It's interesting how much difference it makes for a SCSI emulator to use a file on the SD card instead of the whole SD card. SCSI2SD was basically impossible to use unless you already had a working boot disk or a second vintage Mac you could use to format the SCSI2SD and install a System, or...

You could also search for the letters "BD" (0x4244) appearing on a 512-byte boundary near the beginning of the image. That's the beginning of the actual HFS partition and everything else is just noise. If you delete everything before "BD" then you'll have an HFS image that will work in Mini...

It should work with any CD-ROM image, but you may not be able to boot from the image. Very little has actually changed involving the HD20-type disk emulation - it's only that your "hard disk" may now be a specific range of bytes within an image file, instead of the whole image file. Floppy Emu...

Well, I've decided not to pursue the explode disk / export files feature. The straw that broke the camel's back was the discovery that my FAT code only supports creation of files with 8.3 filenames, and the code can't easily be replaced wholesale, so I spent a couple of hours reading about FAT...

Sorry, the correct link for the firmware is https://www.bigmessowires.com/emu/femu-231209M.zip It's too late for me to edit the post now. Mods please help?

If you have a Mac and a BMOW Floppy Emu disk emulator, here's a new firmware https://www.bigmessowires.com/emu/femu-231209M.zip that adds some features I've been discussing in 68kMLA threads. Please give it a try and let me know how it works for you. Even a basic report of "it works fine, I have...

(y) I like the idea of using a special floppy disk image for exporting files, instead of an "explode" feature that can operate on any arbitrary disk image. I think that'll be clearer and easier for the user, and will simplify some things for me too since I can rely on the fact that it's a...

Yes, it currently supports sit, hqx, bin, cpt, and txt files. Other types could be added fairly easily.

Rather than using the address space as a general RAM expansion, with the software difficulties that would involve, how about using it for a RAM disk or ROM disk?

The new Floppy Emu feature is finished and working well to wrap StuffIt, HQX, and similar files inside a temporary floppy disk image. From the user's point of view, files like .sit and .hqx can now be used exactly like .dsk and .img disk images. I wish I'd thought of this a long time ago! For...

On a Macintosh SE, the Floppy Emu adds a second (or third!) virtual floppy drive or a virtual HD20-type hard drive. It doesn't need to replace any of the existing drives.

I'm having some trouble understanding how the current versions of MacOS store resources. AppleDouble stores Filename's resources in a separate file named ._Filename, which seems simple enough. Confusingly, it appears that OSX only uses AppleDouble when storing files on a non-Mac filesystem...

Can you use a backup utility program, instead of dragging and dropping the files? Maybe something like http://macintoshgarden.org/apps/hard-disk-backup

My SuperMac ColorCard SE/30 outputs composite sync at 1024x768. Maybe the "RasterOps 1024x768" setting uses separate H and V sync. That wouldn't explain why it freezes your computer, though.

I see your tiny Smith Corona display, and raise you my KIM-1 :p (not actually mine)

Hey, it works! This VGA adapter quest started several months ago when my Mac IIci wouldn't display a picture on my ViewSonic VG900b, and I stubbornly refused to simply use a different monitor. Here's the Mac Sync-inator running on that same IIci and VG900b, looking good! The picture is stable...

Yes, a tool like CiderPress or HFVExplorer will be the best solution for extracting files, and I wouldn't try to replace those tools. This would be more like an in-emulator version of the simplest use case of those tools, to save time and hassle. There are many options for how the extracted HFS...

Yes, but using which version of StuffIt to make the archives? That's the tricky bit. I'll do some experiments as you suggest. I had a flash of inspiration for another related Floppy Emu feature that I think would be great. In short, it's the opposite of the feature I've described thus far...

What are the normal Creator ID and Type ID for common files that might need to be encapsulated in an HFS disk image? I'd like to encode some simple rules to set the creator and type ID based on the filename extension. For StuffIt I think there are several different ones depending on the StuffIt...

If you were feeling super motivated, you could probably patch the PDQ ROM to make it work under later System versions. There's already another thread going about SuperMac Spectrum ROM dumping, and another recent thread about examining and modifying DeclROMs with Hex Fiend, so you're halfway...
