OK, this is silly, and I really should know this, but....

How do MAMEDev know the size of the samples before they are dumped?
obviously MAME expects these files based on CRC's or something, but if
they are undumped how do you know the size?

Samples don't have size entries in MAME's database.

Ahhhh.... Thanks Roman, I *knew* you'd be the one to answer that one. I
assumed as much to be honest, but I wasnt sure..

Can I assume it just looks for the correct name under the game path in
the samples folder? Me imagines me going 'pow pow pow' to galaga ;-)

:-) To be honest, it was one of the first thoughts that popped into my
head when I read about the samples... That or ol' Rossi was keeping it
to himself with his bootleg rafelesia :-)

Yes, the only information on samples in the mame source is the file
name, nothing else. That cames from the facts that samples aren't
dumped (i.e. extracted from a digital storage device) but recorded.
As such there is no reference version (and sample dats are beyond
stupid).

That's also why we push for the discrete system. Since it describes
(or tries to) the actual workings of the analog setup, it is a
reference. Having it actually produce sound is almost a side effect :-)

OG.
