Yeah, anybody with a list of things that don't work yet?

I'm thrilled by this development but kinda busy before Christmas, I hardly get to follow the posts on here and the Garden. What's the status quo? Sound? Video? Ethernet ?

Oh, and Jatoba booted so many Classic OSes on his mini, ha actually got sound to work on 9.2.2! :D it's not perfect, but sound on Mac OS's been a no-can-do forever on any of the G4 minis! 8) JT, you're awesome, man! Please image that specific system folder so it can be replicated easily by others and that key secret sauce is not lost! ;)

Oh, no no, that was for "System Sounds": sound itself always worked on the mini (via a USB audio adapter), but what never worked, and now does, is:

- Changing the volume on the Control Strip (or even otherwise in the System);

- Having System Sounds play when they should, meaning "notification" sounds like ChuToy, Indigo, Sosumi, Beep etc.. While it is still not playing when a normal system alert window pops up, it is now playing for every other situation, such as when you try to click outside the range of an alert window without closing or dealing with the alert first, or clicking outside a file select prompt window, as well as all other situations an alert / system sound should play.

I also didn't try to see if the internal speaker of the mini now works. I don't think it does, but I will check later today just to be sure.

On Mac OS versions from before what a Mac could normally boot, until Rairii's "super" ROMs were released, the following don't work: sound, ethernet, GPU acceleration.

Some other occasional misc. issues also exist, for example:

- Unless you are using one of the latest versions of the System Profiler, the whole OS will hard freeze / crash when you try to open it;

- Pressing Cmd + I for "Get Info" doesn't do anything in some OS versions (works fine in e.g. at least System 7.5.5), but selecting "Get Info" from the Apple menus at the top works just fine for all tested OSes;

- In some versions of Mac OS, you need to move the stock "Mouse" Control Panel out of the Control Panels folder so that the system will succeed booting with all Extensions (seems to be required for System 7.5 ~ 7.5.3, but not 7.5.5, nor 7.0 ~ 7.1.2P, and I think also later OSes);

- Almost every program seems to run as it should based on their respective Mac OS version compatibilities, but there is a few exceptions to that (I think the Puzzle game embedded with System 7.5.x hangs when you start a new game, requiring a Force Quit, but the one embedded with System 7.1.x, which is a bit different of a game, works perfectly).

Rairii, the author of the "super" ROMs as I call them, still intends to get back to audio if nothing else, although right now he's busy trying to see if he can get System 6 to work. (!) His ultimate goal and main motivation and drive is to get Mac OS to boot also on the Nintendo GameCube, Nintendo Wii and Nintendo Wii U, which all use G3-derived CPUs.

About GPU acceleration, I think it is likely just an issue with any of the OSes just lacking the appropriate GPU drivers, although that's just my speculation.
