Let me preface this with the following: If you’ve already installed DOSBox 0.63, you don’t need this. Please don’t waste my (relatively tiny) bandwidth.
As I’ve had to restart, I’ve had to rebuild virtually every aspect of DOSBox’s shared libraries, headers, and some OSX tweaks. This build has no AltiVec enhancements, and is built for a G3 target with XCode 1.5 (MacOS X 10.3.9, specifically.)
Anyway, if you want a MacOS X friendly DOSBox build, here it is. Please read the files included with the binary; they will answer most of your inquiries.
