This change includes some cleanups, removal of mainargs.s (game console programs never have arguments), and a workaround for a problem I'm seeing. The problem is that sometimes (in fact, more often than not) the clrscr() call in testcode/lib/joy-test.c writes some garbage chars on the screen (most often a "P"). Could be my hardware (I haven't seen it on MAME), but to me the root cause is still unknown.
