Overall Lemmings 95 works well on Windows 10 but the scrolling messages on the main menu and the fast-forward feature in-game run too quickly. Perhaps they are tied to the frame rate.
Also, are there any additional level packs for Lemmings 95?
Hi vatten,
Welcome to the Forums! 
I never played all of Lemmings for Windows 95, but I have played some of it to know that fast forward is way too fast on modern machines such that you don't ever see the lemmings make the long walk in between and upon engaging it it will simply end the level. AFAIK, there has never been a patch to address this. Thus, fast forward works properly only on very old, slow machines. For that reason, it is advised that you don't engage FF until you have all of the path ready AND you're absolutely certain that the crowd won't get into danger along the way. Obviously this is where it would help on those levels where there's a lot of building involved, but unfortunately you won't be able to engage it even once while playing those levels, or any level for that matter.
Hello
There is some common interest in this stuff from the vintage computing community. It seems Lemmings 95 may have been tested for a 486dx-33 as on such a machine the fast forward runs at an appropriate speed. If you can use a hex editor and your LEMMINGS.EXE is the one is the one dated Jan 15th, 1996 and is 133,120 bytes long you can patch it yourself to run fast forward mode at 2x speed instead of as fast as the computer can go:
at 0x3251: change 75 1C to 90 90
at 0x32c1: change 74 to EB
at 0x2b42: change 64 to CC
at 0x2b46: change 00 to 50
at 0x2b51: change 64 to CC
at 0x2b57: change 01 to 78 [for double speed. or use 65 for 1.5x speed]
at 0x2b59: change 64 to CC
