This is a tool created to inject strings using low level code

• Help translate a game without discovery about he packget/encryption.
• Help use Non-ASCII Characters.
• Help with a customizable Auto-WordWrap.
• Help translating text from native window controls.
• Help translate strings with unpredictable content using masks
• Allow put your group logo in the game startup
• Can use with just a small assembly knowledge

Our strategy to inject the string is create a new section using tools like the Stud_PE or CFF Explorer to have space in the executable to append the new code, a commom method is replace a original command and jump to your code, generally a jump have 5 bytes of length, sometimes you need replace more than one command and don't forget to place original commands like CMP and TEST after the execution of your code, of course, if have one.

@StrInject:			;Declare StrInject Label
	push EDX		;Backup EDX, ECX, EBX Registers
	push ECX
	push EBX
	push EAX		;The EAX is the string pointer or a unicode character
	call GetProc		;Here the Srl.Process Pointer is catched
	call EAX
	;The next line is to the SRL.Process only
	add ESP, 0x4		;Discard the last "Push EAX" (The SRL.Process is Cdecl)
	pop EBX			;Restore EDX, ECX, EBX Registers from the "Backup"
	pop ECX
	pop EDX
	jmp RetPnt		;Continue the Execution

Keep in mind, the add ESP, 0x4 is required when you use the SRL.Process export, if you use the SRL.ProcessSTD or SRL.GetDirectProcess you can't put this line.

We have various method to catch the Srl.Process Pointer, this one is to games who have a dynamic main module alocation, is possible use the sample bellow if you have injected the export in the game executable, you can use Stud_PE or CFF Explorer to do this, You need too create a new executable section to append our new code.

In the case of this Sample the Srl.Process address in the import table is allways relative to the our new executable section.

In the code bellow the catched EIP is to the "pop EAX" and the Srl.Process in the import table is for example 0x02B9C400 and the "pop EAX" is at 0x02B9E44C, so... 0x02B9E44C - 0x02B9C400 = 0x204C, now if we subtract this value of the EIP we can get the position of the Srl.Process pointer.

If you wanna use the SRL to put Non-ASCII Characters you need call the Srl.Process and give the char of a GetGlyph function to he.

@GetProc:
	call @Nxt		;Call the label Nxt
@Nxt:				;Declare the Nxt label
	pop EAX 		;Catch the EIP :)
	sub EAX, 0x204C		;Subtract the Difference from the EIP and Import Address
	mov EAX, [EAX]		;Read the import table
	ret

After some problems with games that reload string inside a loop I created the GetDirectProcess, to import this function use the same method of the SRL.Process above, But you will change the GetProc, here a example code:

@GetProc:
	call @Nxt	    	   ;Call the label Nxt
@Nxt:			    	   ;Declare the Nxt label
	pop EAX 		       ;Catch the EIP :)
	cmp dword [EAX+0x21], 0;Verify if already have the Address
	jne @Finish
	push EAX              ;Backup NXT Address
	sub EAX, 0x2050		  ;Subtract the Difference from the EIP and Import Address
	mov EAX, [EAX]		  ;Read the import table
	call EAX              ;Calls the GetDirectProcess
	pop EBX               ;Recovery NXT Address
	mov [EBX+0x21], EAX   ;Save the Process Address
	mov EAX, EBX          ;Prepare to Finish
@Finish:
	add EAX, 0x21         ;Ajust Pointer
	mov EAX, [EAX]		  ;Read the Process Address
	ret

@Ptr:
	dd 0                ;Here is the @Nxt: + 0x21

You don't give pass nothing to this method, just call and catch the EAX, the EAX is a pointer to the Process function, using this pointer will be more fast to call the function, Keep in mind, the pointer given by the GetDirectProcess, is a STDCall function, so, you don't need pop the pointer given to the Process before
