Syscall index: 0x0C6B
Function signature: void APP_FINANCE(int, int)
Opens the built-in Finance app.
The meaning of the two parameters is unknown; they are probably the same as, or similar to, the isAppli and OptionNum options of the main function template from the fx-9860G SDK.
Note that even though most built-in apps do not return, the calling code is kept on stack and one can return to it using a ugly hack, for example through timers, setjmp and longjmp. The reason why they don't return is that they expect to use GetKey as an exit point.
