I do not have the DOS versions of SPWW2 or SPMBT anymore so I can´t test as to why they would not work with DOSBOX. However if you run version 0.70 of DOSbox there is also a newer version 0.74 available.

Maybe it works better maybe not...
EDIT:
If I remember correctly SPMBT 3.01 was just a patch. You needed to have SPMBT 3.0 installed first.
Also back in the day there was a program called mousectl that was used by people having trouble with mouse cursor running the game from windows 2000/XP. Make sure not to use that mousectl thingy when running the game in dosbox. Try to start the game directly from SPMBT.exe or SPWW2.exe.
I did however have and uploaded SP2WW2 into here:
