from devkitPro today are libgba and libnds libraries updates, which brings more compatibility between the two and making coding for both platform easier. Macros from libgba have now been added to libnds and changes (most apparent of which are in the interrupt system) have been implemented on libgba. The old functions on the libgba have been replaced with the naming scheme from libnds:

* InitInterrupt replaced with irqInit
* SetInterrupt replaced with irqSet
* EnableInterrupt replaced with irqEnable
* DisableInterrupt replaced with irqDisable

Other new things for libgba are the change from IE_ to IRQ_ on all interrupt masks and input functions (ScanKeys KeysHeld KeysDown KeysUp and KeysDownRepeat) being changed to the same scheme as libnds where initial letters start with a lower case. To know more about the library changes, just browse the online documents for the new updates.
