I get a black screen after the start menu in dosboxpure, staging and vanilla dosbox. tried lowering the cycles but i dont see the squiggles. did watch emmfoolery play it looks fun!
The best game experience for running SINEBYTE for DOSBOX is running the QBASIC 1.1 Interpreter with the SINEBYTE.BAS source code instead of running the executable (which is based on the SINEBYT2.BAS +custom timer).
