Here’s where things get weird.
In MAME, CHD files are most famously associated with arcade hard drives. Games like Gauntlet Legends, Blitz 2000, and NASCAR Arcade (the actual arcade title from 2000) use CHD because their data lived on a physical hard disk inside the cabinet.
NASCAR Arcade (released by Sega in 2000) was a completely different game—3D graphics, sit-down cabinets, linked multiplayer. Its CHD file is large, complex, and rare.
Now, imagine someone searches for “NASCAR Arcade CHD” and instead finds NASCAR Rumble -USA-.chd. They download it, try to load it in MAME as an arcade game, and... nothing. MAME errors out. Confusion spreads.
In reality, the NASCAR Rumble -USA-.chd file is not for MAME arcade emulation. It’s for PlayStation 1 emulation (via DuckStation, PCSX-ReARMed, or RetroArch’s CHD-capable cores). NASCAR Rumble -USA-.chd
But because the file lives alongside arcade CHDs on Internet Archive and ROM sets, it inherits the mystique—and the misunderstanding.
Use chdman (part of MAME):
chdman extractcd -i "NASCAR Rumble -USA-.chd" -o game.cue
But why? You lose compression and gain no benefits.
Important: No, you cannot run this CHD in MAME as an arcade game. MAME will reject it because the CHD contains PlayStation CD data, not an arcade hard drive structure. Warning: Avoid "ISO" versions of this game
