latest version of musashi engine
includes floating point emulation
(plus a few patches to add in missing opcodes needed by ack - see tags JFF & TBB)
added a few missing linux syscalls in sim.c
pascal now runs pretty well
quick test with modula2 passes
c gets the floating point numbers wrong, so more work needed here
other languages untested
plat/linux68k/emu/build.lua is probably not quite right - the softfloat directory is compiled in the wrong place
