Bryce 5 crashes SheepShaver on my side immediately. Host OS is Sierra.
My guess is that the not completely emulated MPC 603 in SheepShaver is incompatible with a app made for MPC 740 (or better) Macs.
Not uncommon as the specs for Bryce 5 are Mac G3 or G4.
Good luck with your Windows VM!
I would like to recommend XP or lower in VMWare Fusion, as Fusion offers a DirectX 9 compatible GPU emulation.
VirtualBox does not have a GPU support that I´m aware of.
I may have a pre-built W2K or XP instance for VMWare already uploaded to Mega.
Let me know if you should want to try - setting up things yourself is part of the fun though.
Snow Leopard does run Bryce5 too, due to the Rosetta PPC emulation.
Windows 10 64bit can run the app as well, albeit in the small Bryce5 (800x600?) screen on a black background.
