Excuse my ignorance, I havn't had a chance to setup a game with PreEnv yet, but from what I can understand, if you are only trying to remove the noexec on the MyDocs partition so that you can execute a binary, why wouldn't a python script like so work?
EDIT:
Well, I decided to bite the bullet and give it a try. I, obviously forgot to set the permissions properly, but except for that the only problem I seemed to see was that it was taking the service name from /proc/self/exe, and that should be easy to fix in PreEnv. (I tried fixing it with my own LD_PRELOAD but it was causing unrelated issues.)
Am I missing something?
(Save it as runme.py and then in a terminal use:
$ python runme.py brainchallange)
EDIT:
OK Got it working! I am running Brain Challenge from MyDocs without any remounting. There are still quite a few bugs to iron out (I still can't get the service name correct) but it seems to be possible to work.
I updated the script, I wont post the preloaded dll for now because I messed up there a bit but basically it just returns the proper string for any readlink on "/proc/*/exe". It's late here so I am going to sleep. If anyone else has a try, good luck!

Code:
import sys import os import shutil import stat BIN_NAME = '/home/user/_preeenv_bin' elf = sys.argv[1] shutil.copy2(elf, BIN_NAME) os.chmod(BIN_NAME, stat.S_IRUSR|stat.S_IWUSR|stat.S_IXUSR|stat.S_IRGRP|stat.S_IROTH) os.environ['LD_PRELOAD']=os.environ['LD_PRELOAD'] + ' /home/user/libprepre.so.1' os.execve(BIN_NAME, ['./'+elf], os.environ)

Need help here,
I've done all the steps mentioned here :
http://www.funamess.com/tw/how-to-in...ithout-symlink
For Assassins' creed
But i can't run the game,
when i run it via x-term i got permission denied,
so i tried chmod 777, chmod +rwx on /home/user/MyDocs.../Assassins
But i get "Assassins is not executable"
help please?
It was working before using this trick so i think it has something to do with the Assassins' file on MyDocs...

I don't think you've made MyDocs executable mate, do other games run from there?
If you haven't tried other games easiest way to check is to go back into
/usr/sbin/mmc-mount
and make sure 'no-exec' has been taken out and the fmask value has been changed from 0133 to 000, if they show up as they were when you go back in then you've not saved the changes properly on exit... which is easily done.
Alternatively just install Maemodder, and press 'Make MyDocs Executable' which will guarantee it's done right

I'm pretty sure i already saved both files after editing because i double checked them.
But after doing your method, my file manager doesn't detect the internal memory and only reads mmc as "format unsupported"
So i used the trick salazar posted on previous page.
http://talk.maemo.org/showpost.php?p...8&postcount=98
that one,
after that i reboot and file manager went back to normal.
But i can't run the Assassin game, so i check the /usr/sbin/mmc-mount
And apparently it went back to default code, so i changed it again, reboot.
But it still doesn't work.. And the file manager problem show up again... Maybe it's conflicting with that problem?
Also when i tried maemodder, it says "operation aborted... already modified"
