When SheepShaver starts, it has to reserve the memory amount you set in the prefs. Your problem is well known, but not easily fixed ![]() Thanks for your help and I hope you have enough information to go on here hehe. On my own computer I use the included new world ROM just fine with 512mb of RAM using the exact same files I'm using right now. In a last ditch attempt just now I tried out the old world ROM that came with the release and if I set SS to use 128mb of RAM it will now boot up and stay seemingly stable but I would still like to find a way to push forwards and increase the RAM as this doesn't make much sense to me. Either the one from the Redundant Robot site or a toast image of OS9 I have. The only other thing that could be pertinent to all this is that all the time I have been attempting to boot OS 9 from an image. My ROM files are from the release (Mac_OS_ROM) and the newworld86.rom file from Redundant Robots site (I also tried removing the extension from the newworld86 ROM file). setup.exe as per this windows setup guide. My SDL dll was included in the release and my GTK release I got from here. The versions of SS I used were the release and then eventually the Augrelease. PowerPC CPU emulator by Gwenole Beauchesne SheepShaver V2.3 by Christian Bauer and Mar"c" HellwigÄetected CPU features: MMX SSE SSE2 SSE3 SSSE3 Here is a copy of my stderr file after booting into OS 9 and crashing before the desktop with 128mb ram set: I also have cdenable.sys in the right folder to prevent the error message but I know that is unrelated. It could be worth mentioning my friend has got and an Intel dual core CPU however she is running a 32 bit OS. I've also grabbed the Mac OS 9 boot image from the Redundant Robot website and booting with that but it does the same thing to me. I've done a lot of reading through the forums and so far I have tried checking my "Ignore Illegal Memory Accesses" box and starting the emulator but it did nothing. 256mb did the same thing and so did 1024 but 128mb and lower would load up the startup screen and pieces of the bar down the bottom would load up and before it reaches the desktop it just crashes out. I had the memory set to 512mb of RAM so I thought I'd try to lower it. My alternative, currently, is to just use Qemu, but while I do love its improved accuracy compared to SS, I have several issues with it (this is not the place to detail my grievances, so I won't here).I'm currently trying to setup SheepShaver on my friends Windows Vista Home Premium and on my first attempt after setting everything up correctly (or so I thought) I was greeted with the "Cannot map RAM: No Error" message upon trying to start the emulator. My current prefs are shown below:Äisk D:\SheepShaver\macos9.hfv // Drive letter is correct I also tried doing a "reinstall", so to speak, of SheepShaver. SheepShaver RAM: tried at 512 MB and lower, all the way down to 4 MB SheepShaver build: 22 September 2020, 23 December 2020, 1 March 2015 (fallback I tried using an older version, which had been working before also, in the vain hopes that it was an issue with GTK being included with the newer builds). Host RAM: 16 GB, 4.7 GB in use when attempting to run SheepShaver Host CPU: Intel Core i5-7600K (3.8 GHz, not overclocked) I also attempted to uninstall the one program I installed before I had this error, which runs in the background no dice. rebooting my host machine does not fix the problem. I am aware of why this is happening, but unfortunately. Since probably 26 December 2020, every time I try to open SheepShaver, I get the dreaded "Cannot map SheepShaver data area: No error" error. I know, there have been several posts about this, but my situation is different. ![]()
