I've release a precompiled version only for G5 of SDLMame 0.108u5 and SDLHazeMD 0.07a and can found on Mamechannel . For the moment can found only SDLMame. If anyone want a G4/Intel version or suggestion/other, just ask.
nf_: if you link directly to a disk image on my site like that, you will get screwed when I remove an old version. You're better off hosting the file yourself or linking to http://vastheman.com/download/#macos10 and telling people to look for it.
