Always scan downloaded executables. The safe path is to download the ROMs only and run them using the official MAME 0.130 executable compiled from source, or the completely open-source MAMEUI 0.130.

💡 : To get CHD-based games working, you must place the .chd file inside a subfolder named exactly after the ROM zip file within your /roms directory. For example: roms/nbashowt.zip (The main ROM) roms/nbashowt/nba_nfl3.chd (The CHD file)

– the last version before MAME’s ROM management became more complex (but also more accurate). For retro arcade enthusiasts running older hardware or maintaining legacy setups, the 0.130 ROM set remains a reliable, well-understood snapshot. However, for anyone building a new arcade cabinet or seeking the best accuracy and game support, modern MAME (0.250 or later) and its corresponding ROM set are strongly recommended. The 0.130 set is best viewed as a historical milestone in the ongoing effort to preserve arcade gaming history.
