Hacking NDSTokyoTrim - batch trimmer with wifi detection

[BrianTokyo]

I doubt I even have to link you one. Within nds-bootstrap, the one major game with this issue was Mario Party DS, as its multiplayer mode is solely cloneboot.

Interestingly enough, some testing on my own end seems to show that it works. (It also detected Mario Party DS as a Wi-Fi game, but it isn't... perhaps that's why it works?)

Well, the rom does have a Wi-fi section though, 136 bytes after the game data, my app detects and keeps that:

1694 Mario Party DS (US)
Rom Size: 23.287.968

Hi, does NDSTokyoTrim retain the 0x88 bytes at the end of the trim data for NTR cartridges? This is specifically required for usage of cloneboot-based Download Play playback on real hardware, as those 0x88 bytes are the RSA keys.

TWL cartridges do not have this issue as the 0x88 bytes are within the "data size" header of the ROM image, but NTR carts don't retain this.

In this case as the per rom data in the file, yes, it does keep those 136 bytes. The app checks for this block on its own, it doesn't follow some rom database to determine whether or not to check for it.

I see. That's good to know (GodMode9 and GodMode9i did not do this prior to this discovery.)

Thanks! Still the best PC app for this purpose.

I definitely wasn't expecting this to be updated. Thank you so much for making such a useful program! I wanted to ask though, is the difference between stock and trimmed 3ds games big?

It honestly depends on the game. I'm sure you know that when a cartridge dumper dumps, it dumps the entire chip bit by bit, so there is the zerofilled data.

Some cartridges can have 512MB chips, but the game data could be only 260MB, or 400MB. Because each game is different you'll never really know how much storage you're saving.

I say trim them anyway. If you don't really care about proper archival and just want to play games, that's free space, however big or small.

Hi. I just want to say that I'm glad you're still alive!

What exactly is "WARNING: Card1/2 rom detected"? I downloaded Animal Crossing New Leaf game+update, decrypted, extracted+merged, rebuilded and trimmed. Up to title screen it looks to be running just fine.

EDIT: read more about it, I think card2 doesn't matter if you're gonna run it on an emulator.

You're the best! Excellent tool.
