I can't duplicate
Windows 7 - 64 bit - Binary from
I tried command line:
mame64 nes jparku
and also through the UI by simply launching MAME64, selecting the NES console, selecting the game from the software list.
Both times, I booted the game and was able to start and play without issue.

Your OS is listed other OTHER, I assume some flavor of Linux? Where did you get your distribution/binary?

Binary from the official site x64 version, downloaded this morning. The O/S is Windows 10 x64, not listed in the dropdown so I chose other. Let me try with x86 MAME.

I used the built-in gui to launch. When I use the command you used, I get this:

Seems the issue lies with the FE I used (Negatron). It modifies the mame.ini to add paths etc. If I used the mame.ini from the mame folder that this FE pointed to, it breaks. A new clean .ini fixes the issue. Thanks for taking the time to investigate. I've attached the mame.ini that breaks it. Odd that jpark loads fine, but jparku not. I'll take it up with the FE dev.

The stack crawl also indicates you have cheats enabled at runtime. When dealing with roms that don't load or crash, this should be the first thing you shut off.
