I don't think so? But the ICD1 should work, though I haven't used it a
lot. If you have an ICD1 then download latest gpsim and try it. Adding
-d /dev/ttyS0 should be enough. (I don't think it has been used much,
so there are probably still issues to be worked out)

I have no idea if gpsim can make use of those files. JAL and sdcc
can probably work with some changes (adding a NOP as first address).
Then you'd get high level source browsing. However, only one-byte
data types is supported in gpsim. (I.e, a 16-bit integer shows up as
two separate bytes in gpsim.)
