-Nitro Engine POC 3D Test by Ti-Ra-Nog
--------------------------------------
-
-If you want to enable the FAT mesh and/or texture reading, first uncomment the
-line: "#define FAT_MESH_TEXT" and then compile it.
-
-After you have the binary file with the FAT texture/mesh reading enabled, copy
-this files to the root of your card or put them in the same folder where the nds
-is for test it on an emulator (with fat support).
-
-In orther to use the screenshot or "video" recording function you need to
-enable the FAT access to your card, if you have a new card reader for nds you
-may no need to patch it, but if you have an older one may you need to patch the
-binary file with DLDI patch for you card reader.
-
-In the binary folder there are three files, one no patched binary and two
-patched for R4 and Super card SD.
-
-For making screenshots you need to create the "/screen" folder in the root
-directory of your card and then the screens should be there.
-
-The "video" recording function make one screenshot per VBL and save it in to the
-video flother that you need to create in the root of the memory (i whasn't able
-to create the directory if it doesn't exist). When you push the "R" button the
-ds will make one screnshot for every vbl and you'll see the screen blinking and
-making some strange with the scenes, don't worry, the screenshots will be ok.
-The video will be recorded to  "/video/vid".
-
-When you have finished the the "video" recording you'll need to make a animated
-gif or avi video with some software.
-
-So, that's all, I think that you'll love this Engine :D
