Ultima: Exodus has space for three seperate player records. Each one is 0x200 bytes long. Within each record, there is room for party-common data, such as party order, ship position, or whether a horse has been bought or not. This allows one to completely change the characters in their party without losing their party stats.

Within each party record, there is room for 20 characters, each distinct. I will cover the party file first.

This is a work in progess. This information is as accurate as I can get it. Until I find my original notes, I am going from a combination of memory and some records I made in Excel.

For the curious, the Roman alphabet begins with character 0x5E. Many of the characters used in the text table are Japanese, which you may have seen if your cartridge got bumped and ended up with corrupt data.


The offsets are from the beginning of the player record.
