Hey Jubadub,

Whatever image host you used to attach the screenshot is no longer working, and the photo of your screen is gone.  Did you set the image to never expire?  Note: I'm not in the UK or any other territory with those silly age verification laws.

It's not loading because the site's HTTPS certificate expired on Dec 18. Hopefully the move to shorter certificates in a few years will force people to automate their cert renewal and make problems like this a thing of the past.

Same here. I've contacted the image hosting sites owner fogWraith (who I run Macintosh Garden with) and he's on it :)
EDIT: Seems to be working now!

Has there been any progress with getting audio working... or compiling the most recent PPC compatible extensions and control panels into versions of 7.x?

I've updated the Mac mini 7.6.1 CD to Test Version 0.2.

You can download the iso from the Macintosh Garden if you want to try it out:
https://macintoshgarden.org/apps/mac-mini-g4-system-7

CD 0.1 had some incorrect icons; the System itself is unchanged from 0.1.
Also now just a 43 MB download.

I tried installing on my mac mini on a partition - have OS9 and OSX already and used the Apple System Restore on the cd in mac os 9 to install on to a spare partition.
OS7.6.1 is seen on the boot menu (when hold down option key at startup) but trying to boot just gives the floppy icon with a "?"

I should say it boots fine from the CD but the disk initializer shows the hard drive as empty and ready to initialize so I assume system 7 cant cope with the more modern partition table?
Guess I'd have to wipe my whole drive to install and it would have to exist on it's own?

I had formatted the spare partition (800mb) to HFS not HFS+ using the terminal in OSX

What do you mean "more modern partition" table? Your disk is formatted with Apple Partition Map, not GPT, correct? GPT is supported on Intel Macs and maybe Power PC Macs after July 2005. I don't have firmware dumps between April and June 2005 to check those. If you have a Mac or firmware version not listed in the "List of Open Firmware versions" at
 https://forums.macrumors.com/threads/question-how-powerful-of-a-graphics-card-will-work-in-a-beige-power-macintosh-g3.2303689/
then I would like a firmware dump to compare.

Just supposition on my part - relatively new to old macs.
Using a PPC mac mini G4 1.25GHz and yes, formatted with APM not GPT
OSX and OS9 partitions in HFS+ and the partition I was trying to get system 7 to run on formatted in HFS+ initially, but when that didnt work, tried HFS

Well you made the right call going to HFS since HFS+ was only introduced with Mac OS 8.1. Also, be sure your HFS partition is bootable and less than 4 GB.

I am not sure why it isnt booting unless it needs to be the only OS on the drive.

The system folder has the system folder icon so I assume it has been correctly 'blessed', and it is recognised as bootable on the boot option screen

The disk initializer does see the HDD as an ATA device when I boot from CD but doesnt see any partitions and doesnt mount any of them on the desktop either.

They all appear fine in system 9.2.2 and OSX

You probably should partition the drive using the System 7 utility, to make sure it creates something it can understand, and most importantly installs the drivers. 

I used it and made two (hfs) ones, installed System 7.6, then booted into Tiger and reformatted the second partition hfs+ and restored tiger on it, so I can dual boot.  It defaults to 7, and I hold down option to get to Tiger.
