Verify if the currency chosen by the user is about to be converted to Euro. | |

byte GetNewgrfCurrencyIdConverted | ( | byte | grfcurr_id | ) |
Will return the ottd's index correspondance to the ttdpatch's id.
If the id is bigger than the array, it is a grf written for ottd, thus returning the same id. Only called from newgrf.cpp
grfcurr_id | currency id coming from newgrf |

void ResetCurrencies | ( | bool | preserve_custom | ) |
Will fill _currency_specs array with default values from origin_currency_specs Called only from newgrf.cpp and settings.cpp.
preserve_custom | will not reset custom currency (the latest one on the list) if ever it is flagged to true. In which case, the total size of the memory to move will be one currency spec less, thus preserving the custom curreny from been overwritten. |
