Eventide does not compile right now. This disclaimer will be removed once it does.
Eventide 
Eventide is a CTR-mode frontend for nds-bootstrap. Forked from TWLoader, Eventide aims to be an alternative to TWiLight Menu++.
Why?
Over the years, as TWiLight Menu++ has evolved, the launcher has become more and more powerful- in my opinion, to a fault. While TWiLight Menu++ is great for flashcards (I run it on my AK2i, even) and DSi systems, I do not believe it is an optimal solution for 3DS users at this point. TWLoader was more focused, and I liked that about it.
The straw that broke the camel's back was when I was attempting to get widescreen patching working on a per-game basis reliably. While it does function in TWiLight Menu++, it has a tendency to lock itself into widescreen mode permanently until the sysmodule is manually renamed and moved back into the TWiLight Menu++ directory. Plus, the potential speed benefits of launching a rom straight from TWL_FIRM are negated, as the system has to reboot back into TWL_FIRM anyways. I tried finding alternatives to TWiLight Menu++, only to find that there aren't any, and I was tired of waiting for somebody else to make their own frontend.

Building
Install devkitPRO and devkitARM. You will also need makerom and bannertool in your PATH.
On Windows, use compile.bat, and on Unix systems, use compile.sh. This should work on any *nix that devkitPro supports, but I have only tested on Linux.
