loving the RE1 port and was really excited to hear the save room theme when I entered the storage room but...nothing. Is that normal with this version of the game?

--- Precisely that "East storeroom" is one of the few save-rooms that simply don't have any music in all versions of the game.

No, the original PS1 version has music. I always liked getting there, it was warm and soothing.

Here is a timestamp to a long-play for the Playstation NTSC-version to "East Storeroom"; no music.

So what "original PS1 version" you're referencing to?

Probably just bad memory.

You can also easily confuse both base floor save rooms in the mansion.
