Try using dosbox 0.62 command 68 is present there as far as I know.

Now I get everytime a crash with
'Midi:Opened device:win32
Fatal signal: Segmentation Fault (SDL Parachute Deployed)'

Not sure if this will work, but try editing the file dosbox.conf (should be in the same directory as the dosbox.exe itself). Find the section named "sdl", and try changing the value of "output=" to one of "surface", "overlay", "opengl", or "openglnb".

I tried all these options and it crashes with each. 😢

Hmm, what I'm getting here with 0.63 is two splash screens with grey background (and accompanying redbook audio), then scene with a castle, then about a second of music and out to the prompt with "aborted." Is that what you're seeing?

IRunning under the normal core it exits with "Exit to error: PIC:Unhandled command 48" (OCW3 reset special mask) which indeed does not appear to be implemented in pic.cpp.

However, as 4A is implemented (reset special mask and read ISR on next read), I simply copied it over (without changing the ISR/IRR bit), and this makes it work. Patch against current CVS attached.

How can I install this patch?

How can I install this patch?

Ah, well, there are three ways to do that...
-grab the latest CVS, apply patch, compile, install. Since you're asking the question, I doubt this is a good route for you
-Hope the DOSBox maintainers decide this is worth including and put it in the main source tree, then grab the latest CVS build (unsupported, may have sharp edges)
-Same as #2, except wait for the next official release

So for now, basically, wait 😀

Ok. Thanks a lot already 😀

Could anybody test the game with the current CVS? It should work, but I do not have the game to test it.

Yep, looks like the new PIC code is doing the trick.

Yes, it works!

It seems that recent changes broke something in this game. I have CVS from 29.4.2005 and graphics in the intro looks fine, but with current CVS the pictures are garbled. The messy graphics is probably only in the intro, everything looks fine later in the game (but I did not play it until the end). I attached two pictures - the game intro in current CVS and the same scene in CVS from 29.4.2005.

Have you tried using various SDL.dll versions to eliminate that as a cause?

Yes, but to no avail.

I checked the cvs for changes in that period.

I would be happy if somebody could figure out which ones are responsible.
I removed all non-relevant code

Could this be related: RoA : Star Trail + Dosbox 0.62, still annoying graphics glitchs

eL_pusher reports problems in the latest CVS. I was able to replicate corrupted palette symptoms.

that problem is older. although it might be related. (as it got worse I recall)
