yaroze runs all of it, from the package to the disc, in one step, and yaroze run plays the disc in a window as well. Each step is also a tool of its own, named on its right, for a build that wants only one of them.

A Net Yaroze program is only half a program: the rest is libps, the library the Net Yaroze boot disc leaves resident in RAM. eco2exe combines the two into a standalone PSX-EXE, so the result boots from an ordinary disc in an emulator or on a console that plays burned discs, with no Net Yaroze hardware involved.
