| byte GetNewgrfCurrencyIdConverted | ( | byte | 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 |
