uint64_t GetMaskOfAllowedCurrencies | ( | ) |
get a mask of the allowed currencies depending on the year

uint8_t GetNewgrfCurrencyIdConverted | ( | uint8_t | grfcurr_id | ) |
Will return the ottd's index correspondence 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 |
