|
||
* Sample game: [150226] 結城友奈<E58F8B>勀<EFBFBD><E58B80>ある 体験版
|
||
*
|
||
* No GDI functions are used by this game.
|
||
*
|
||
* Debug method:
|
||
* There are two matched texts.
|
||
* The one having fixed address is used to insert hw breakpoints.
|
||
*
|
||
* I found are two functions addressing the address, both of which seems to be good.
|
||
* The first one is used:
