Recently, I came across a video on Youtube by Linus Tech Tips about the PCEm emulator that I found to be cringy and ill-informed. As a computer engineer by education let me explain few core concepts on how emulation works.
You mention "Pentium MMX CPU" a few times in your post, but fail to mention any FPGA solution that can emulate a machine of that class. MiSTer can't do that, the best it can do is a 486 (not just missing MMX, doesn't even have an FPU).

The last processor generation it worked on is the 486, but on a Pentium or newer it always fails with a “Debugging is not allowed” message.
I guessed the reason for that correctly - prefetch queue. Mentions of CUP386 in the comments also brought back more memories of the cracking scene in the late 80s/early 90s. There's some very interesting discussion on SMC vs CPU behaviour here --- in the context of an open-source 486-level SoC core:

I installed mac version of PCem and then I put roms and its says there is no roms how do I fix this?
I got the roms from this website:https://github.com/BaRRaKudaRain/PCem-ROMs

Roms download link : https://github.com/BaRRaKudaRain/PCem-ROMs - PCem needs these rom files(hardware configuration file) to work, download the rom files with the folder structure, directly overwrite the items in "roms" folder of your PCem installation. Good luck!
