So, only rooms 6b,4b,1b,0c have mimics, these are decimal rooms 107, 75, 27, 12, what matches your list Erock. Thanks

You can edit these 4 room values to set the mimics into other rooms, but more than 4 seem to be not possible without some asm.
E.g., you want mimics in room 212, this is hex: d4.
In room dec12=hex0c are no mimics, so you set at
snes $1E/C703 = pc  $0F/4703: c9 0c -> c9 d4

This will make stone cyclops to mimics in room 212

Could it be possible to separate this sprite into two different sprites so that Mimics could then be used anywhere?

Conn wrote:theoretically it is...
the sprite index (83 green, 84 red) is stored to 7e/0e20,x (x=specific sprite, 00-0f). The difference between rocklops and mimics is that the mimics also have a 01 stored at 7e/0da0,x.

Here's when I changed it to 00 in blue. However, this requires a lot of asm to point to the correct sprite. I'd stick to those 4 rooms, since it's really going to be complicated to code this for little outcome if you wanna change it.
