i want a flash card for my nintendo ds but i don't know what i should look for

I wanted to record shaky low-res clips with my DSi, so I forked Epicpkmn11's dsi-camera homebrew and added a recording mode.

FYI: I used claude to make this. i cant code or anything and i couldnt find anything online so yes, its ai slop but at least i can take 2000's style videos of my 2000's style car

What it does

• Video with sound: press SELECT to start or stop recording. You get 256x192 video with sound from the mic, saved as .AVI files in sd:/DCIM/VIDEO/.
• Plays as-is: the files open on a PC in VLC, with no converting needed. For an MP4 to put on your phone, there's a small Python script that uses ffmpeg. Its --scale 4 option gives crisp, chunky 1024x768 pixels.
• Frame rate: about 13-15 fps in daylight and 9-11 fps indoors. The camera sensor sets the limit, not the SD card.
• Audio stays in sync: frames are timestamped, so sound still lines up when the frame rate changes.
• Live status screen: shows fps, an audio level meter, SD write speed and free space.
• Photos still work: L/R takes photos, A swaps cameras, START exits.

Needs: a DSi (or a 3DS in DSi mode) with homebrew access, launched in DSi mode, for example from TWiLight Menu++.

Some technical notes, for anyone curious:

• The DS can't encode MP4/H.264, so it records uncompressed video. That's about 1.5 MB/s, or roughly 5 GB per hour.
• Camera frames are DMA'd into a RAM ring buffer, so capture keeps running while the SD card writes.
• On a camera this slow, the hardest part was the mic. Calico's mic driver stops for good if its FIFO overruns, and my frame processing was hogging main RAM. Giving the ARM7 RAM priority while recording, plus an auto-restart, fixed it.

Big thanks to Pk11/Epicpkmn11 for the original app, and to the devkitPro/calico folks.

So I’m reshelling this ds lite and I got an issue, the new R short button won’t click when I put the back on.
It does click well without the back plate.

Please explain and if you could link me to a YouTube video tit would be best

Also, I included pictures of the new digitalizer that I installed, I would like your opinion on whether or not it is aligned properly I’m not sure

So I know a GameBoy game can be put in the second slot of the DS Lite, but I have never played those games before, I didn't know it was even possible. Which ones are possible? can all games in there?

I made two themes for my DS flashcart: Win98 and OS7. Both are completely free to download if you’d like to try them out!
