I have been building/compiling my Nook Color's ROM from the CM repo. Besides the geek satisfaction, I build for removing some extras and customize for performance. This thread is for sharing what I build for myself with the community. Here is MiRaGe.
Please thank/donate to CM project, especially the lead Nook Color developers, dalingrin, fattire, and keyodi.
Thanks to Nick N, unibroker, Tool Belt, k8108, christoophat, deboyz1014 for their generous donations.
Special thanks to nissanskylinebam for the banner.

There seems to be about 20% increase in the free RAM (available to the apps and cache) after first boot on my nook.

I will not go through all those but you can check them [URL="https://github.com/CyanogenMod/android_frameworks_base/commits/gingerbread"]here[/URL].

- Just follow Eyeballer's guide.
- If you are installing MiRaGe for the first time or upgrading after a long time, complete wipe is recommended.
- When upgrading from a recent MiRaGe build, do wipe cache/dalvik-cache only.
- If you do a clean wipe, you will need to flash gapps again. You can find it here or here.
1) Regarding the status/notification bar force close issues, I recommend unchecking the "disable full screen" option in the Tablet Tweaks to avoid the status bar crashes. This also improves the app behavior especially movies and games that need full screen. To bring the soft buttons back in the full screen mode, I recommend Button Savior (available in the Market). If you had tried this app before, Button Savior developer greatly improved the app lately. When I enable autohide feature in Button Savior, it does not occupy any space on the screen. I just use the short swipe option at the right edge of the screen and bring the soft buttons when needed. Since I keep the soft buttons on the status bar, Button Savior is only used when an app goes to full screen mode. You can even remove the soft buttons from the status bar completely if you prefer an uncluttered status bar.
2) If WiFi is not starting automatically on reboot, please see the fix in this post.
