Cannot Map SheepShaver Data Area: No Error
Posted: Mon Jan 04, 2021 4:33 am
Hi all,
I know, there have been several posts about this, but my situation is different. 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 am aware of why this is happening, but unfortunately... rebooting my host machine does not fix the problem. I also attempted to uninstall the one program I installed before I had this error, which runs in the background; no dice.
Host OS: Windows 10, build 1909
Host CPU: Intel Core i5-7600K (3.8 GHz, not overclocked)
Host RAM: 16 GB, 4.7 GB in use when attempting to run SheepShaver
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).
SheepShaver RAM: tried at 512 MB and lower, all the way down to 4 MB
I also tried doing a "reinstall", so to speak, of SheepShaver. Still no dice. My current prefs are shown below:
disk D:\SheepShaver\macos9.hfv // Drive letter is correct
extfs
screen win/800/600
windowmodes 3
screenmodes 63
seriala COM1
serialb COM2

etherpermanentaddress true
ethermulticastmode 0

ftp_port_list 21
portfile0 C:\B2TEMP0.OUT
portfile1 C:\B2TEMP1.OUT
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). Is there any other solution that I'm missing?
