I usually rip with ImgBurn.

I used CloneCD to rip my SotN CD.

I'd ping over to GameFAQs or something, download a save file there, and use something like Dexter to convert the memory card to .mcr format.  From what I understand, pSX handles both.  And it should, because I'm pretty sure the only difference between a .mcr and a .bin memory card file is the extension on the file.  So a pSX memory card file can be imported into ePSXe as well.

Someone correct me if I'm wrong here.

I am a bit puzzled by this as well.

I needed that late game save because there are a lot more prices in the table in LIB.BIN than there are items the librarian currently sells.  There might be more items than the librarian sells, period, which makes me wonder if there is more stuff in the PS1 version that exists, but can't be accessed.

You can find it yourself by searching for "a0 0f 00 00 00 05 6f 00" in LIB.BIN.  I'll make a spreadsheet once I identify where the table starts and ends.  This isn't what I was looking for, but it's something no one knows yet, so I may as well document it.

Castlevania:SOTN\\
F_MAP.BIN - Canvas Size="16x31".  The map.

\\BIN\\
WEAPON0.BIN - Canvas Size="16x31".  Animations for shields, attacks, punching, weapons, and a bunch of other cool stuff.  If anyone figures out how to properly view and load the palettes, then we could make some awesome wallpapers of Bat Pentagrams and such.
WEAPON1.BIN - Canvas Size="16x31".  More animations, including some duplicates from WEAPON0.BIN?
RIC.BIN - Canvas Size="4x31".  Rictors animations, and other stuff.

DEMOKEY.BIN - Canvas Size="16x31".  No clue.  Music?  Instruments?
