Help with old CD-ROM

Okay I just found one of my favorite old games for Mac- Pajama Sam! But it's not letting me play it, is there anyway I can avoid this? I'm on an Intel MacBook running OS X 10.5.2. Please help, I want to relive my childhood!

You need some sort of OS 7-9 emulation on that intel mac
