GBAsave and DSsave difference

[madato]

What is the difference?

You see this in filenames of roms for nds homebrew. There are separate versions of any given rom for each type.
If you need to know, I have a DS Lite (v5 I believe) with a Supercard Lite with a Superkey.

Oh and what are nuke roms? Or just nuke in the filename. Hmm?

Are you talking about how some end in .ds.gba and some end in .nds? It has to do with the device launching the program. Files that end in .ds.gba have a header attached to the front so that they can be flashed to GBA flash carts, while .nds files have that header removed and launch on most other devices. However, Supercards are weird and usually require the .ds.gba versions, renamed to .nds so that they show up in the file menu. To avoid confusion, most people rename them to .sc.nds

So to make it simple:
.ds.gba - has header, used for GBA flash carts
.nds - no loader
.sc.nds - actually renamed .ds.gba file for use on Supercards
