I have been using my configuration for PearPC 0.4 an then using it on PearPC 0.5, however, a few seconds after booting, it crashes.

ppc_start_resolution = "1024x768x32@60"
ppc_start_full_screen = 0
redraw_interval_msec = 10
key_compose_dialog = "Ctrl+F11"
key_change_cd_0 = "a"
key_toggle_mouse_grab = "F12"
key_toggle_full_screen = "F11"
prom_bootmethod = "auto"
prom_env_machargs = ""
prom_driver_graphic = "video.x"
page_table_pa = 0x00300000
cpu_pvr = 0x000c0201
memory_size = 0x40000000
pci_ide0_master_installed = 1
pci_ide0_master_image = "D:\Mac OS X Emulation\Macintosh HD.img"
pci_ide0_master_type = "hd"
pci_ide0_slave_installed = 0
pci_ide0_slave_image = "C:\Users\Student.2018STUDENTLOAN.009\Desktop\RealtekRTL8100-V2.0.1.iso"
pci_ide0_slave_type = "cdrom"
pci_3c90x_installed = 1
pci_rtl8139_installed = 0
pci_3c90x_mac = "de:ad:ca:fe:12:34"

I would consider using Qemu to emulate PPC OSX. It might not look as fast, but it is stable.
I assume (not sure) you can use your current disk image with OSX with Qemu as well.

Is the performance drop due to emulation or the version itself, Cat_7?

The performance of which?

PearPC 0.5 rolled in the speed improvements of the 0.4 Redscorp build as well as a few emulation improvements. It hasn't really been worked on to stay current with requirements for a modern OS, however.

QEMU emulates more, and does it more accurately, which comes with a performance cost. But it also results in things generally working as expected (with floating point, audio and accelerated video being the three major exceptions, which are still improving, but are not there yet). It also means that you get some semi-functional features (like audio and some video acceleration) in QEMU that were completely sacrificed in PearPC for speed.
