Term
| Where do you copy the address of your custom interrupt service routine to in GBA memory? |

Term
| Since the GBA CPU is a RISC processor, we can manipulate multiple data items in memory at once. |

Term
| Because of the way parameters are passed to C/C++ non-member functions (NMF) and C++ member functions (MF), those that pass over N parameters should be considered less efficient. What is N? |
|
Definition
| 4. If your function takes more than 4 parameters, you should pass a structure pointer instead |
