The corresponding entries in trek.exe seem to have no more than 2 valid values: "E9" (energy) or "F6" (food). Any other values that I tested resulted in a crash.
These are the positions:
Code: Select all
position default planet type
0x3E260 E9 desert
0x3E264 E9 gas giant
0x3E268 F6 jungle
0x3E26C F6 oceanic
0x3E270 F6 terran
0x3E274 E9 volcanic
There are no entries for arctic and barren planets, but they have the bonus type "energy" by default.
Note that any bonus values given to arctic planets, barren planets, or gas giants via planboni.bin will automatically be multiplied by 100 in the game. For example, a bonus value of "2" for suah a planet type in planboni.bin will result in an actual 200% bonus.
