Hacking Possible to use multiple same-game roms on one Gateway?

[DDTarZan]

Hi, is it possible to have multiple ROMs of the same game on a Gateway without it only seeing one? For instance, if I took a Pokemon X scene dump, copied it twice, and changed the headers of the copies to two different headers, would I be able to choose any of the three with my Gateway? Or would it just give me an error? And will this work with .3dz ROMs too?

It's kind of a pain swapping out .3ds or .3dz ROMs everytime I wanted to play with a different save.

Pokemon will play fine on separate copies, card 1 games would conflict with each other as they would all use the same save file

Neat! All I needed to know. Thanks a billion.

It will see every ROM you put on it. But as mentioned before card1 games will have shared save files.

Its possible to convert card1 games to card2 by changing some info in the header, which would solve the save conflict problem.

yes.

Sorry, it was a statement not a question.

But it'd still read from the single save, I believe. So that wouldn't do anything, correct?

Each rom would have its own seperate save, stored inside the rom itself. Instead of it just saving to the big SD and possibly causing save/load issues

I don't think that's a set thing though. Yes, it's that way for card2 games, but I don't think you can simply change the header to 'force' it to save to the rom. I'm sure there's a LOT more code that goes into the game to enable it to save to the rom, itself. Hex editing a single value won't change that.

it does , just change the card type and the writable region offset and bingo you have a card2 game that saves to the rom like any other card 2 game

Really?! WTF? O.O

I was wrong. My apologies.

yeah i originally did it just messing about and it worked, so i shared it with the guy on maxconsole as he wasn't able to get his gateway save chip working so he could only play card2 games, i had originally asked 3dsguy to implement a automatic card 2 converter into 3dsexplorer so i dint make any tutorial or anything, but the guy who i helped with it made one anyway.....probably for the best as 3dsguy left the scene like a week later anyway, i think snailface has said he is going to make a lil app to automate the process so its not manually hex editing each game and calculating offsets

tbh the only real use i seen it having was for people who had SPI issues on the gateway card as this is a nice bypass for that, but i suppose it could be used like this as well for people who want multiple copies of the same game with separate saves
