Ive read through the pinned reference section of the mxm action scripting but i cannot find out if mxm allows you to edit files 1 byte at a time (id use the search but lately it never seems to be disabled) The reason for asking is because i have written a program in C to edit xbox bios files so you can change the colour of the startup and the camera animation etc, id love to have a go at writing a script to do this in mxm but cannot findout if this is beyond the scope of the scripting langauge.

Regards, Guy

I think this capability is only in the WIP (beta) versions at the moment, as I believe they have 'proper' file i/o functions.

Yes you can in the WIP version.

Look at the Buffers section. While you wont be able to test it yourself you could still try to write a script based on the WIP specs.

Hmm, maybe you could or someone else could post an example of how to begin editing a file, using buffers, 1 byte at a time ?

Well I'm not the ideal person to ask... but

This is how I would think it could be done. Mind you I tried this with the default.xbe and changed the Matrix Init screen from green to blue.

First you need to know the Buffersize you want to work with.

This is how i did it

CODE
Set COLOR RED

SetFunc SizeOfBuffer FileSize $ActualPath$\default.xbe

OpenRead InFile $ActualPath$\default.xbe
OpenWrite OutFile $ActualPath$\default.xbe.patched

CreateBuffer PATCH %SizeOfBuffer%
ReadToBuffer InFile PATCH

Goto %COLOR%

:BLUE
SetBufferByte PATCH 1977788 0x32
SetBufferByte PATCH 1977789 0x58
Goto Done

:RED
SetBufferByte PATCH 1977788 0x31
SetBufferByte PATCH 1977789 0x33

:Done

WriteFromBuffer OutFile PATCH

CloseHandle PATCH
CloseFile InFile
CloseFile OutFile

You could also read in only the part that you want to edit (instead of loading the whole file into memory), and write that part out.
