The ones you need now are:
libasound2:i386
libc6:i386
libgdk-pixbuf2.0-0:i386
libgtk2.0-0:i386
libx11-6:i386
libxau6:i386
libxcb1:i386
libxcursor1:i386
libxdmcp6:i386
libxext6:i386
libxfixes3:i386
libxpm4:i386
libxxf86dga1:i386
libxxf86vm1:i386
I think that's all of them. If I missed any, you should be able to find them with ldd and apt-file:
Code:
$ apt-file update
...
$ ldd zelda-l
...
libXdmcp.so.6 => /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0xf72ef000)
$ apt-file search libXdmcp.so.6
libxdmcp6: /usr/lib/x86_64-linux-gnu/libXdmcp.so.6
libxdmcp6: /usr/lib/x86_64-linux-gnu/libXdmcp.so.6.0.0
libxdmcp6-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/libXdmcp.so.6.0.0
