Hi Amon91 !
PearPC may not be dead, but it didn't get any official development since almost two years... Apple has chosen to build Macs on X86 architecture. PowerPC is no more for general public, hence its emulation on other platforms has lost interest.
The worst sign of agony is PearPC's developers and most talented contributors have all gone to OSX86
I'd really like to fiddle with PearPC's code, but I don't have any programming skill in C, C++ and assembler
