Has anybody taken the time to map the GNPRTB.DAT file? I have started to, but mostly I'm building on other peoples work here... There are 213 entries in this file. Each one is mad up of 11 'sets' of 4 alphanumeric 'couplets' (I'm not sure what the proper terms for these are...). For example, the first entry (starting immediately after the hex header data) is: 01 00 00 00 01 00 00 00 01 00 00 00 64 00 00 00 64 00 00 00 00 64 00 00 00 64 00 00 00 64 00 00 00 00 64 00 00 00 00 64 00 00 00 00 64 00 00 00 00 set1: a counter (01 00 00 00 through D5 00 00 00). set2: unknown, ALWAYS 01 00 00 00. set3: a more complicated counter -- the first couplet seems to be a counter within some kind of subgroup. For the first entry only, it starts at 01, and every group after that starts at 00 and counts up from there (the largest of these subgroups, the last one in the file, goes up to 57 [hex], skipping 3A through 4F in the middle... this is the only one that skips as well). For each of these subgroups, the second couplet in the set seems to identify the group and is the same for each entry in the subgroup (entries here are possibly more counters -- entries are: 00, 02, 06, 08, 0A, 0C, 0E, 10, 12, 14, 18, 1C, and 1E -- basically, counting off even numbers, skipping 1A). The remaining two couplets in these sets are always 00 00. The remaining 8 sets are always the same (for each entry) and have the following effects: set4: unknown set5: alliance on easy difficulty set6: alliance on intermediate difficulty set7: alliance on hard difficulty set8: empire on easy set9: empire on intermediate set10: empire on hard set11: unknown I only know what two of the 213 entries control (thanks to lookiamluke and the Hyperspace Speed Locations thread for this): the first entry (set1 = 01 00 00 00) controls the hyperspace speed of all things not ships (i.e. characters, facilities, etc.) the 60th entry (set1 = 3C 00 00 00) controls the hyperspace speed of Han Solo (and anyone traveling in a group with him) Does anyone else have ideas on the other 211 entries?
