I was hoping for this to be a full featured review but alas there are a few major issues to prevent wide spread use of this emulatorâ€¦
First you really need access to a Power Macintosh of some kind to use this. Youâ€™ll need a ROM and a version of the OS that isnâ€™t for free on Appleâ€™s site. Right now Iâ€™m using my 7.6.1 CD to run stuff, and it works great. Honestly its way better than the real deal.. Unless you are running something CPU intensiveâ€¦ Like SIMH on MiNT (all 68000 code) on Sheepshaver (PowerPC emulator)â€¦ it can be quirky at times.
However let me say if you do have MacOS 7.6 â€“ 9 youâ€™ll love Sheepshaver. If you feel left out from the PowerPC to Intel transition and feel you need this old clunker around to run some 68000 apps or even PowerPC system 7-9 applications that are not carbon compatible, sheepshaver is freaking AWESOME.
Iâ€™m still running Vista x86_64 on my laptop where I do most of my work, so for me I needed to download Sheepshaver. Now it does mention it can run MacOS 7.5.2 however the copy on appleâ€™s site is a massive disk imageâ€¦ So youâ€™ll need a Mac to extract itâ€¦ Yeah I know. Â I did make an ISO image to help those who need/want it.
I havenâ€™t tried it, however I do know that 7.5.2 did *NOT* work on my 5400. The good news is that the disk images work between MiniVmac & Sheepshaver. This has saved my sanity (perhaps yours as well!) This does mean that you can also use HFVExplorer to move files in/out of Sheepshaver. A word of caution, the SLiRP networking causes my setup to crashâ€¦ I really donâ€™t know if itâ€™s Vista 64, and Iâ€™m not in the mood to test within Virtual PCâ€¦ emulating within an emulator is a recipe for disaster.
Another thing youâ€™ll need is the GTK+ runtime for the gui configurationâ€¦ I found mine by googling the term â€œgtk-2.12.9-win32-2.exeâ€ â€¦ For some reason sourceforge seems to have issues at the moment with its projects unless you know exactly what you are looking for.
That being said I love sheepshaver. I run it full screen at my laptops native resolution (1280×800) and with the sound on, and it FEELS like a Macintosh Laptop. Even my 1.8Ghz laptop feels snappier than the 120Mhz PowerPC.. But from the Sheepshaver site, they do say to expect to run at 1/8th the speed.. So my laptop â€œfeelsâ€ like itâ€™s 225Mhz. A SCREAMER! Of course this would be horrible for people expecting to run photoshop & friends.
There is no doubt about it, Sheepshaver is great for running old games and applications.
A few tips though. Turn off Virtual memory in Sheepshaver. There is no need for it, as itâ€™s far better to allow Sheepshaver to just have more memory.. In this day & age odds are you can easily allow it to have 64 â€“ 256 megabytes. While you are unable to turn off the disk cache, you should tune it down to 64kb. Although the CPU isnâ€™t much faster than many of the Power Macâ€™s, the disk IO of a modern computer far exceeds it. Most computers are actually IO bound, so running older systems with faster IO gives the appearance of them running substantially faster. Itâ€™s only nested emulation that brings it out how slow it is.
I’ve also found that older version of the OS support more software, and run better. Â That is 7.5.3, 7.6, 8.0 and 8.1. Â 8.5, 8.6 and 9.0 have more PowerPC hooks in them, and SheepShaver hooks the 68000 code to do it’s paravirtualization (it doesn’t emulate any hardware), and the more older tied to the 68000 code tend to be more stable.
That being said, running Mathematica, SoftPC, and Photoshop would not be a â€œgood ideaâ€ if you are expecting faster performance. But at the same time, itâ€™s great being able to run old software that youâ€™ve purchased throughout the years.
