This steam thread might help then.http://steamcommunity.com/app/214770/discussions/0/846960628457513544
As a side note, I'm not sure why you would need to do dotnet winetricks thing for controller support. If the game works with dotnet, then sure, but dotnet just for controller support sounds odd to me.
x360ce in particular is just running an app and configuring the controller and copying its xinput dlls into the game's install folder path.
I used dotnet because that's what the system requirements call for: http://www.x360ce.com/
I got x360ce to work. http://i105.photobucket.com/albums/m234/qwerty_warrior/x360ce_screen.png
I also looked at the WineHQ AppDB for a bit of help. https://appdb.winehq.org/objectManager.php?sClass=version&iId=31736
I used a clean Wine directory with WINEARCH=win32.
I'm guessing you'll need a clean Wine folder to setup x360ce and use the same Wine folder that detected the controller to install Guacamelee.
On a clean Wine folder, you can use winetricks to do this:
$ winetricks dotnet35 dotnet40 vcrun2010
$ winetricks directx9
directx9 has to be installed AFTER the dotnet and vcrun. During the dotnet3 installation (with the message that the install should take 3 minutes on a fast computer), there was a notification that the install finished but Winetricks refused to move forward. I looked at the process table and killed the exe to make it continue.
9659 pts/11 Sl+ 0:00 netframework3.exe
9662 ? Ssl 0:00 C:\windows\system32\explorer.exe /desktop
9668 pts/11 Sl+ 0:13 y:\fff94adfbe21fcf8a67187c73ae673cb\setup.exe
$ kill -9 9668
Then, winetricks resumed and installed the rest. I clicked on reboot when the installer asked, not that the computer would actually reboot. lol.
Then, I used this to execute x360ce.
WINEARCH=win32 WINEPREFIX=/path/to/.local/share/wineprefixes/x360ce wine x360ce

Hope it helps, Judas! Then, the Steam thread has some things specifically on configuring x360ce for Guacamelee (maybe).
Side note: Yikes! I should get the later Wine builds! This is way too old!
Double side note: Installed wine1.8 and it still launches. Anyway, just trying to help Judas.
