This is great! Mr SCUMM promised he'd make scumm compatible with supercard if he could have the source... I'll send him these links now

Will this open the way for sc trojan writers? – wouldn’t put it past the m3 a$$holes

This patch is aread open ( Ds.Briker )..  you just have to pay attention to where are you download the homebrew!

I hope Chrism add's this to his library, he already has m3 and gbamp in his library, if developers could access all 3 of these readers with ease that'd make developers alot more interested in making direct cf access applications. I heard that pepsiman from Dslinux is already adding the api to dslinux.

Don't forget the most important thing... NDS Game Backup Someone should make such a program, compat' with the SC SD/CF.

I agree! Then I could backup my original carts to go with my original saves since it seems like my version of Bokujou Monogatari is different from the already dumped version making my save incompatible.

This code must run in GBA(or NDS)'s RAM.

Plese run program at address :0x2000000---0x4000000 (GBA or NDS RAM)

[equalizr]

wow..that was fast.

I was the only person asking when and if the source code will be released just a few weeks ago and here it is.

also posted the same thing on supercard.cn

way to go romman  

[cory1492]

Really? I asked for a direct method of accessing the MM card along with an NDS menu/kernel or at least a hack like GBAMP back when I started working on DSBook a couple months ago

Although you are right, it was bloody fast (all my requests towarads non-illegal things like this have been fulfilled in 2 months    not to mention the bonus updated NDS patcher)

mysql, can you confirm it is infact workable/working code for both GBA and NDS? Wouldnt the devkitARM dsbuild loader already take care of loading the code into the correct memory area? If not how would the above sample need to be modified to put it into the proper memory locations...?

[sWampy]

Although you are right, it was bloody fast (all my requests towarads non-illegal things like this have been fulfilled in 2 months    not to mention the bonus updated NDS patcher)

?? Did I miss a new updated NDS patcher?

[MisterJP]

larryli, did you managed to make your code work ?

I have the same problem (whith a SD version); it seems that the initialization function (InitSCMode) does not work.
It is supposed to send two times 0x0A55A and two times 0x3 to 0x09FFFFFE, then it should unlock the SD access mechanism, but it doesn't.
We are also supposed to read the status of the Supercard SD (ready, inserted...) from 0x09800000, but i always get 0...

If mysql is around here, maybe he could help...

The latest update to the SuperCard software contains updated NDS patcher... as far as I know ndspatch 0.1 and GST universal patcher 3.1 are the only currently available stand-alone NDS patchers though.
