.1.0 as that is the most stable one. Overall, the guide you provide works but I'm not sure if you want to make a note of it there or wait until the [moderator] Raytwo of that GitHub realizes the issue and fix it in another release but regardless thank you
