System Titles[edit]

<fill this in (manually) later>

Home Menu[edit]

Only one function was updated, the function which loads theme body-data with theme-shuffling enabled. This now does: if(loadedsize > input_max_size)fail. Hence, the latest exploit used by menuhax at the time of this sysupdate release is now fixed.

RomFS was not changed at all.

Internet Browser[edit]

Old and New 3DS Internet Browser were updated. Both browserhax_fright_tx3g(New3DS) and spider28hax(Old3DS) were fixed.

As of "Wed, 24 Feb 16 20:00:01 -0500", updating to this browser version is now required since the server browser-version-check pages for Old3DS were updated. This does not affect New3DS currently.

Socket sysmodule[edit]

Minus changes from an older CTRSDK version(CTRSDK version seems to be the latest now), only one actual SOC-specific function(L_11154c) was updated. The previous version did: <write u8 0x0 to ptr and increase ptr by 1>. The current version removed this so that L_11f9f0() is called with ptr, without writing data to ptr+0/changing ptr.

IR sysmodule[edit]

Exactly two functions were changed. Originally the two functions for reading I2C-IR registers TXLVL and RXLVL just used i2c_ReadRegister8 then returned the output u8. Now each function reads the register, then returns the output value if it's <=0x40. Otherwise, the register is read again. If the output value is <=0x40, the output value is returned, otherwise 0x0 is returned.

With the original IR hardware the value returned by these registers are always 0x0..0x40 according to the datasheet.

This fixed the vuln described here.

JPN-only titles[edit]

Multiple titles for JPN-only were updated. For System Settings and "Nintendo 3DS Camera", only the manual content was updated(the main contentid in the TMD wasn't changed at all). Other titles were updated for JPN-only too, presumably with the same manual-only change.

CHN-only titles[edit]

The amiibo Settings system-applet was added for old 3DS, yet is identical to the Taiwan version.
