I'm glad you got some use out of it.
Did you try with less cycles? Depending on how fast your CPU is, less CPU cycles leaves more time for the graphics and sound, the most basic VGA 256 color games can run as low as 1500 cycles, just a balancing act to find the best setting for what you want to run.

In the dosbox.conf file under the mixer settings you can play with:
rate=22050
blocksize=4096
prebuffer=100

Lower blocksize and prebuffer settings might reduce lag at the risk of more stuttering, and rate at 11025 might sound slightly worse but have better performance.

Also what Sonnet settings are you using?
DisSigBounce and less often EnStackPatch can make a big difference in performance.

Someone start a gofundme or some other bounty so we can hire someone (not me) to finally make a PowerPC (or 68k?) JIT/Dynrec CPU core.
