Final Fantasy Hacktics

I'm having the same issue that you are.
- Starting with the v1.0 install, I'm generating a save file.
- Modifying the save with Lioneditor, and then replacing it.
- Game doesn't recognize the save.

Tried literally what he had as well:
- Start the 1.0 game
- Minimize it
- Delete the save, replace it with the modded 1.0 save
- Maximize it
- Fail.

You're far from being an idiot, I'm pretty sure we're either missing something, or the steps he documented were incomplete.

Awesome,  I'll take a stab at it on my end, maybe something is being lost in translation?

I was also just looking for this info, and it looks like someone went down this path back in May: http://ffhacktics.com/smf/index.php?topic=8788.20

The steps they (Samb) took were:
1) First you need a jail broken iPhone. This allows you to install the older version of the game (v.1.0.0) to your phone.
2) Then use iExplorer to copy the save file to your PC, change it name to lioneditor.bin and edit it with lion editor.  Change it's name back to FFTSAVE.bin and copy it back to your iPhone (using iExploer again)
3) open the game and minimize it.
4) delete the save file
5) maximize the game and save again.
6) update the game

The biggest issue I'm finding is that it requires v1.0.0 to kick it off.  I'm definitely missing that, but it looks like you have it available, so this might be a good starting point for you.
