DeSmuME SVN Changelog:
r4149
Cocoa Port:
- Although the Cocoa port looks very similar to the last update, there have been a lot of changes under the hood! Lots of code has moved around, lots of refactoring has been done, and lots of new code was copied from the upcoming Cocoa code base. Due to this, there have been a few collateral improvements as a result.
- Convert main.mm back to a plain Obj-C file, and remove all code from it. It has now been reverted back to its original empty form.
- Move all app related stuff to appDelegate_legacy.mm/h.
- Move all emulation window related stuff to emuWindowDelegate_legacy.mm/h.
- Because we're now using xibs, translations have been reworked. The English xib is the base xib, and translations now use .strings files to make modified copies of the English xib at compile time.
- Add user interface icons.
- Make the Custom Speed Limit Window panel more functional and look nicer.
- Add new Tools > Show Support Folder in Finder menu option, which opens DeSmuME's Application Support folder. This exists as a convenience for Lion users.
- Remove the View > Constrain Proportions menu option. Now, DeSmuME behaves as if this option is always enabled.
- Combine Emulation > Execute and Emulation > Pause into a single menu item.
- Status text now gives more user feedback.
- Add a sound volume slider to the emulation window.
- Remove the Sound menu.
- In the main emulation window, you can now click close to unload ROMs and quit the application.
- Add ability to save screenshots in JPEG 2000 format.
- Add ability to copy a screenshot to the clipboard using Edit > Copy.
- BUG #3394244: Fix bug where touch coordinates did not map correctly on rotated screens.
