If we could at least make the sort order consistent, one of the two problems would be fixed.

Idea to display which is disc 1 and which is disc 2: iterate on the game list, find duplicates which have different disc numbers (if any), and overlay a small 1/2 digit in the lower-left corner of the GC/Wii icon. Adding "(disc 1)" or "(disc 2)" at the end of the displayed title might be an easier (but less visual) way to do it too.

lower-right* (lower-left would look weird)

The Notes column has that info for Tales of Symphonia, if you stretch dolphin window horizontally and disable the log it will show up since that column gets hidden if there is little space, for other titles like some resident evil games the disk number is on the title.

For what it's worth, Resident Evil 1, 0 and 4 all have specific game banners with "disc1" or disc2" displayed for their game banners.

Can we detect which disc is 2 ? Is it in ticket info or something ?

yes, at offset 6 disc 1 is 0x00, disk 2 is 0x01

I agree. For games like resident evil 4 which had 2 discs. You need it to show both of them in the list

Revision 2cc1a97a66c2 sorts them based on disc number, but there's still no obvious way to tell which is which, if the notes column is hidden.

So what do we want to do with this? http://pastie.org/6028205 adds (Disc 2) to the title of the second discs. Should i just commit that, or do we want something else?
