Hi Scali,
A very good first attempt, I hear music from the IMF.DRV and my FB-01. Unfortunately there are a couple of problems.
1st, the patches have a difficult time transmitting correctly in DOSBox, regardless of version. Ripsaw8080 made a patch for FB01.DRV, but not IMF.DRV, that allows successful patch transfers from DOSBox to the FB-01 via a USB. Every game has IMF/FB-01 patches, so to get a successful patch transfer, I have to transfer the patches via FB01.DRV and another version of DOSBox, then go back to yours to run the game. But this assumes that there is an FB01.DRV that works with the game, and not all games have an FB01 driver.
2nd, sounds are often, but not always, incorrect. Here is a recording of a real IMF vs. the emulated IMF. Note that there are percussion sounds heard with the IMF.DRV that are not transmitted via FB01.DRV.
Compare this (real IMF in a 486) :

against this (Scali's DOSBox emulation) :

A great start however!
