 It's as simple as that:
-Squall makes step on worldmap, game gets Squall position and tests it with section2 containing region, then loops through section1 and tests groundID and regionID to find ESI multiplier, if random number generates battle, then game gets to section4 using ESI determined earlier with Squall step on world map and plays randomly one of the eight encounters (because one ESI/encounterEntry is 8 bytes, where first four are the most common, other 2 medium and last 2 rarest)

-In script data you have 4-bytes opcodes, the first byte is the identifier, and the last two bytes are the parameter (the second by is always 0xFF).
+In script data you have 4-bytes opcodes, the first byte is the identifier, and the last two bytes are the parameter (the second byte is always 0xFF).
 Scripts always start with 0x01 opcode, and finish with 0x16 opcode. There is always one 0x04 opcode inside.
 For now most is unknown, I only understood that 0x2B opcode refer to scene ID in its parameter (you can find UFO, Koyo-K and Lac Obel battles in Section 32).
