That sort of thing is almost certainly a behavior of the game, or perhaps of Windows, rather than an issue with DOSBox. Perhaps there is an option to "hide" or otherwise not show the menu bar. For example, the menu appearing only when the pointer is moved to the top of the screen.

In SVN with machine=ega, reducing cycles to 500-600 range reduces flicker in the intro substantially.

You may find that Reaping the Dungeon looks a bit better with the machine=vgaonly setting in DOSBox, as it displays 9-dot wide text as real VGA does, so that the alphanumeric characters have gaps between them.

The guidance I offered is for official DOSBox (0.74-3 or SVN) but may not work for forks. The cycles=10000 setting prevents stuttering on my system; however, you may need a lesser or greater value on your system.

Seems to work fine in DOSBox with default settings except: machine=vgaonly, core=normal, cycles=10000. The vgaonly machine type is needed for water to look as it should, and the core and cycles are needed for the sound to work. Of course you should also run the game's setup and enable SB sound with …

Sargon III supports light pen. It uses function 4 of INT 10h to read the pen, so perhaps it would be useful to test around that function of the BIOS.

Longer command lines are accepted by the internal shell, which can handle them -- and this is very useful for multi-image mount commands that can be long indeed. However, the command tail that is copied into the PSP is predictably clipped to what can fit when executing DOS programs.

Real DOS returns an error code to the calling program when memory allocation/deallocation functions fail due to a corrupt MCB chain. However, the system will likely be halted if/when the program tries to exit back to DOS with a corrupt MCB chain, where there will be a message like "Unable to load …

If the COM file is assembled and linked correctly then the first three bytes in it should be the near jump to the CLEAR_SCREEN procedure. However, the 200h entry point you mention suggests you have made something other than a COM format program file, because DOS (and DOSBox's internal emulation of …

The VGA version, BLOCK.EXE, uses some PIC resource files that the other versions do not use.

If it's known to work in enhanced-mode Win3 with Win32s (which only supports a subset of the Win32 API) then try the cputype=486_slow or cputype=pentium_slow setting in DOSBox, and maybe memsize=31 if it's from the late 90's.
