@SimGuruModSquad: Custom group IDs

Not sure if the @SimGuruModSquad thing will work for you, since you are new. But now it will! =)

Ya know.. I've been around these forums since the orginals (for The Sims 1), and resigned up in 2009... I've got over 64 comments, which is minor compared to some, but I don't comment a lot, especially not "me too" posts.. so this limit of features thing really is annoying..

Which TypeID is this resource?

Inge: It's _IMG 0x00B2D882

Kuree: Yes, that's what I was reporting - the game seems hardcoded to expect a 0x00000000 group ID. :)

And you set the top bit in the instance ID to match the group, when you were trying with the top bit set? I have reaosn to believe the bit either has to be set in both or neither.... though how you can accomplish that when you have to hash something to make the IID I have no idea. For that good reason you may well be right. I am beginning to wonder whether it's not best to simply set the bit for the catalog resources and just do what we normally would do for the others.

I do set the top bit of the instance ID on, like so in C#:

ulong customInstance = FNVhash.FNV64(whatever text) | 0x8000000000000000;

Same for the group ID for all other resources:

uint customGroup = FNVhash.FNV16(whatever text) | 0x80000000;

(I use my own FNV hash class in case it looks unfamiliar.)

For all other CAS-related resources so far setting the high bit on in both the group and instance IDs works fine. Only the swatch images can't be found by the game with the group ID high bit set on - I really think there's a 0x00000000 group ID hardcoded in there. But the Instance ID high bit set on works fine.
