https://en.wikipedia.org/wiki/Unreal_mode You can read in that article that Ultima 7 uses it, and that game works in DOSBox. So, yes, unreal mode is supported. However, if you refer to "huge real mode", that is not supported.

I ran the patch found here and started the game with "ultima t" which I read somewhere starts the game in Tandy mode. When I do that, I do get more colors, but every other "line" on the screen seems to be missing or black. That is the typical "venetian blinds" effect when trying to convert Tandy …

With the machine=cga setting there is an internal line-doubling scaler on 640x200 modes, which includes mode 6 graphics and text modes. The internal scaler overrides any user scaler setting (even "none") and can't be disabled.

Are you mounting a C: drive? I ask because I can reproduce the "Divide error" you describe by not mounting a C: drive. If you are mounting a C: drive, then perhaps there is some problem with it, such as insufficient access rights to the folder being mounted.

So, to answer your question about DOSBox, both devices are supported. The SS is actually based on the ST, but also has an added FIFO …

Text mode in CGA is scanline-doubled, and the internal scaler that doubles vertical resolution takes precedence over a user scaler. The typical solution is to use output=opengl and glshader=sharp (or your choice of shader) in SVN instead of using a scaler.

I suspect you may be referring to the blank display line added by DOSBox's internal shell, which does differ from other command shell implementations but is a purely cosmetic choice and not really an issue. Pressing enter at the prompt should display: Z:\> Z:\>_ Perhaps you are instead seeing: Z:\> …

SBPro 1 & 2 and SB 16 have a mixer feature that allows a game to adjust sound device volumes. By default, the SB mixer is connected to the DOSBox mixer (sbmixer=true), but this can be disabled so that a game can NOT change the volumes. However, what is not readily obvious is that while SB16 is …

It's a bug in the floppy and CD-ROM versions of Superhero League of Hoboken. The game chooses not to play some of the MT-32 MID files stored in the MUS file because they have too many tracks. There are three MID files affected: two are easy to fix with a simple hack, but fixing the third is …
