Frequently Asked Questions

Q: Can I use a modern MAME 0.200 BIOS pack with MAME 0.78?

A: Rarely. Newer BIOS files often have different internal ROM names or compression (LZMA vs ZIP). For example, the 0.200 neogeo.zip uses neo-epo.bin but also includes neo-sma.bin which MAME 0.78 doesn't expect, triggering a "too many files" error. Always use a version-specific pack.
