The go-to choice for cheap S905/S922X chips, delivering superb arcade emulation via this core.
If a game runs slowly, try disabling any Run-Ahead features or other latency reduction options. Some particularly demanding games—such as —are noted to "require a fast system" and may have "video and sound issues remain" even on capable hardware.

Similar to full non-merged, but games that require an external "BIOS" file still need that separate BIOS zip file in the same directory to boot.

This is the most common mistake. MAME requires the ROMs to remain in their compressed .zip format. Do not extract the files. If you see a file named pacman.zip , keep it exactly as pacman.zip . Some particularly demanding games—such as —are noted to
