There's two crashes at the end of the intro one caused by the cdda ending before the video that I pushed a fix for yesterday and one cause by the game overwriting the sound irq vector with zero. If the different avsdrv version fixes the second, that's good news. FWIW though, you can skip the intro by editing the pnauts.bat to remove the /o option on itp.exe. I was running itp directly without /o, I didn't realize what it was for.

Just pushed a change which fixes the avsdrv that I have.

Cool, now even the talking animations work! I can't even get that on real hardware, since the Nw150 has the integrated equivalent of a 118 sound card.

Can you load saved games, though? I get a "stack overflow" error if I try:

(the text below more or less translates to "an illegal interrupt has occurred, interrupt number 01H, please press the reset switch")

0b17c32492a9a656aa97d2ea09bd33142e594ade is an utterly gross hack, and might well be responsible for the "illegal interrupt" error.

It wouldn't be because int 1 is not an irq vector it's the trace interrupt.

If we could get Policenauts in good shape and maybe softlist a translated version that would be one heck of a release highlight smile

Sadly, I don't think there is a translation for the PC-98 version, not even a partial one. I'd imagine it would be quite complex since, unlike the console versions, it doesn't have subtitles for the voiced dialogue (and there's a ton of it).

It's a shame, really, because it's a really interesting release. It's the only version of the game with high-res pixel art instead of cel-based animation, and the only PC-9821 game Konami ever released.

Ahh, too bad. Still, getting it running 100% would be great.

So, more Policenauts strangeness... underclocking the CPU to around 70% gets rid of the sound skipping completely... but that also breaks the intro again because the CDDA track ends too early. Some weird timing issues going on there, especially considering I've seen the game run fine on a much faster CPU on real hardware.

Committed a work around for this that I'm not entirely comfortable with. Policenauts seems to expect the irq to be retriggered immediately if the fifo is still below the irq level when it's cleared. If I do that then Dangel blows up when the voices start so the fix is an attempt at a compromise. I hope there won't be but wouldn't be particularly surprised if there are regressions elsewhere.
