I have been doing experiments using the code on my Supercard DS One SDHC. I also did a .scc with the code and loaded the game using the same settings that you mention, and i got mixed results. I have 3 memory cards, 1 Adata 4gb Class 6 Micro SDHC, 1 Sandisk 8gb Class 6 Micro SDHC and 1 Kingston 2gb Micro SD. With the Adata 4gb one, it happened as you mention, it saves and i get a black screen after that, having to reset, then i get a black screen just after Bowser fight (tried around 8 times, changing settings a bit, going to Bowser without saving before, etc.).granville said:The game will boot and play for a few minutes in Supercard DS One using this cheat I compiled from Normmatt's original bypass-

But the game will freeze whenever you save (it saves fine, you just have to reset whenever you save and continue). It also freezes after the first Bowser battle. So the game is still unplayable on it.
Settings to get it to work partially if you want to try-
-Patch enabled
-Patch Speed enabled
-DMA enabled
-Save Patcher enabled
-Cheats enabled
With those you can get ingame at least and past the file selection. Modifying the save size doesn't seem to do much. And all of the options above need to be checked to get the game to work at all.
With the second one, the Sandisk 8gb, i managed to get past the Bowser fight (with a brand new savefile, didn't save before it), then saved at the next save point (a bit after all get absorbed by Bowser) and got the black screen after saving (again). I could continue from the save, but then i got a black screen after the next fight finished (killing the first goomba with Mario).
And finally with the Kingston one, i managed to get past Bowser fight (again with a brand new save and without saving before it), i skipped the next save and continued playing, killed many goombas and then saved in the next save point (the third one available), but this time i selected Save and Quit. It got me to the title screen (no black screen this time), but somehow it didn't apply the cheat (i wasn't able to select my file). I tried restarting 2 or 3 times, getting the same results (couldn't select my file, i checked that the cheat was actually active) and decided to give it up for some hours (i got a bit tired, lol).
So i don't know what to say, i kind of suspect that the problems might be related to the black screens after saving (considering something like, you can play using a brand new savefile and advance without black screens as long as you don't save, based on my results, since i skipped saving at the 1st then the 1st and 2nd saves on my 2nd and 3rd try and i could advance a bit more each time), but atm this would be only speculations, might try again with my first card with brand new saves to see if i get a different result. Or maybe it has something to do with the memory cards.
