Thanks for a great report on the issue. The fact that the game is not booting on No$PSX as well is very helpful, but I still need to dive deeper into what's happening to figure out what could be causing this crash.

I'm glad to know that the report is really useful :)

Test with Vagrant Story (E) [SLES-02754] Same result as the German version, the game crashes in avocado, no$psx and xebra, works in ePSXe

I think it is copy protection ie. LibCrypt http://redump.org/disc/548/ http://redump.org/disc/9978/

USA and Japanese version does not have it: http://redump.org/disc/164/ http://redump.org/disc/1639/

As both versions that not work rely on subchannels then most likely bug is in subchannel handling.

Heh I see, good point @Nucleoprotein :)

Test with Yu-Gi-Oh! - Forbidden Memories (E) [SLES-03947] http://redump.org/disc/1053/ as @Nucleoprotein indicates, the game has LibCrypt

This crashes at start, in no$psx it shows konami logo and crashes.
