Troubleshooting

SheepShaver doesn't boot

SheepShaver should boot all MacOS versions >=7.5.2, except MacOS X. However, your mileage may vary. If it doesn't boot, try again with extensions disabled (by pressing the shift key) and then remove some of these extensions: "MacOS Licensing Extension", Speed Doubler, 68k FPU extensions and MacsBug.

The colors are wrong in 16 or 32 bit graphics modes

If you're running SheepShaver on a something other than a PowerMac, it may be that 16 or 32 bit graphics modes show false colors due to the frame buffer being little-endian. Apart from patching the X server, there's unfortunately nothing that you or SheepShaver can do about this.

Full-screen mode doesn't work

Some X servers on Linux PPC don't support DGA and full-screen mode cannot be used with these (in this case, you should disable it in the "Graphics" settings). If you are seeing a message like "cannot map /dev/kmem (permission denied)", you have to either run SheepShaver as root (not recommended) or give yourself appropriate access rights to /dev/kmem if you can login as root.

Ethernet doesn't work

SheepShaver crashes, but yesterday it worked

Try the "Zap PRAM File" item in the main menu of the SheepShaver preferences editor. When you are using a ROM file and switching to a different ROM version, you have to zap the PRAM file or SheepShaver might behave very weird.
