displays the warning:

after pressing "ok" dolphin displays this:

"Warning" Illegal command 05, CPBase: oxoo54d920 (it lists about 15 similar
messages.)

after pressing "ok" a second time, these 2 warnings loop over and over
again and never end.

Please provide any additional information below.

on another note, Dolphin used to be able to run metroid prime 1 almost
flawlessly and a very good speed (this was around revision 1000, 1500, or
so. i don't remember exactly. anyway, Dolphin is currently having allot of
trouble running Metroid Prime 1 at a decent speed. it's certainly MUCH
slower than it used to be.
