Hm... well, with Card Fighers Clash, the NGF backup from the official cart was 65KB in size. The size of a save (not save state) using NeoPop varied between 5KB and 7KB.
Loading the 65KB NGF save file using NeoPop worked fine. However, when NeoPop saved data, it replaced the previous NGF file with the much smaller version. I was hoping it would just edit the larger save file, but that seems like a no-go.
I was able to transfer the save from the NeoPop by replacing the contents in the 65KB file with the NeoPop save in the location that matched up. Transferring worked, but I did receive an error about an incorrect save header using the GUI tool. Still, the save worked fine.
Looking back, I really should have documented my struggle a little more with screenshots and the like. I guess I could always reproduce the steps I took. The old save and entire cartridge were backed up when I started this, and I've got duplicates of this game; so, I'm not that worried.
