Hi All,
Great forum here, tons of good information that has helped me out in the past numerous times.
However I currently have a problem at hand that even this forum does not offer a solution for. Over the past few months I started expanding my old Win95 PC with all the hardware I could never afford, just to replay some of the classics. I set up the machine so I can boot FreeDos, Windows 95 and even legacy Dos 6.22 just for the really odd games. The game from the thread title, Jurassic-Park by OCEAN, is one of those. I have the hardware setup *perfectly* in all operating systems, every game I throw at it just works EXCEPT this Jurassic-Park. It really refuses to play the sound effects. The music works fine when played through an external Roland device, it does not work when played directly through the card (soundblaster option). I really want to get this working since I think it is a very cool game.
The sound card I'm using is an AWE32 CT2760 (the jumper card). IRQ's are 5 1 5 and the address is 220 (just the defaults). I also have 8MB installed but the MIDI part is not used since I have a physical Sound Canvas connected to the gameport. The card is of course initialized in config.sys and autoexec.bat (aweutil etc.) As mentioned before, vitually all games I have (which is a lot since I collect them) work fine with these settings. What I observe in JP however, is that in Dos 6.22 some really distorted sound comes from the card (more like small cracks in the speakers) and in FreeDos and Win95 there is no sound at all. This happens when Soundblaster or Adlib is selected in the setup of the game.
I read that the game does not really rely on the OS and pretty much uses the hardware directly. So I replaced the AWE32 with another SB16 compatible ISA card (Advanced Logics ALS 100+) but the issue remains.
When I select Roland devices for sound effect (not music) the game simpley crashes and even needs to be reinstalled.
(I bet there is some really nasty code under the hood of this game!)
I tried many different IRQ/setup/.. configurations but none of them seem to make the soundblaster effects work. I read in the manual that "sampled effects" are used when there is enough memory. I have plenty of RAM so I guess the game uses these sampled sound effects.
At this point I have no more ideas so I was hoping maybe some of you guru's here have an idea or had to deal with this game before.
The rest of the system sepecifications are:
ASUS sp97v7
Pentium 200MMX (clocked at 225Mhz)
SiS onboard video (4MB)
92MB EDO RAM
2GB FAT16 partition (the rest of the 3.2GB is hidden)
Any help is appreciated.
