Ultima: Exodus has space for three seperate player records. Each one is 0x600 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. Each character record is 0x40 bytes long, for a grand total of 0x500 bytes. This dovetails nicely within the 0x600 space for the player record. 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 0x8A. 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.
Roman Characters (This game only has upper-case): 0x8A through 0xA4 Period and comma: 0x42 and 0x43 respectively Numbers (standard non-japanese): 0x38 through 0x41
Map summary:
Player record total: 0x600 bytes
The player record is:
Party record: 0x100 bytes
Character records: 0x40 bytes * 20d
The offsets are from the beginning of the player record.
