2001a Slim + Evilnat 4.90 noBD - No Drive at all - Won't boot ISO or Games

I have a 2001a Slim that has no BD. This is my first time dealing with custom firmware so, maybe I missed something important.

So far I can only run games I install from PKG files, but games I FTP to the HDD Games folder will not boot from anything I have tried. Multiman, Irisman, and Webman. They show up and pass all tests and I can even install updates for them but, they all go to a black screen then just dump me back at the XMB when I launch them.

ISO files will show an error...
