RE8 enemy swapping tutorial

So I had been digging through the demo in an attempt to try and change the enemy spawns, and after a few tries I was successful in replacing the daughters with Lady Dimitrescu link to this demo mod



so how did I do it?

well it's straightforward but it seems to have some limitations right now.
you'll need to have extracted the game/demo files for this (that's step 1)
link to info/tools to extract and modify the pak file(s)

once you've extracted the game files go to this folder in the game files:
re_chunk_000\natives\stm\spawn\enemy\data

this is where you'll find the data for the different stages/enemy spawns

for this tutorial I'll just demonstrate how I made my "Lady Dimitrescu replaces the daughters" mod for the demo.

this folder will have a few files. the ones we're interested in is the ones that end in "spawnparam.user.2"
(the folder is named slightly different in the full game, but the spawn files still end in "Param")



opening up one of these files in a hex editor will look something like this:



this looks like a lot of data but it's a pretty simple edit, we actually only need to make some small edits.

near the bottom it says "e.m.1.2.6.1."
this is the enemy being spawned by this file, in this case em1261 is one of the daughters. Specifically: Cassandra.

so all we need to do is replace it so it now says "e.m.1.0.0.0." to make it spawn lady Dimitrescu.
save the file and create folders for the mod manager to have the mod be installed in the right location.

test the mod and it should work:


now for the current limitations/issues:
- special enemies like the daughters/Lady DImitrescu seem to have some sort of limitation that they can only be spawned once per checkpoint area.
(however you can spawn all three daughters and Lady Dimitrescu in the same area)
- spawning Lycans (the basic enemies) over the daughters doesn't seem to work
- spawning characters in other "chapters" doesn't seem to work. meaning I was unable to spawn Lady Dimitrescu/daughters in the village demo.
- Pathfinding might not work correctly for the swapped enemies
- replacing story characters with other characters will make their audio/voice clips during cutscenes/events no longer play.

stages are grouped as follows:
C02_1 - village
C02_2 - castle
C02_3 - Beneviento area
C02_4 - Moreau's area
C02_5 - Factory
C02_6 - Village again?
c02_7 - Ethan meets Miranda (cutscene after mutated Heisenberg fight)
C03_1 - Chris section
C03_2 - Final section of the game as Ethan
St01 - Ethan's house intro
st03 - Castle
st06 - Factory

Here's a list of enemies so far which you'll need for swapping and knowing what enemy is which:
