[BUG] GBA VC save inject not working on some games like Pokemon, need help with plug-in

[TheFireHedgie]

Sorry if it ain't the place to ask, but I recently had problems with GodMode9. My Reddit account was hacked and suspended (so I can't ask there for help neither) So my problem is that every time I play a GBA VC game, I need to follow some steps to import or extract its save file. However, Pokemon games have a bigger file size (128k instead of 64k). I then found a GodMode9 plug-in for super-easy GBA VC saves handling... but author wasn't seen or heard of in 3-4 years... The plug-in is called GBAVCSM, if you wish to know.
How did it happen? OK, here are the steps I did in order so you can do the same.

• 1 - I downloaded the latest version of GodMode9 and GBAVCSM.
• 2 - I inseted my SD Card in my PC to copy the folder's contents to the "gm9" folder.
• 3 - I reinserted the SD Card back in the 3DS.
• 4 - I launched GodMode9 by booting the 3DS with the START button pushed.
• 5 - I pressed the "Home" button, then chose "Plug-ins"
• 6 - I selected "GBAVCSM" from the list, but I get a fatal error each time I try to boot it... (I used the photo I took with my camera then posted it on a thread on GBATemp under the username "NitroHedgehog", but no one knows my problem so far...)
  

Info about my system

• Console type - O3DS XL & O2DS (I have this issue on my 2 consoles.)
• No defects or custom modifications on any console
• Bootloader is boot9strap
• I chainload GodMode9 via Luma with the guide.
• Authentic 32GB SanDisk SD Cards used (NOT MicroSD)

Must I switch to fastboot3DS using https://github.com/d0k3/OpenFirmInstaller or boot GodMode9 via Rosalina to make it work?

As I said, the plug-in's author hasn't been online for at least 3 years, (according to his profile...)
