Seeking complete list of save file types

I am currently working on the Online/Offline NDS Save File Converter version 2, and I need a complete list of all formats flashcarts/emulators/backup tools use in addtion to what sizes they work with.

What I have so far:
Raw Formats:
Acekard RPG (*.sav)
EZ Flash V (*.sav)
R4 Formats (Raw format with a fixed size):
R4 (512KB) extension being *.sav
CycloDS (512KB) extension being *.sav
EDGE (512KB) extension being *.sav
iEDGE (512KB) extension being *.sav
M3 Simply (512KB) extension being *.sav
TTDS (512KB) extension being *.sav
TTDSi (512KB) extension being *.sav
Supercard CF (512KB) extension being *.sav
Supercard SD (512KB) extension being *.sav
Ninja DS (512KB) extension being *.sav
M3 DS Real (512KB) extension being *.0
G6 DS Real (512KB) extension being *.0
M3i Zero (512KB, or 1MB) extension being *.sav

Other Formats:

I didn't check this against your list but I imagine it's fairly comprehensive: http://www.shunyweb.info/convert.php

Shuny's converter is how I got most of what I have.

DSTwo saves in the raw format forced 512KB using the extension .sav

I'm pretty sure games that need a bigger save file will use bigger than 512KB when needed.
CycloDS and AKAIO does this, at least.
AKAIO doesn't force the save file to be 512KB if not needed (256KB for example)
