It was in both the DS Index and hiyaCFW sections and this one was slightly incorrect (the working about starts at 4, 8, etc not 5, 9, etc)

nds-bootstrap has TWL Clock Speed as an option, but it will not try to adjust the ROM to work with the higher clock speed. That's on the application itself, and applications not working with a higher clock speed is NOT a bug on the nds-bootstrap end.
### Nintendo DSi system menu
The Nintendo DSi system menu uses a signed 32-bit integer to determine the amount of free space on the device. Using a device source that goes above the 32-bit integer limit, this counter is overflowed into a negative number, which crashes into an "An error has occurred" black screen.
The ranges that make it overflow is determined by pairs of two. For example, 1-2 GB of free space is allowed while 3-4 isn't. 5-6 GB of free space is allowed while 7-8 isn't.
This crash will never occur if the system menu is launched from an actual NAND chip (since it maxes out at 128 MB), but a redirection system (such as hiyaCFW) would cause this to trigger. Fortunately, this bug can easily by fixed by placing dummy files to set the counter at a positive number. hiyaCFW will automatically do this for you in the latest version.
### Nintendo DSi Menu
In version 1.4.0, RSA signatures in the DS cart whitelist aren't verified. There is an exploit regarding a vulnerability in the Nintendo DSi flashcard whitelist that allows you to take access over the ARM9 processor, 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.
There is also a known glitch in the way the Nintendo DSi Menu calculates free space when using hiyaCFW, for more information see the [hiyaCFW troubleshooting page](https://wiki.ds-homebrew.com/hiyacfw/troubleshooting#the-free-space-bug).
### Nintendo DSi Slot-1 access & blockout
Slot-1 access is blocked when launching applications from the system menu, except if said applications is either the Slot-1 launcher itself or System Settings. In order to launch normally unlaunchable slot-1 cartridges, you'll need to either make a System Settings exploit or install Unlaunch. Without either of those, you cannot launch unlaunchable flashcards and you cannot dump ROMs to your SD card.
