I currently have DoomPSP v0.04 sitting on my desktop, waiting to be installed on my coming PSP (It's coming on Tuesday.)
I'm going for 2.0 FW, as I'd like to have the official web browser and various other goodies. I'm not that big on homebrews, so SNES9xTYL v.02, PSPChess and DoomPSP will be probably the only homebrew items I'll put on my PSP.
So, will DoomPSP v0.04 work on the 2.0 Firmware version of eBoot?
