If you are using a newer version of MAME with an older "split" or "merged" ROM set, your Capcom games likely won't work because they are missing the updated QSound dependencies. Device Sets: In newer versions, MAME may also look for a specific device file called qsound bios

Embedding QSound in the BIOS allowed motherboard manufacturers (e.g., Intel, ASUS, Acer) to offer “enhanced audio” without a dedicated sound card.

However, if you're using a modern operating system, you may want to explore alternative solutions that offer better compatibility and support. If you are using a newer version of
