Save dilemma in advance wars 1 (VBA)

[nmego]

So I had my VBA savetype as EEPROM Flash 128K, and started Advance Wars 1, every time I tried to save in-game, and reload it, it just creates a new game.

So I settled for save-states and I went pretty far in the game, beating the campaign.

And after I've done all that, after some screwing around I found out that it does save with Flash: Flash 64K.

I started a new game, saved in a VS Map, and after restarting the game, I've noticed that everything works fine..

So I tried to load my savestate and save the game from there.
After I reloaded the savestate, It brought me back to new game again.

I think the savestate is stuck as "EEPROM Flash 128K". Is there's a way to convert between EEPROM Flash 128k and Flash Flash: 64K?

If not, how can I bypass this problem? I don't want to start a new game.
