Some games' pointers aren't found properly

[turboboy215]

There seems to some issues with detecting pointers in certain games. Three ROMs that won't extract properly that I have tried include "Trollz - Hair Affair! (E)" and "Konami Collectors Series - Arcade Classics (E) (M5), and "Rocket Power - Dream Scheme (U) [!].gba" All of these games are confirmed to use MusyX. When I load the Konami Collectors Series ROM, it finds three pointers, none of which are the correct location, and as such, are missing many samples and have no sequences. With the "Trollz" and "Rocket Power" games, it fails to find any pointers whatsoever. It also may be a good idea to add an option to manually specify the pointer locations as a hex address.
