1st Post: Assistance Required (All The Above)

I have been in the game scene for a long time now...since the old Apple 2 days.
I just started to get into the PSP scene and I am looking for help to run emu's.
I currently have firmware 2.5. So far I see no downgraders that are correct yet? Am I right?
If there is, how is it performed / installed?
As for the ROM thing, im covered fine. I own over 5000 real games!

Anyhelp would be great to this old newbie here.
Thanks!

I would love to see a Sega CD emu other than a PC one. :rolleyes:

not yet although there is a promising exploit around here somewhere
thats a mighty collection
