There is also a known glitch in the way the Nintendo DSi Menu calculates free space that can can cause an error when using the menu not from the original NAND, for more information see hiyaCFW FAQ & Troubleshooting. It requires version 1.4.0 (it was patched in future versions and didn’t exist in prior versions) and a flashcard with a modified ROM. This is a vulnerability that can be exploited, and it allows you to take access over the ARM9 processor. In version 1.4.0, RSA signatures in the DS Game Card whitelist aren’t verified. That’s on the application itself, and applications not working with a higher clock speed is NOT a bug on the nds-bootstrap end. Nds-bootstrap has TWL Clock Speed as an option, but it will not try to adjust the ROM to work properly with the higher clock speed. Most games, however, outperform the original with a higher clock speed. Some applications tied themselves to that clock speed and as a result, they will not work well with a higher clock speed. Most games of the Nintendo DS library were made before the Nintendo DSi came out, and as such the only processor available to them was 67 MHz.

The Nintendo DS shipped with a 67 MHz processor in 2004, and the Nintendo DSi shipped with a 133 MHz processor five years later. Here are the best of guides for you to follow, with step-by-step instructions: Installing Custom Firmware is quite easy, and in most cases, all you need is a (micro)SD card. The main benefit of modding your DSi and 3DS families of systems is that you can unlock more possibilities with your consoles.
