R4 SDHC DS Happybox

Note

These instructions should apply to any r4isdhc.com cart using the 1.19B kernel, not just the one shown in the image.

Warning

This cart is an R4SDHC clone, and like the R4SDHC, SD I/O implementation is wonky since its SDHC I/O code is closely based off of the original R4's I/O, meant for SD class cards rather than SDHC ones. This causes the cart to be unstable with SD cards bigger than 4GB. (It will work with larger cards, but they may cause issues. Consider yourself warned.)

Setup Guide:

1. Format the SD card you are using by following this guide.

2. Download the r4isdhc.com 1.19B YSMenu 7.06 autoboot package.

3. Next, extract the contents of the downloaded kernel zip to your SD card.

4. Place any .nds game ROMs you'd like to play into the Games folder.

5. Insert the SD back into the cart, plug the cart into the DS, and see if it boots into the menu.
