Virtual Jaguar Linux & CD support

ctirad · August 6th, 2005

Hello,
I sucessfully compiled both 1.0.7 and CVS version of Virtual Jaguar on my Linux box. It can run some games pretty well, but how about Jag CD support ? I know there is some CD related code as well. I tried to load jagcd BIOS, changed cdrom path in sources to /dev/hdc a inserted one of my Jag CDs into drive and set "reset CD" from the menu. The CD bios works correctly, I can see all the flying stars and graphics, but then only "no CD power" logo appears and no CD activity at all.

Here is the log:

In short, JagCD is currently only supported on WIN32 based operatingsystems. I had JagCD working under Linux but unfortinately lost my job and my development data which resided on a laptop

I hope to get started on JagCD support for UN*X based systems ASAP. But first I need to examine the new code from Shamus ( I was "away" for a while ) and found out what happened to my old source backups from 2000 and 2001.

Regards,

Niels Wagenaar

**Shamus** · August 7th, 2005

One thing that is absolutely vital to the proper functioning of the CD BIOS (besides a functional backend

) is to have the DSP enabled. But judging from your description, it sounds like you did. Hm. I guess we'll have to dig into that Linux backend.

Niels: I'll try to catch you on #ngemu when I can.

**Shamus** · August 9th, 2005

I forgot to add that the CD functionality isn't 100% at present but is looking quite good at the moment. And it should get closer to the 100% mark now that I have some good documentation on the CD BIOS.

How good/bad is Jaguar CD emulation in the Windows version?

**Shamus** · November 15th, 2006

Currently there are some bugs in the Jaguar end of the CD code, so while it almost works there's something wrong and I haven't had time yet to look into the problem. I may have some more time to work on the Linux backend so maybe a solution will present itself when that happens.

My comments:

First, thanks for all the work you've done on this emulator...

I'm an avid Jaguar collector (some might say a Jaguar nut!) and while playing games on an actual Jaguar is the best option of course, I do enjoy firing up T2K or Val d'Isere while killing time at my office...

I know the CD functionality is important to many folks, but for me it's an extra, as the majority of released games are on cartridge. Personally, I hope you guys can do a little more tweaking of compatibility for the core system. I don't want to be a whiner or seem ungrateful - honest! - but realistically the compatibility for just the core system is not that high. Sorry! but it's true: I find that only about 1/3 of games run decently; many games don't get past the starting menus, and of those that do, often times they don't run well or they lock up after just a few minutes.

Sorry, I don't mean to be a whiner... I really do appreciate the hard work you've put in on VJ, and I hope we see more soon!
