It's a bug in the game code. It looks like its supposed to transition to black at the end of a level, then fade back up for the next, but its doing both in parallel. I suspect there's supposed to be a timer running whilst it fades out, before it goes to the next level to the fade back in. I've disab...

I've looked at the game code and can't see any obvious reason for the palette to go black. The palette swap code is all hanging off VSync, so does occur at the correct time...so it's more likely to be a bug in the game or possibly protection kicking in. Whilst investigating, I've back-ported the var...

It's an issue caused by WolfLoad. Instead of allocating the correct amount of memory for the game, it allocates all memory leaving none in the free pool. That causes RMA memory allocations to come from the end of application space, which triggers an abort the next time the User stack is touched by t...

Interestingly, &0001A3DC is *adfs:Dismount :0

I'm not sure why that would trigger an abort.

See if the attached recording file works. I quickly tested I could start a new level, but haven't played beyond that to see if I need to capture more sectors.

If it works for you, I'll add it to the ADFFS 2.84 public beta, which I need to update this week following a few bug fixes.

I suspect my issue is going to be down to the recording file I used. There is no recording file for this game in ADFFS, as it just shows the default eform800 file when you select Wolfenstein which does not image the copy protection. Although I documented the protection in use , I've never created r...

I'll have to dump the game and look through its code to see what it's doing. It certainly sounds like something is going out of sync.

I don't recall if its this game or another, but there was at least one game that stored code in the video memory and switched the palette to black to hide it.

What refresh rate is your screen?

My first thought is its not changing the palette at the correct time during VSync, which is causing the palette to remain black.

Does it exhibit the same problem when HD installed? Instructions will be in !ADFFS.Obey.F1038801 Try the ADFFS script with the original floppy to see if its the script or the floppy images. Drop to Supervisor with the original floppy inserted, then: *ADFBootFloppy F1038801 I've just tried my origina...
