Vintage Jaguar: Just Enough OS X for Classic!

Very very interesting. I've found classic gaming in tiger to be acceptable to average. I've got a 1.33ghz PB G4. Everymac says minimum pre installed OS is 10.3.3. As stated above this Jaguar really only effects a small number of machines but great work anyway. I've always tried to tweak tiger classic to fix stuttering in games. I noticed my version of diablo 1 started stuttering out of the blue and became really laggy. Was fine beforehand.

Jaguar (v10.2.8) will boot on it nonetheless. Just give it a try. :) Jaguar's Classic is different to Panther's and Tiger's.

Can confirm, I got Jag working on the 1.33 PB G4. Worked just fine! I think I couldn't get airport extreme working, but that was about it – more tinkering may have fixed that (Jag does have airport extreme drivers from the Rev 1 PMG5).

Oh and btw @Hoddy I was using my Powerbook G4 to play Diablo 2. It was buttery smooth in Jaguar! I guess Diablo 1 should be the same.

Wanted to try it on iBook G4, but looks like link in firs post is dead. Any way to re-upload it? And is there any page where i can read about development? Thx!
 
I’ve downloaded the file. But look like I don’t understand the process. I though it is an OS image adopted for unsupported PPC macs and with everting cut off except the classics. And it all comes with installer. And I was just saw files and folders. What I’m supposed to to here? Sorry, and thanks :)
 
It's a Disk Image. You restore it to a (preferrably empty) volume and boot from the restored volume, much like how installing Sorbet Leopard works, sans the jank.

Just tried Vintage Jaguar dmg as well as original Jaguar 10.2.8 DVD on 2nd partition (iMac DVD). Both install, but both suffer from the same issue and that is: no sound on A1095 Powerbook G4 model.

Did anyone solve no sound issue in Jaguar? Can you copy some file? I'm new to Mac world. Can you fix it with Mac OS ROM replacement?

Dark Forces PPC game has very big tearing on all Mac OS X with Classic Env and even the modded Mac9Lives for G4 does not work on A1095. I'm wondering what is A1095 for. It is not for retrogaming and for Sierra with internet it is slow. Maybe only MorphOs. I read whole internet in one week :-D
 
I know it is a known issue, but nobody fixed it? I read about it on multiple places. I have zero Mac experience, but I have Linux experience and I am software developer. If you could point me just at the right direction, I could test it and share the result or share the solution.

1) Drop kext - where to learn about what is kext for sound? I have Jaguar/Panther/Tiger multiboot already, so that is pretty fast to do.
2) Where can I learn about correcting kext for sound? I run out of imagination for google search phrases.

The only issue someone shared is for the modified native OS9 image and the no sound issue was solved by modified Mac OS ROM here: http://macos9lives.com/smforum/index.php/topic,4361.msg48604.html#msg48604

Thank you
 
Ah, so kext means kernel extension. Same as in Unix / Linux. Got it. And it is located in /System/Library/Extensions. I tried briefly copying AppleInternalAudio.kext from 10.4 Tiger, but that got some signature popup in 10.2. Even I click Fix & Use, it did not help.

But I found there is FWAudio and USBAudio kext. So I plugged in the cheapest 5 Eur USB to headphone adapter by Trust and it works! https://d7qztf2ityad6.cloudfront.net/20378/20378_pictures_product_top_2.png?f=RM1920,800

Here's a mini dev bloglet and the reason why things have been a bit quiet.

Remember when I said that I felt the Charlessoft BootCD base was a welcome compromise? As it turns out, while it was great for being small, it was also shockingly fragile, and making any realistic change to the base broke the entire system. I tried to add a user that wasn't root and everything fell apart. I'm pretty sure it was because the login UI was stripped, but that's kinda crazy.

So, we go back to slimming down base Jag ourselves. At this point, I've moved the Vintage Jag development stuff off of the Companion's disk and onto its own dedicated disk. Didn't feel like dealing with partition sizing shenanigans on the same drive as my main OS. This was fine, of course; I still had the Companion's original drive from before I threw an SSD at it haphazardly. Put triple Jags on it: One as a regular Jag, one for Vintage Jag development, and the last for staging.

I kinda wish I could have both drives installed so I didn't have to disassemble the Companion every time I wanted to switch. It's what it's. Maybe I'll get myself a FireWire enclosure. Or use the Twelve as a really flat external drive. It's a shame I can't sac the optical drive for a second bay. Or maybe I can and I just don't know how.

Anyway, the short of it is that I'm rebooting Vintage Jag development. Expect R2 very soon. Not gonna give a hard date though, for reasons.

Stay tuned.

Vintage Jaguar has the following system requirements:​
- A Power Mac, PowerBook, iMac, or iBook capable of running OS X Jaguar, either natively or with patches
- At least 750MB of storage

There are some quirks that come with Vintage Jaguar, listed in this spoiler box:
- SystemUIServer crashes on startup. This doesn't affect the OS, but your menu extras are gone. Shouldn't matter too much though; after all, you did come here for Classic. This will be fixed in a future revision, though.
- That said, with the menu extras being gone, AirPort needs to be configured in System Preferences, which has been left in due to some Control Panels not working in Classic.

You may download a disk image of Vintage Jaguar from the below link:
https://drive.google.com/file/d/1pAnf-ObQGJKUg7SFHPs_TFEkPrPmdP3D/view?usp=sharing Vintage Jaguar.dmg (258.4 MiB DMG file)
Click to expand...
A few questions for the OP/other people that know the answer:

-Is the DMG file an installer, or a bootable image that I can restore to my extra drive partition in Disk Utility?

-I will most likely be running this on my MDD (512mb RAM) The requirement for this is 750mb, but the RAM requirement on lowendmac.com for the official Jaguar os is 128mb. How come its so much higher?


And now that I look back at OP's post, I see that I might have totally misunderstood the system requirements and you might have been talking about hard drive space has to be at least 750mb. If that is what you mean, I'll do 80gb for good measure :)

Correct. It's a drop-in disk image, and 750MB is a storage requirement, not a ram requirement.

R2 may or may not be installer media, depending on if I can get that to work. Maybe I'll see how old hackintosh distros did it and go from there.

Good! I have plenty of hard drive space.
 
I know its in beta but after playing a game in classic, my screen resolution is stuck at 640x480 (stretched) and I can't change it because the preference pane for displays won't load. Is there any way OP can fix this, or is there something I can do on my own to fix it?
 
I'll leave this in known issues, but you should be able to use the Monitors control panel to adjust it.
