Hacking Problems with CoD: Black Ops & Metal Slug Anthology

[MigueelDnd]

So, I've got these two problematic games and wondered if you guys can help me out.
I use WiiFlow, by the way.

First, Call of Duty Black Ops.
It shows me the WiiZapper and the Adjust the strap screens, but then it goes into a black screen that says: "Loading" in the left bottom corner of the screen and it just freezes there. Is there... something I can do about it?

Then, Metal Slug Anthology
I can play Metal Slug 1 thru 5 well, but Metal Slug 6 doesn't work. It just shows a black screen and it freezes there too.

Here's my system check, if that helps:

EDIT: Nevermind; I found what options to select.
Thanks a lot.

Care to share? I ended up using CFG USBLoader to play through COD:BO (but, would like to get it working through wiiflow) and can't play any of the Metal Slug Anthology at all.

Edit: I take that back, CFG seems to be running MSA just fine... I don't get it, I use the same IOSs in both, as far as I can tell...
