My setup is to run ResEdit with NovaTools in OS 9 under SheepShaver on my Intel MBP. A major advantage there is the emulator runs in a window. There's a pre-configured version of SheepShaver called…that comes with a version of OS 9 already. There might be newer and better versions by now, I don't know.
It was a little tricky to get it up and running but if you follow the instructions and let me know of any difficulties you encounter I can try to walk you through it. The hardest part is getting StuffIt Expander installed within OS 9 under SheepSHaver. Then you're pretty much set.

Reason for edit: Much as I sympathise with the goal of keeping these tools available, Apple's copyright remains valid, and I can't in good conscience allow the directions for finding Mac OS 9 online to stand.
