The core of the issue lies in the arcade hardware. Unlike its predecessors which ran on SNK's Neo-Geo MVS hardware (which MAME 0.139u1 emulates perfectly), Metal Slug 6 was the first in the series to use Sega's arcade system. The Atomiswave board is technically a Sega Dreamcast in a cartridge-based arcade format, making it significantly different hardware from the Neo-Geo.
If your specific hardware setup struggles to process the Atomiswave system cleanly through legacy MAME 0.139u1 code, the global arcade emulation community highly recommends utilizing the emulator core via RetroArch. Flycast is engineered specifically for Dreamcast/Atomiswave architecture and handles Metal Slug 6 with less operational overhead than early MAME codebases.

The file is typically named awbios.zip . For the ROM to work correctly in MAME 0.139u1, both mslug6.zip and awbios.zip must be placed inside the same roms folder.
