Hi

Gives any tools for it?

Code:

;--------------------------------------------------------------------
format            PE      gui 4.0
include     'win32a.inc'
;--------------------------------------------------------------------
xm_lib        file    'ufmod.dmp'         ; must be at 0x00401000 !!!
xm_play     =      xm_lib + 9158h
xm_stop     =         xm_lib + 0D8h
xm_handle   =          xm_lib + 1Ch
;--------------------------------------------------------------------
xm_file     file    'glass.xm'
xm_size     =      $-xm_file
;--------------------------------------------------------------------
caption     db            '.:FASM:.',0
message     db        'uFMOD ruleZ!',0
;--------------------------------------------------------------------
entry            $
           push    xm_size xm_file [GetProcAddress][GetModuleHandle]
           call    xm_play
     invoke  MessageBox,0,message,caption,MB_ICONQUESTION
        push    dword [xm_handle]
           call    xm_stop
     invoke  ExitProcess,0
;--------------------------------------------------------------------
data          import
library     kernel32,'kernel32.dll',user32,'user32.dll'

You mean like a process crash dump? For that you can use the MiniDumpWriteDump API.

But from looking at the source context, it sounds like I may have mistaken the context of your question.

What kind of .dmp file? What for?

Are you trying to create your own file ?. Use Win32 API CreateFile, WriteFile, CloseHandle...

xm_lib file 'ufmod.dmp' ; must be at 0x00401000 !!!
^^^That seems like you are trying to extract the file from some place.

If you know the structure of the file then you just move that offset into a register, EBX (I also rec. you push EBX first)... and then access the file contents by their address for ex.

Code:


;assuming you have the file address in EAX

MOV EBX,EAX

MOV EAX,[EBX+nBytes_Of_Item_here]

MOV dword[Some_Variable],EAX

JMP .WriteSomeVariableToFileAndComeBack

Is that it ?

Just download ufmod package and look inside, there are some fasm examples inside to get you started. The source you posted is pretty outdated IIRC.
