I do have a working Starcraft profile, and I have played it already a while back, so I can confirm it’s working (or was working at least).

Larrynho’s suggestion is a good one, that might already solve your issue with minimal effort. Game mode is dead useful in 3D games, but absolutely useless in 2D applications like Dosbox. You don’t gain a single percent of performance, so it’s best to exclude Magic Dosbox from the games list (Game Launcher on Samsung phone).

If that doesn’t help, the solution might be in Magic Dosbox’s built-in mouse fixes for Windows 95.

Try this:

– Once Win95 has booted up, press the back button of your phone, so the Magic Dosbox menu pops up.
– Go to Advanced settings, and select Manual correction.
– set it to match your Win95 and/or Starcraft resolution (most likely 640×480)
– also, set the Correction type to “msmouse”, that’s mandatory in Win95/98.

Or, you can download the profile here. I’ve never uploaded it here, because it’s not finished, but it should do the trick.
Be aware that it’s using Expert settings, so you’ll have to adjust the mounting commands.
