I was right: it really is
possible to have a quick look at the BS files (here the ones used in the PS1 version of Biohazard 2) you get when splitting the BSS into 64kb parts which then can be viewed with the Sony Music Converter.
To skip that process of obtaining the BGS this way, have a look at my Resident Evil Galleries
they are structured following the common BS pattern.
Now every room has a different number of room cuts ranging from only 1 to 16. You have to know where each room starts and ends (not very difficult if you have played the game and thus know how every room looks like) and the first
room cut of any room results in a 00
at hex offset 37C. The second
roomcut needs 01
, the 15th
and so on.What's it good for?
When you hex-edit any saves to have your player character appear in another room than the common save locations one often runs into the problem that (even if the coordinates are correct) the room cut displayed directly after loading is the wrong one and that you need to run around like a blind man until you enter the room cut shown and only then the camera trigger zones start to work and change the background images upon entering a new zone.
With this method above you can easily identify the room cut number you want to have your char start with and accordingly change the save game.
No more trial and error or playing blind man!
