Thanks! The fullscreen-with-bars mode (pressing ctrl-F twice) does improves usability, since there's less space outside the emulated display area for the cursor to end up in. And in fullscreen, accidentally clicking outside the display area doesn't bring some other app to the front.

If full ...

DingusPPC does have a full screen mode. I suppose moving the mouse out of the window area in that case will be more difficult.
Press Control-F. It cycles between window mode, fullscreen integer scale mode, fullscreen with BARs, fullscreen with no BARs.
You can increase or decrease zoom with Control ...

It's that I'm using Screen Sharing (i.e. VNC) to drive the host machine which runs DPPC, and it apparently does not move the mouse cursor in the same way that the physical trackpad on the host machine does.

I think I remember running into this problem when I was using Screen Sharing to run ...

All 68K and Old World PPC Mac ROMs are on github https://github.com/joevt/MacROMan

The repository includes Mac OS ROM files but DingusPPC doesn't have code to handle them and doesn't emulate a machine that can use them. DingusPPC does have code to identify their uncompressed 4 MiB versions which ...

I haven't seen your video yet. Need permission or something.

Sorry about that. Permissions should be fixed now.

The video clearly shows the problem. What's supposed to happen is that the mouse should not be able to leave the boundaries of the window while it is grabbed. If the mouse is ...

I usually use Xcode to build but it shouldn't matter.

Create a separate build folder for Xcode. Then use cmake to create an Xcode project.

Host OS is Monterey (macOS 10.12) at the moment, but same issue occurs in Sequoia (macOS 15). The host cursor does disappear when ctrl-G is pressed, but the problem is that the host cursor position is not always within the emulator window. If I move the mouse up so the guest cursor appears to be ...

You can see some floating point issues if you run the Graphing Calculator demo in Mac OS 9.

What host OS are you having mouse issues with? DingusPPC uses SDL2 to capture the mouse when you press Control-G. The host mouse cursor should disappear during this time.

DingusPPC doesn't have networking ...

SheepShaver can send modem commands but nothing exists to send the expected response.

You're asking for an emulated modem to appear on the emulated serial port.

There exists code for software modems on GitHub. I don't know if any will do 57.6K or whatever. What baud did you want to get? Or do you just want to do the DTMF dialling?

macOS has DTMF sounds in /System/Library/Components/CoreAudio.component/Contents/SharedSupport/SystemSounds/telephony/

Here's a thread that discusses 2D/3D acceleration for PocketShaver which is a fork of SheepShaver for iOS:
viewtopic.php?t=12683

So you're saying emulators should implement 2D acceleration by implementing 2D acceleration?

That is the plan. SheepShaver has some 2D acceleration. Some 2D acceleration for a couple ATI graphics cards has been implemented in DingusPPC.

An ndrv for the cirrus logic graphics card exists in the ...

Your utmconfigs README.md probably needs an update

For 9.0.4 installs you need to make sure your copy of the cd contain Mac OS Rom version 5.6 or above. 9.0.4 for e.g., the G4 Cube will work. You can find it on the macintoshgarden site.


Is there a link for the Mac OS ROM 5.6? I tried some G4 Install and Restore CDs from the Macintosh Garden but ...

Question is, how did your old files loose their file type/creator codes?

Files stored uncompressed on modern Mac OS X should still contain their Finder Info (file creator and type, Finder flags/attributes, etc.) and resource forks.
Use the GetFileInfo command to check.

I tried fullscreen with DingusPPC on macOS. It seems to work as expected. The guest display window takes over the host display that the window is located on while the other host displays remain usable but only if the "Displays have different Spaces" option is enabled in System Preferences. Otherwise ...

Is the expected behaviour when switching to full screen mode that the chosen display is the same display that the window was located?

Out of curiosity - purely for my own education - how did you identify the block size of this iso?

Notice that the disk image size is a multiple of 2352:

bc <<< "scale=10;$(stat -f '%z' "$theiso") / 2352"


298611.0000000000


Look at the first handful of blocks.

dd if="$theiso" count=4 ...

A command to convert 2352 byte blocks to 2048 byte blocks:

The disk appears to have block size 2352.
I suppose you could use a utility or script to convert this to 2048 byte blocks.

DingusPPC emulator can use CD images that have 2352 byte blocks. Try it at Infinite Mac. Select Beige G3, Mac OS 8.5.1, or similar.

DiskMaster has a "originals" button that ...

DingusPPC requires hard disk images to have partition maps.
Infinite Mac and my fork of DingusPPC have code to allow SCSI hard disk devices to use disk images that don't have a partition map.

For using the Mac OS X 10.4.11 partition of my MacPro3,1, I created a VirtualBox VM (on macOS Monterey) and made the following changes which are documented elsewhere:


# First, create the disk:
VBoxManage convertfromraw "/Volumes/FreeBig/DiskImages/Tiger.dmg" "/Volumes/FreeBig/DiskImages/Tiger ...

I added code to DingusPPC emulator to check all the keys being pressed during startup and post key down events for all of them (modifier keys first). It has to be early enough for the keys to register, but not too early that the guest boot code forgets them. I don't know exactly what the best time ...

The main problem is now I do not have any sound! Cannot even play the system alerts. I start mame with the -verbose option so I can see that my hardware is being identified correctly.
