+# ntrboot_flasher
+_A tool to flash that bootrom-hax goodness to your flashcart._
+
+## Supported Cards
+ - Acekard 2i HW-44
+ - Acekard 2i HW-81
+ - R4i Gold 3DS RTS
+
+Note that in some rare circumstances, it may be possible for the flashing
+process to **brick** a counterfeit flashcart and render it permanently
+unusable. This is unlikely, but nevertheless only original flashcarts on the
+list are supported. There is not a good way to test for this, unfortunately,
+and its more likely to receive counterfeit R4s than AK2i's, though most have a 
+high chance of working. There's just too much variance in these devices to 
+gurantee any chance of certainty. As such, use at your own risk.
+
+## Installation/Usage
+Instructions are documented at 3ds.guide and are heavily recommended.
+
+## Planned support/Community involvement
+Initially we planned to have more cards supported on release, but have not been 
+able to implement due to lack of time/energy. If you have a cart you would like
+supported and have the knowhow for debugging/reverse engineering a flashcart,
+please come find one of the devs in #Cakey on freenode or submit a feature 
+request. Ideally, this toolset is extensible towards any updatable nintendo ds/
+dsi flashcart. See [flashcart_core](https://github.com/kitling/flashcart_core) 
+for more flashcart details. 
+
+## Credits
+@Normmatt for initial implementation, bug squashing, expertiese... etc.  
+@SciresM for sighax/boot9strap and flashcart RE.
+@hedgeberg for testing and flashcart RE.
+stuckpixel for testing.  
+Myria for testing.  
+
+Huge props to @d3m3vilurr for figuring this out on their own!
