Emulation
This app works with: SheepShaver, Basilisk II,

Speed Doubler includes three extensions: Speed Emulator (PowerPC only), Speed Access, and Speed Copy. This software combines an enhanced disk cache, better Finder copy utility, and a dynamically recompiling 68K-to-PowerPC emulator, which was faster than both the interpretive emulator that shipped in the original PowerPCs and the dynamically recompiling emulator that Apple shipped in later machines. It was made obsolete as 68K applications became less common and OS code improved in 8.5 & later.

First DL:
The download contains a disk image with the installer for Speed Doubler 8.0.1, Speed Copy 8 Server and RAM Doubler 2.0.2 updater. Also included in a separate folder is the updater for Speed Doubler 8.1.2 and version 8.1.2 of Speed Copy.

Second DL: German floppy image. IMG, StuffIt 5.
Third DL: Same as 2nd DL, DiskDup+, StuffIt 4 for better backward compatibility.
(DiskCopy 4.2 could not manage to read the floppy.)

Did anyone try using the "Speed Emulator" on OS 9.2.2 and see if there were improvements? Though even if there are any, most hardware running 9.2.2 natively would probably be already "too good" for it to even amount to anything worthwhile. But! Even if so, SheepShaver and QEMU could probably benefit from it, if the 68k emulation is indeed superior than even 9.2.2's...

No idea how to measure this, though... Or, perhaps trying to run the 68k version of Hexen on PowerPC might be a good way to measure things, especially when SheepShaver and QEMU don't have GPU acceleration yet (to my knowledge). This may very well be worth testing.

Edit: Some reports online seem to indicate this program outright does not work with OS 9. If confirmed to be true, this ought to be added to the description of this page later.

It's worth noting that this extension is compatible with BasiliskII. It certainly speeds up the emulated OS, though can also cause crashing when running certain types of processes.

I got past the "master disk" message by using Disk Copy to write the image to a floppy disk and then sliding the read-only tab. It installed from there just fine. Great application.

The installer on this disk image says it requires the master disk--does anybody have a way to make this work?
