Hacking Save conversion

[Omnigamer]

I'm trying to convert a G6 Pokemon Diamond save to a save usable by the M3, but so far nothing's working...

Using the Save Manager with the M3 software makes the file corrupt and cuts off about 40 hours from my playtime, starting me off way back and with a lot of work lost. Using the one web-based save converter (name escapes me) turns it into a 256 kb .dat file, which is an incorrect filesize (it uses 512 kb), and is unusable by the M3 Cart. How should I be converting the save so that it actually works?

After the web converter use Pokesav to make the save 512KB then use the Manager. I had the same problem when trying to use a different Flash Cart save.
