-It is okay to remove all EM files for most stages.

-As in RE5, you only need to change the second id (ie, uEm1000) when changing characters around.

-When swapping enemies around, it's sometimes necessary to move entire em files instead of em IDs. I think they require many of the variables specific to enemy types.

-Byte just before "80 01" for first entry defines how many entries there are in file.

-5 bytes before the first ID string for an entry is the entry num for that entry.

-0xD5 after "uem5000" is the health?

-em20 in s105 as reference: (all are after uem5000)
--0x101 - mLife
--0x11D - mModelType?

-em09 in s0303
--Has a BSAA soldier setup in a way that it follows the player around
