From: El Paso, TX
While correlating Japanese ship bmps with the database records in Scenario 1, I realized there were 33 bmps unaccounted for (see list below), and can confirm that all are "as-delivered" files, installed as part of the v1.126a patch. After reviewing the database records in quite a number of other scenarios (mostly those which might be giving the Japanese new classes of ships to work with), I finally found that four of them are used by DaBabes mods (0259, 0260, 0269, & 0270), while two others (0276 & 0314) were modified around the same time, and thus might be used by some scenario.
Which leaves 27 bmps that are of no use whatsoever. In checking the file creation dates, most of the files are from 4/10-11/2009, except:
0055 and 0058 are from 3/22/2002 - perhaps UV leftovers?
0104, 0170, and 0171 are from 4/7/04 - identical "alternate Yamatos", but the art quality is abysmal
0276 and 0314 along with the four DaBabes files are dated after July 2009
Most of the rest seem to be duplicates of other shipsides, so it's unclear why they would be needed. Anyway, there's no real harm, other than they take up a little hard drive space, but it's possible that modders might want to make use of these 27 file slots. Also, if anyone is aware that some of these ARE used by existing scenarios, please say so.
