ROM Hack Save Game Editor help

[omarrrio]

hi, i need some help, it's for a save game editor i'm making, for an NDS game, but i don't know these things:

1- how to open the save file in decimal for a special adress
2- how to save the changes on the same .sav file (already open) without opening a dialog window (File browser)

i use: visual studio (especially Visual Basic)

thank you

I never used vb before but it should be similar to C#.
So here is the answer of you first question:

This is for opening a file to write in it!

'// First the filestream
Dim fs As FileStream = File.Create("C:\testfile.bin")
Dim utf8 As New UTF8Encoding() '// The encoding (can be change if needed)

'// now open the filestream with binarywriter
Dim bw As New BinaryWriter(fs, utf8)

Next go to a specefic position!

'// Using the seek() method to go to the position (in this case 500d)
bw.Seek(500, SeekOrigin.Current)

Parameters of Seek(): Seek(offset, origin)

offset
Type: System.Int32
A byte offset relative to origin.

origin
Type: System.IO.SeekOrigin
A field of SeekOrigin indicating the reference point from which the new position is to be obtained.


I hope this helps you, if you have questions feel free to ask.
