Emulator

rachelbryk Did you confirm this? I just tried with Animal Crossing Wii and Kirby Wii - it seems to work fine.

Yes i did. Download the codes, close the isoproperties window, then reopen it, and the first one is gone.

It is somehow related to dolphin's locale usage being broken, à la issue 6789. Not sure if it's a dupe...

Issue repros when system is non-"en-US" locale.

I don't have time to work on a fix at the moment, but a quick search turned up:
http://trac.osgeo.org/proj/ticket/226d
which leads to
http://msdn.microsoft.com/en-us/library/26c0tb7x.aspx
maybe someone could play around and fix this + the shader issue at once (before I get to it :p).

Hm, I'm not sure it should be high priority considering I can't even repro it when I actively try to. Can someone who can repro it just fix it? :/

OK, finally reproduced in a Win8 VM.
rachelbryk what version of windows do you have?
It seems to not happen on my main install (up-to-date 8.1), so I'm curious if it might actually be some Windows issue(?!)

I'll try to see where the error is happening on win8, tho...

As a note, here is the beginning of the html response for xenoblade:

Use Skip travel to Colony 9 Central Plaza to enable
(recommend not to save) while in these levels If you do just re-enable code to get out

Note that "3D80xxxx 618Cxxxx\r" is parsed by "std::istringstream >> std::hex >> " and as such is parsed incorrectly - after "x" is dropped. The record becomes [0x00003D80, 0x00000000].

For the actual issue:
It looks like in GeckoCodeConfig.cpp:SaveGeckoCode, gcode.user_defined == false for the codes which mysteriously go missing. It looks like this field is not set on any of the codes which are downloaded - the other codes just happen to pass the check because there is some garbage nonzero value there. At this point I would guess the relation to locale setting is just by chance.

Indeed, http://pastie.org/9004697 fixes the issue.
What should be done about the downloaded codes which cannot be automatically parsed (comment 11)?

LGTM, looks like this is my fault when I wrote global-user-directory separation between Sys/User :(

Please make a PR and I'll click the merge button (not on my personal laptop atm).

I'd ignore these edge cases with xxxx as "not important enough to care" unless someone wants to take the time to fix it.
