A bootleg was added to 0.221. It is about 50MB less than the original, but it works without needing the parent rom. Why is it so much smaller, and is it missing anything?

The original machine roms are encrypted and the bootleg is largely unencrypted. There are also other parts of the romset which are not double data filled halves but are actually smaller roms, as well, leaving the overall romset smaller and not easily compressed.

Thanks. Has anyone seen a Slug 3 bootleg? The original is only slightly smaller than Slug 5, so a much smaller boot would be great if it works without the parent like the boot for Slug 5 does.
