Qsound-hle.zip Rom -

If you are using a MAME 0.139 ROM set from 2010, qsound-hle.zip did not exist yet. Those old sets require qsound.zip (the LLE version). Mixing a 2024 emulator with a 2010 ROM set will cause errors. Always match your qsound-hle.zip version to your emulator’s year. Newer emulators only accept the HLE version.
