Well, I'm a member here for a long time (since 2004!). That nick originally comes from Duke Nukem.

now it's failing to read the NCSD header. I just built the "gcdumper" branch and tried it out.

Code:

Detetcted cartridge id 9000FAC2... Error reading cart NCSD header Dump & Decrypt Cart (slim): failed! Press B to return, START to reboot. Detetcted cartridge id 9000FAC2... Error reading cart NCSD header Dump & Decrypt Cart (slim): failed! Press B to return, START to reboot. Detetcted cartridge id 9000F8C2... Error reading cart NCSD header Dump Cart (full): failed! Press B to return, START to reboot.

oh yeah, it doesn't seem to be putting them in "D9Game" even though it tries to. it's always "Decrypt9".

Yeah, I messed up again, but this time it will work, guaranteed:

... or compile from master. Everyone can test!

Possible to dump the header, and just the header, without dump the full cardrige then use gateway rom patcher for extract it?

I wonder, what would be the good in this? Gateway ROM patch only fixes headers, afaik.

game card dumping & decrypting works fine now, but it still fails to create it in /D9Game, even if the folder exists.

Code:

Alright, I'll look into that issue. Into on-the-decryption, too. Thanks for testing!

Do I see DS cart dumping code there?

There is, but it does not work. For now, it will only dump 3DS carts.

Oh well

I still have hope for the future though.

Yupz,
Can confirm that error, but dumping works

Thanks for that!
Finally i can get rid of uncart!

d0k3 · Jun 22, 2016

Alright, new testing version for everyone! I'm especially interested in dumping & decrypting newer carts (post 7x). This one adds on-the-fly decryption, meaning that dump plus decrypt won't take much longer than just dump anymore. Also, that /D9Game error was fixed, thanks for pointing this one out.

Not yet, coming up. We need to get that cart dumper thingy running reliable first.

OK just wondering is all

Hey, sorry if there is an easy fix for this or I'm just dumb, but how do I open it? I have Luma3DS and I have no idea how to open Decypt9. I used to be able to open it with holding a button on bootup but now it just stopped.

I think @Shadowhand fixed it already.

Read the Luma3DS readme - maybe you have to change the name or something like that.

Thanks a lot for testing this! I've also seen you've got a new Python CIA converter, so I'll recommend this with my next release notes (Riku's converter can't handle decrypted roms).

Anyways. guess what? I need another round of testing. The last revision of the cart dumper/decryptor would fail with certain carts (MH4, for example). You can compile fresh from onthefly branch or just get it from here: https://up1.ca/#1rnJiJQCxGR-kb1CNiGqhg

If you can, also verify the dumped / decrypted ROM on PC somehow (f.e. by fully extracting it with ctrtool or comparing with a known good one). This should be the last major revision before release, too.

No-Intro have dat files with the encrypted full dump checksums available. Would those be useful combined with the stand alone de/encryption functions to verify dumps?

why would it fail with these carts? large size (MH4U is 4GB I think)?

Not for decrypted ones, as No-Intro only has encrypted checksums.

ihaveamac said:

Large size ExeFS actually. MH4U is a problem itself because of 4GB (FAT32 can't take files >= 4GB), but I workaround that by silently removing the last sector in that case, and it is only an issue if you dump full (which you shouldn't).

Does reencrypting them not give the same checksum?

Just as well there's no 8GB carts yet

Not for sure. Cause there are different kinds of crypto - pre 7x, post 7x, Secure3 (N3DS carts only), Secure4 (N3DS eShop only), seed, .... You'd need to reencrypt with the exact same settings.

--------------------- MERGED ---------------------------

Btw, before I forget about it - take a look at the new progress indicator in the decrypted cart dumper - it now works properly from 0%...100%.
