I'll have to follow this topic. Seeing Indy/Buffy crossover stuff makes me wonder if this would apply to the Star Wars: Revenge of the Sith since it's the same developer and same platform.

did it use the slayer engine?


****EDIT****
nevermind, just checked it DOES use the same format

pak files have changed though/// buffy pak extractor bms won't read them

and seems to do things a little different, doesn't store temp files to the HD so nothing in cxbx is stored in the emulated HD partition

I believe that Silent Hill Homecoming is also based on a modified version of the Slayer Engine - i think it was one of the later games developed by The Collective before they became Double Helix Games.

the Contents Under Pressure pc engine is a no go, they changed the texture formats (st instead of mtx) so they are complete unknowns...some of the st's look like simple header files without any textures in them...and the texture names are no longer listed inside (likely they are now compressed or encrypted)

Hi Medievil, I was just wondering if you managed to make any progress on this project, or is it on the back burner for now?

DOA.. there is simply no way to get the buffy animations to work on the indy engine, it won't take them because they were made with a different version of the engine, and without the original source, no way to convert them...
there is other hope though.. cxbx-r is getting further along, you can actually play the game (missing character's at the moment, but the shadow is there so you can see where you are)
they are currently working on a number of things, like proper cpu emulation which will greatly increase compatibility and help with speed.. and they just moved form dx8 to dx9 (xbox and pc dx8 were pretty different, pc dx8 lacked many things..dx9 has more stuff and much better shader support).. it has been stated that even in it's current state, once they add a proper vertex cache system, speed will jump way up as thats currently the biggest thing slowing it down

Its getting there! Funnily enough without having read your latest message, I tested the game a few days ago with the latest cxbx-r and I too was pleasantly surprised. Good to see :)

it is playable now, with a not currently public/merged into main build...it has a few slowdowns (Will disappear as the emulation gets better) but overall plays pretty nice(I get, besides the occasional slowdowns, 29-30 fps [30fps game])

I'm not sure if this helps, but i think that some old games, might be using / reusing the same stuff as Buffy, in one form or another, whether it's texture, or sound effect, or animation.

1. Xena Warrior Princess [PSX 1999]

2. American Mc Gee - Alice [PC 2000]

3. Clive Barker's Undying [PC 2001]

4. Harry Potter and the Philosopher's Stone [PC 2001]

5. Harry Potter and the Chamber Of Secrets [PC 2002]

Each game was released by EA games.

There are many similarities in all of those games, not on first glance, but i've replayed them all, many times, so i know what i'm talking about.

I believe that Xena game engine could be the early blueprint for the Slayer engine.
I might be wrong though, but if anyone here is interested in my theories, i can share my ideas.

I'm writing this, because, maybe, just maybe this could help in one way or another, in porting Buffy The Vampire Slayer to the PC.
