If this only supports saves of 512 that means it can only work with diamond and pearl. The 1mb save is needed for Plat HG and SS otherwise you get errors in the game.
OKAY, kid gloves are off.
Considering I am making a "Save Editor", and all, I like to think I know at least a little bit about how the save files for pokemon work. HGSS has a 512kb raw file, just like how Diamond, Pearl, and Platinum have 512kb raw save files.
To be completely honest the save files have a great deal of 'empty' space in them.
Each save consists of two complete save 'files', each of these blocks is composed of two smaller blocks (the large and small block if you know the lingo).
One of those 'files' comes to a grand total of only 137744 bytes (~134.5 kb) in HGSS. this means only about 52% of the entire 512 kb is used.
If this was a couple bytes smaller you could fit an entire raw save into a 256 KB file. 1 mb are you insane? What do you need almost 755 kb of empty space for? Nothing. Okay.
