 Lots of numbers and addresses in the [Tycoon Technical Depot][ttd] are written in hex. The prefix "0x" generally denotes a hex address. The letters used for hex are a superset of those used for decimal, so numbers which look like decimals ("12") can actually refer to a different value than you think (in this case, 0x12 = 1\*16 + 2 = 18). In IDA these are represented as numbers with the letter "h" as a suffix, like "1Ah".

 Note that RCT2 uses a [little endian][le] encoding for integers that span multiple bytes, so the most significant bit is in the 2nd byte of a 16-bit integer.

 Always remember that pointers are unsigned do not try to use them as a signed integer otherwise you may end up at the wrong address.
