+## Features
+
+- Supposing you are a TwilightMenu++ user (or any other DSi CFW), or you use the same SD card for both the DSi and a DS flashcard,
+  FSPDS automatically detects default flipnote export paths for you so that you are not required to copy those files to a `/flipnotes` directory.
+- A screen saver turns off the bottom screen on 5 seconds of inactivity during flipnote playback. Also, this option can be manually
+  triggered by pressing the screen saver icon on the Player Tab. *
+
+\* Check the [Hardware vs Emulator compatibility](#hardware-vs-emulator-compatibility) section below.

 ## Bugs/Limitations
 
 - FSPDS doesn't detect/play flipnotes larger than 1MB (this is intentional behavior)
-- Don't place more than 1024 files in the `/flipnotes` directory, otherwise FSPDS won't be capable to see them all (also intentional behavior, probably will be changed in the future)
-- The flipnote's BGM track should be smaller than 512KB in order to be played correctly. 
+- The flipnote's BGM track should be smaller than 512KB in order to be played correctly. However, the DSi Flipnote Studio only allows
+for 1 minute of raw audio (8192Hz) to be encoded into a flipnote, which means at most 240KB of sound data. Therefore, FSPDS should not have
+problems playing original flipnotes. Spin-off flipnotes which contain huge audio data may not play correctly with this application.

+### Hardware vs emulator compatibility
 
-### Tested on DeSmuMe emulator and R4(i) flashcards
+- On the hardware, loading files from FAT system is substantialy faster.
+- For some reason, the screen saver does not work on DeSmuME emulating in R4 mode. This doesn't affect the actual user experience.
