Firmware emulation on a 2.50 psp...

Hey, sorry if this is the wrong section. or anything else... but I was highly curious if there is something that will allow emulation of firmware such as 2.60+ on a psp 2.50. Now, yes I COULD downgrade, but I already bricked my other psp... I don't want to again... Anyways, yes I DID search for a program, I googled for hours... sorry if I just fail at looking >.<. It would be so helpful and much appreciated if someone could help me or tell me of a program that would allow me to do this. Thanks so much in advance.

update to 2.71, get Homebrew Enabler (HEN) and get devhook .46. then you have 2.71 and you can emulate lower firmwares. including 1.5.

Ohhhh! I get it! Since it will be 2.71, I'll be able to run the UMD along with my homebrew! Thanks so much, I very much appreciate it.
