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.

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.

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

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.
