I have been doing some research into what happens to existing installations when you install a new EP, in the right order or the wrong order.

I have noticed that later EPs seem to include objects from earlier EPs, as they come off the CD even! But if you don't have the EP, they don't show in the catalogue when you're playing.

Does anyone know where the flag is stored that defines which EP an object is meant for? Or how else the game decides not to put it in the Buy catalogue. I can't see anything obvious in the OBJD.

I am trying to understand how all these things fit together to help with the design of the PSJE plugins, and would not use the information to dishonestly make objects available to people without the right EPs. Mail me [email protected] if you don't want to post the information publicly.

TIA

These flags are stored in OBJD, Unused - dynamic sprites base id (Sims1).

0x01 - Original
0x02 - Uni
0x04 - NL
0x08 - OfB
0x10 - FFS
0x20 - GLS

Thanks very much Shy, I bet quite a few of those fields have out of date labels now
