Hacking dsbuff

[WB3000]

This is just a small program I've whipped up recently, and currently it's at version v1 Final

The current features are...
-Trim
-DLDI
-Unpack
-Pack
-Arm7 Swapper
-Header Editor
-CrashMe Scan
-Drive

This release has been entirely rewritten using C#.NET, and features a new interface. I won't go into detail now, but you can try out the beta if you wish.

dsbuff v1 Final .ZIP file

*Requires .NET Framework 2.0!

Version 0.2 is up now, which mainly includes the addition of all the DLDI patches! If anyone would like to see any more features, please say so!

 

[WB3000]

I uploaded version 0.3 to the DS-X forums thread only, since the only new things are an options menu to filter out the DLDI patches you don't need, and a ARM7 swapper, which is only useful to DS-X owners right now.

EDIT: You can find it here now

Hmm this program looks useful ima try it out.

Does it require .net?

 

[WB3000]

Does it require .net?

Yes, like dslazy, this program requires the .NET Framework 2.0

.NET sucks

.NET sucks

Is your main harddrive called C:\? If stuff like that pops up, just hit continue, and it will move on.

safe trim?

 

[WB3000]

safe trim?

Trims identical to dslazy, if anyone has a command prompt style safe trimmer or VB.NET code for that, it would be appreciated

 

[Shuny]

.NET sucks

.NET is a great and modern framework ...

 

[FAST6191]

I will not get into the .net debate, sure it lessens DLL hell but I kind of resent having to download a 20 meg framework for a 200K app (and hoping it works with the version I have).

I can not give you any code but all that "safe" trimming is:
reads 4 bytes from 80 (hex)
If first 4 bytes can be said to be
ABCD they become DCBA
e.g. 1302 Sommelier
24C29302 becomes
0293C224
Delete all following this newly derived address (gba era and early trimmers just deleted until there were no more 00/FF's).

I'm not that technical with my coding lol, I don't know any other language besides VB.NET. I am currently using the trim.exe from dslazy, but I think I know where I can find some safe trimming style code...

And for that error regarding the options.txt, just hit continue like I said before, then run one of the commands in the program. The error is caused by the C:\dsbuff\ directory not being in place before creating the options.txt.

How about checking if the dir exists on start up?

Just call GetFileAttributesA in kernel32.dll and check for FILE_ATTRIBUTE_DIRECTORY ($10)

if it doesn't, just make it, CreateDirectoryA also from kernel32.dll

I've implimented that on my end already, though in VB it reads more like "If directory exists then do nothing else create directory" lol. But that error will not appear after your first use.

Anyway, both VB and .NET suck

Easier to use though.

 

[FAST6191]

If you want ease of use can I suggest you look at autoIT, it is pretty good for GUI making (it can spit out command line, screen positions related stuff, call DLLs, make directories/(text) files, registry stuff... and some binary stuff (not so good at reading/editing)).

Syntax is somewhere between C? and new style basic (Visual Basic and the like) and there is no need for clunky framework.

If you want something that is coded in it look at BatchDPG.

What does the ARM7 swapper do?

 

[FAST6191]

The DS has two processors, an ARM7 and an ARM9, both of which work in DS mode. Each naturally runs its own code which courtesy of the DS file system can be accessed very easily.
It was found that the ARM7 binary controls copy protection for some titles meaning cards that patch the game to run (most of them) that had not been updated could simply swap out the ARM7 binary (which courtesy of nintendo's dev tools is very similar between most DS games, something I would probably not have guessed) with another usually "older" (i.e. the Japanese release) arm7 binary and have it work.
