Problem Running Jump Raven in Emulation

I've got what seems to be an odd problem. I've had a Sheepshaver OS 9 set-up for some time, but as Cyberflix classics Lunicus and Jump Raven don't like that OS, I finally got around to setting one up for OS 7 (I'm running the freely available 7.5.3). Lunicus works swimmingly.

I feel certain that Jump Raven would also work, but I just can't get Sheepshaver to recognize the disk. I've a physical copy of the CD as well as the .img file available here on the Garden. OS 7 just wants to initialize or eject the disk when the physical CD is in the drive, while if I mount the .img file with Toast all that comes up is a one track audio CD. I've encountered that latter problem before, but usually ejecting the extra audio CD that pops up when you mount it (in OS X) and leaving the actual data CD solves it. But in this case I see no audio CD come up when I mount the thing in Toast.

Everything appears to be there just fine looking at them in OS X (both my disc and the .img file); I'm really stumped as to what might be wrong. I even went and installed Basilisk II running 7.5.3 but it seems to produce the exact same problems. I also seem to have the same problems getting things mounted in my Sheepshaver OS 9 setup (though that wouldn't run it even if it did work). I'm running 10.5.8 (and can of course provide whatever other info might be helpful).

If anyone could go and download Jump Raven (http://macintoshgarden.org/games/jump-raven) and see if you can't get it working I'd appreciate it. Or if you just have any suggestions or wild guesses for things to try I'd be thankful for that too. Thanks for reading.

Hello Defender.
I've just played around w Jump Raven in SheepShaver and to me it seems to work as expected.
I'm running this on Mac OS 10.7.5 and the OS in SheepShaver is 9.0.4
Without mounting the image in OS X startup SS and go to the Preferences. Add the Jump Raven image as a volume and save the settings. Now shutdown and restart SS in order to make the changes in your Preferences active.
From within SS in OS 9 open the volume Jump Raven on the Desktop. I started a game directly from this window but my guess is you ought to copy one of the folders to you harddisk. The installer complained abot not finding the CD but starting from the volume, as above, worked fine.
My guess is OS7.6/8.6 would be optimal. HTH!

No luck here either with SS and a 10.6.8 host.
Though SS is set to 256 colors, the game complains about not being able to set to 256 colors. Sad
Mounting the img seems to work fine with http://macintoshgarden.org/apps/virtual-dvd-romcd-utility after copying it to a SS volume.

INSTALLATION INSTRUCTIONS

You can run Jump Raven™ right off the CD ROM, but the high scores file cannot be saved, and the application will not use extra RAM to improve performance. Jump Raven™ runs faster if part of the product has been copied to your hard disk. We have provided three folders that should be used to transfer Jump Raven™ to your hard disk. The "JR Large Install" folder takes up 30.8 MB and should be used if you have plenty of hard disk space or want maximum performance. The "JR Small Install" folder takes up 200 K and should be used if you have a limited amount of hard disk space or if performance is not that important. The "JR Normal Install" folder takes up 8.5 MB and is a compromise between the large and small folders. This should do just fine for most situations.

Edit: Seems to work with BII here.
Copied file to BII HDD and mounted RavenCD as described above and copied JR_Large over too.
BII crashes on game shutdown if not set to 256 colors.
Game sound not working so far with guest SSW 7.5.3.

Edit: Replaced 'xxx 7' by 'SSW 7' - IIGS User Wink

Oh glory of glories it's working! Thank you so much for your replies.

SwedeBear: I'm amazed you got it running is OS 9 at all; I was under the impression that it would only run in up to 8. In any case setting the volume in the Sheepshaver preferences does make it show up, and it will run off the CD using the FAT file. I got the same error about not finding the CD when trying to run it from the instal.

24bit: Copying the .img file over into Sheepshaver while using that Virtual CD program also made it mount successfully. I got the same error about not being set to 256 colors (even when it definitely is), but in this case too it will run from the FAT file.

Only in Basilisk II (using the Virtual CD method) will the game actually run off the instal. But, same as 24bit, there is no sound. It also runs off the FAT file on the disc successfully (with sound), but takes a long time to start up and the actual action parts of the game run too slow to be enjoyable.

---

This is the first time I've ever had to get Sheepshaver to mount the stuff directly; using Toast in OS X (or a physical disc) has always worked for every other game I've tried up until now. Still, all's well that ends well, and I really am thankful for your help. Running it this way is slightly less than perfect, as it seems that high scores will only save when running it off an instal, but the FAT file seems to work fine and run fast enough (in Sheepshaver), which is enough to make me ecstatic. I've been wanting to play this game again for years.

Thanks again!

Good you figured it out finally!
I did not think of trying the fat executable, though its a known fact that SS is the better choice for playing 68k software than BII in some cases.
Did you try the JR_Large folder and the executable replaced with the fat?

No, but that's a great idea. I'll give that a go and see if it keeps scores.

Yes, that seems to work. Thanks for the tip!

Now if only there was a way to watch the cutscenes and listen to the music outside of the game....
