Installing 4SwordsHax on DSi?

Hi there,
In preparation for the release of RocketLauncher and hiyaCFW, I'm interested in setting up a different entrypoint on my DSi. I already got Sudokuhax and a fully downgraded system settings+whitelist, but Sudokuhax taking longer to launch the exploit is a bit inconvenient. How would I go about installing 4SwordsHax instead, for that ~1 sec boot time?

Thanks in advance
