When playing the ending of Mask of Eternity, after Lucreto is sucked into the vortex and the game pulls back to the stone wall (I have it where I see what Connor sees) and the game crashes. I know all that's left is the video of the ending...but is there a way to get this to play, or could something be wrong with my install? The ending played fine until I had to reinstall after reinstalling windows.

If seeing my save would help, just ask and I can upload it, I have a save from after the fifth piece of the mask has been laid down

You could try <span class="bold">nicode's</span> re-encoded videos.

This is old and unlikely to help you, but maybe someone else will benefit. All credit goes to user ARABLIZZARD2413 for this solution. I am just trying to simplify or make it more accessible to the non-techy people out there.

The KQ8 videos/cinematics use a video codec that was bundled with old versions of Windows, but has since been disabled by default due to possible security issues.

To fix this, you need to use the Windows command prompt. These steps may vary depending on what version of windows you use. All of my instructions are using Windows 10.

Step 1.
Locate the file called "ir50_32.dll" on your computer. This will be located in a Windows system folder. On Windows 10, it's located in "C:\Windows\SysWOW64" ... if you can't find it, try using the built-in Windows search features to find this file. Note down the full path to this directory (in this case, it's just C:\Windows\SysWOW64)

Step 2.
Open the "Administrator" Command Prompt. This is different from the normal command prompt as it has elevated privileges. To access this in Windows 10, press Winkey+X, then click on "Command Prompt (Admin)". You'll then see a black screen that you can type in (looks like the old MS-DOS prompt, if you're old enough to remember that).

Step 3.
Using the command prompt, navigate to the directory that you found above. The command to change directories is "cd", so in the example directory above (Windows 10), you'd type "cd C:\Windows\SysWOW64" to move to that directory.

Step 4.
Type "regsvr32 ir50_32.dll" and press enter. You should get a popup in Windows notifying you of success.

The codec needed by King's Quest 8 is now enabled on your machine. You should be able to watch the intro cinematic & others without any errors. (You may need to repeat the steps above if you restart your machine).

All I had to do was set compatibility to Windows XP. Using Win 10 64 bit. Can play videos no prob

Not the GOG setups that I have seen in the past.
Download kqmoefix.zip at http://svn.nicode.net/kqmoefix/bin/ extract the kq8fix.exe (archive password is "kqmoefix") into the directory where you installed KQ8, run it, enable the shim for the Mask.exe, and make sure 'emulate ./cd/ as CD-ROM' is checked... play KQ8 and report any issues with kqmoefix :-)

Yeah, KQ8 won't work if you don't have a DVD/CD-ROM drive on your computer. I had the same problem as you with a very similar setup. You can emulate a CD-ROM drive using a number of tools (I used Virtual CloneDrive which is free: https://www.redfox.bz/download/SetupVirtualCloneDrive.exe) but Nicode's solution is probably easier and I believe it addresses some other common issues too.

Most noticeably the infamous "TalkComplete" bug (missing game events / cutscene freeze) that has never been fixed by Sierra (they provided saved games as workaround) and the broken saved game loading on Wine - the primary reasons for developing kqmoefix.

ps: And while we are at it... my English isn't that good (other languages are very welcome). The resource files need some proof reading by a native speaker: setup/setup.en-US.rc.

I gave it a try for you, sent some notes in chat.

Many thanks! I finally got a chance to look at this again and got the game running (sans intro). This is the only one of the series I never played so I'm looking forward to it. Thanks for the help! I tried nicode's suggestion and got the game running. Now to see if I can actually play it! Thanks for responding.
