Ah - but did you notice I stated 'stardust.SAV' (Small 's' @ the beginning) when the game is called 'Stardust.nds' (Capital 'S' @ the beginning)
Anyway, to put everything you've done all together -
> You've converted your No$GBA SAV to DSTT SAV using Shuny webpage (I'm guessing your No$GBA sav still shows 'continue' within the game)
> Copied converted SAV onto DSTT & changed name to
exactly the same as nds file (case sensitive & all that)
> Started 'Stardust', but do NOT get a '
SAV not found - Create one' type message (this implies that it recognises that there is already a SAV file created)
> Game starts - but 'Continue' does not show up
If so - I can only guess 1 of 2 things
1 - When converting using Shuny webpage, it's corrupting the saved info or making it unreadable by the game - so the game goes into 'Normal New game' mode
2 - The DSTT firmware isn't compatible for that particular game ROM, & you have to wait for an update on the firmware
The only other thing I can suggest is -
Have you tried copying the No$GBA SAV directly to the DSTT (with no convertion) ? - I betting that when you try to start the game you
willget the 'No SAV found - Create ?' message since it's a different format, but you may be lucky & the DSTT may recognise it
Other than that I'm stumped
Sorry I can't help any more
Edited:
I found a post @
http://gbatemp.net/index.php?showtopic=142120, & looking @ post 5/6 it seems that the No$GBA can create SAV in 3 different formats 'Compressed'/'Uncompressed' & 'RAW' - Shuny web doesn't state what type it will accept, but maybe your No$GBA is in a format that not acceptable & that could be why it's may be getting corrupted
There is also another post here @
http://gbatemp.net/index.php?showtopic=142230 & although it's for the R4 - it may help you
I would suggest backing up your original No$GBA SAV to pc before attempting any of this - just in case something goes wrong on the No$GBA
