I have a version 9 PS2 with MI chip in it, and a 160 GB HDD in it. I have HD Loader .7c version running just fine on it, runs games no problem. I also have the MDMA0 patched HD Loader on it. The MDMA0 HD Loader used to work just fine, but now with nothing else changed, it just won't load anymore, and just hangs at the initial loading screen (I don't get any error message). I have another version 9 identical PS2, MI chip, and HDD, that runs the same MDMA0 patched HD Loader perfectly.
I'm not new to this HD Loader stuff, I've been using it for quite some time, but I have no clue why it's not working any longer on the one PS2 (MDMA0 version).
Thanks for any help.
