Can you tell me exactly how (from command line) you are loading this and what machine are you using to do so for I can see it working in 0.211 and not working in current? Also, are there additional steps needed to start it or is it something autobooting?
I did note that in current hashes, the image itself is listed as not working (preliminary) in ibm5150. Are you sure since there is a lemmings entry in both ibm5170 and ibm5150, it isn't confusing them?

I'm using the machine [at386] with 2 floppy disk drives and one hard disk The game isn't autoboot, you need to start the machine with a hard disk with MS DOS or a MS DOS disk inserted. those are the slot devices that I have configured:
# SLOT DEVICES
The game was added wrongly to the ibm5150 software list in this last MAME version, I commented that on the PR (because it is already in the ibm5170).
I added the game in the ibm5170 software list, on the MAME 0.206 version and it worked until 0.211.
From 0.212 the game shows the message that the floppy disk needs to be inserted in the drive.

|It's likely that https://github.com/mamedev/mame/commit/def5ea3da15d2cf21474bdaeb97f9979a332fe71 caused this. I think that only OG is going to be able to fix it.|
