Konami will be putting Nintendo's 3DS patching system to use through two upcoming patches for New Love Plus.
The first patch will arrive in mid June. In addition to various bug fixes, the patch will make improvements to touch control response, and also add some refinements to the various forms of communication with your girlfriend (e-mail, phone, etc.).
The second patch, due for release between late August and early September, will speed up some controls, fix the ToDo event system, and reform the schedule input screen. This is just a partial list of the planned fixes.
