PKHex Rendering HG Save Unplayable - Drastic Only! - Works on Desume!

[ZacHacks]

I've been playing HG on my phone using Drastic. I had but a simple desire: to have my Graveler evolve into a Golem. But with no trading supported on Drastic I was without hope. So, I did what any simple man would do... I got a computer science degree and become an operating systems engineer... Kidding aside, I just want to have a Golem in my HG save that I play on my Pixel 7 using Drastic. 

So, I open up PKHex on my Windows 10 PC, click, clack and my Graveler is a Golem. I export the file and put it back in the "backup" directory on my phone where I got the unedited .dsv file from in the first place. I go to launch the game and nothing--Drastic just quits back to the menu. I put the old file back--works perfectly. I did all kinds of troubleshooting. I looked at the two .dsv files in a hex diff tool. The sizes of the files don't change just some "bits in the middle", presumably the Graveler bits. 

The real kicker is that I downloaded Desume on my PC and was able to open up the edited .dsv there and see my precious newly evolved Golem following me around.

So, why, ohhhhh, why is the file not working with Drastic on my phone?

In case anyone will wonder, yes, I did make sure the .dsv file had the same name when put back in the backup dir.

Two more bits of data:

1. I took the working file and opened it in PKHex and did nothing to it and exported it and tried loading it and it DID NOT WORK.

2. I sent the working file to my PC and saved it there. I did nothing to it, didn't open it or anything. I sent it back to my phone and saved it in the backup directory and it also DID NOT WORK.

Point two makes me think that permissions might be to blame, but the file manager app on my phone was showing -rw for both of them but I am going to look into that more.

I removed the additional footer of the save file and it should be playable now.

Check it and tell us how it goes.

Unfortunately, that did not work, but thank you for the suggestion. It failed in the same way as before.

Given that just saving it onto my PC and then sending it back to the phone makes it unplayable, it doesn't seem to be the file contents that are the problem but rather the metadata.
