and I have been tossing around the idea of fixing the state of SNES debuggers. Our previous debugger projects were FCEUXD and FCEUd, respectively (FCEUd preceding FCEUXD).
So far, I have been successful building Snes9x-gtk
on Mac OS X 10.6. Personally, I like bsnes better, because it builds cleaner, and with OpenGL support. Snes9x-gtk's OpenGL dependencies (gtkglext) do not build for "native" GTK; it requires X11. Even with X11, it builds, but the OpenGL support is broken. On the other hand, bsnes just works.
So, I'm considering using bsnes as the basis for an SNES debugger. bbitmaster might agree. bsnes already has a debugger, but I don't like it.
Anyway, here's some screenshots of both emulators (pretty much vanilla) running on OS X!
