Hacking G6 Flash: How do I copy a save game to a DS card?

[kalibar]

I own a G6 Flash and I've been playing a lot of Tetris DS on it, so I decided to buy a retail copy of the game to express my gratitude to Nintendo for making a completely bitchin' online version of Tetris (I've got my gripes with the game, but that's neither here nor there). Anyway, I'd like to copy my savedata over from my G6 to the legal DS card so I can play it off the legal one from now on. But, I'm having a terrible time doing this. I'm using loader/software v4.0, and it worked just fine for copying Mario Kart DS data to and from my legal game card from the G6. But when I try it for Tetris, I just get the "Backup saver OK" message, and then try booting from the legal game card to find absolutely no data. Don't lie to me, G6!

Anyway, does anyone know what I need to do in order to resolve this? I tried out ETool and Rein, but I'm clearly using them fucking wrong because I couldn't get any results from either of them with my G6. I have an M3 SD Slim at my disposal as well if this simply isn't possible on a G6, but I'd like to learn how to do it on my flashcart.

Thanks for your help -- you guys are the best!

Are you trying to write the rom save file to the same region game of the cart?

Cause it worked fine when I used the G6's own save file transfer from the Tetris (E) to the one I bought.

Yes, the regions match -- they're both USA.

What version of the G6 software/loader were you using when you did this?
