Hello everyone, This is my first post on GBAtemp, so if there is anything I could improve about my thread, please let me know. I'm having an issue with my Old 3DS where Homebrew now takes over a minute to load, they used to load in about 3–5 seconds. In addition, System Settings and all of my DS Roms/Twilight Menu++ no longer load at all (unless they somehow take more than 20 minutes). I might be wrong but, I don't think this is an SD card issue. I tested both my new 128 GB SD card and my old 8 GB SD card, and the problem is exactly the same on both. System Settings also fails to load even when I remove the SD card completely. I'll try to provide as much information as possible, even if some of it ends up not being relevant. So My new SanDisk 128 GB SD card arrived, so I formatted it from exFAT to FAT32 using a formatting tool. After that, I made a backup of my old SD card on my computer and copied all of the files to the new SD card. When I inserted the new SD card into my 3DS, I immediately noticed that Homebrew took much longer to load, and System Settings, TWiLight Menu++, and my DS ROMs would no longer start. At first I assumed I had made a mistake while Formattimg the new SD card. However, when I switched back to my original SD card, the exact same problem remained. I also tested booting without an SD card, and System Settings still would not load. I found another thread on GBAtemp describing a very similar issue. Following the advice there, I previously used the NVRAM/CRC16 repair, which completely fixed the problem For the Thread Creator. However, when i tried the same,Homebrew became so slow that,the NVRAM tool can not finish loading, or maybe its something else but thats what I assume. At this point I'm not sure whether the long loading times and the System Settings issue are related, but I'm out of ideas. Since its been very long with modding my 3ds Thank you very much to anyone who takes the time to read this. I'm currently on my flight home, so I may not be able to reply immediately, but I'll respond as soon as I can. Any help or suggestions would be greatly appreciated! Best Wishes!

Epic0522 · 2026-07-31T12:50:46+00:00

Hey everyone! I’ve been working on my own version of the Super Mario 64 3DS port for quite a while. What would Super Mario 64 look like if it actually treated the 3DS as a 3DS? This is Super Mario 64 3DS Port Ultimate. （The DS Bomb-omb battlefield minimap has been replaced in the newer version） Compared to the original SM64 porting project, there are more new features. Please use New 3DS to get the best performance. The complete source code, build instructions and development screenshots are available on GitHub: https://github.com/Epic0522/Super-Mario-64-3ds-port---Ultimate Credits This project builds on the work of the Super Mario 64 decompilation and porting communities, including: • n64decomp/sm64 • sm64-port/sm64-port • sm64-port/sm64_3ds • mkst/sm64-port and its earlier 3DS minimap work More detailed information and credits can be found in the GitHub repository. Thanks for checking it out!

I have a question about the structrue of JKSV Savegames. There is a 3dsbrew wiki page about
savegames (https://www.3dbrew.org/wiki/Savegames). Does this article applies to the savesgames dumped with JKSV and Savedatafiler?

Furthermore, is it possible to know from which game a savefile is dumped from? Maybe the gamecard ID or something to identify the game.
If yes, would I be able to this data by using a hex editor or would I need to parse the data even further?

AFAIK that 3dbrew article is about the low-level structure of the raw data. JKSM extracts the logical data contained within that structure.

Damn, that's what I thought. So if I understand currently JKSV throws everything away that hasn't to do if the actual save game data.
That means I can't get any infos on what game the save belongs to or if the savefile is even a 3ds savefile.
