Other 2.1 Legal/Disclaimers 2.2 Thanks 2.3 History 2.4 Contact 0.2 About this Guide ==================== In this guide, I hope to explain what data is stored at different locations in the 7th Saga ROM. Such information would be helpful to anyone wondering about obscure game details, looking for cheats, or writing hacks. Although, why anyone would want to write a hack for this game in 2005, I don't know. And, currently, there isn't enough information here for much besides changing statistics or overwriting dialog. Maybe one day, there will be lots more stuff. But, for trivia freaks and cheaters, what's here might be helpful. Because this is a specific guide, I will not explain game concepts in much depth, such as the apprentice system, the idea that the apprentices get stronger as you do, etc. You could easily infer this from a couple of the tables, but I won't go out of my way to make it plain. To use the guide effectively, you should have some familiarity with hexadecimal (base 16). I won't try to describe it here. You should ask a math teacher or use a search engine if you need help with it. For the stuff in here now, you don't need to know anything at all about SNES assembly. I don't, and I wrote it. All the information here was taken from one ROM image of The 7th Saga. If you have an image taken from a different dump, the tables might not match at all. If you have an image of Elnard, I don't know if anything will match. Is there something fundamental I don't seem to know about ROMs, headers, assembly, or anything else, by which ignorance I'm making mistakes and/or being a fool? Then please, educate me. 0.3 Notes about Offsets, Byte Order, and Notation ================================================= All offsets listed in this guide are ROM offsets, meaning that offset 0x000000 is the start of the ROM. This sounds very obvious, but it bears mentioning because the ROM file that you're probably looking at, you naughty intellectual property thief, you, may have a 512 byte header on the front of it, in which case file offsets are 0x200 higher than ROM offsets. For example, if you're looking at the ROM file, and if you think that offset 0x001000 should have the byte value 0x76, you need to look at 0x001200 instead. Just remember, if the data makes no sense, check at +0x200 before you give up. You might find a utility to remove the header, if you like. The game stores numerical data in 1, 2, and 3 byte sizes with the lowest byte first. This means that the hex strings 01, 0100, and 010000 would all represent the same number, 1. Whenever I write a hex value representing a number in this guide, the highest byte will come first, and the value will have the prefix "0x". Hex strings taken directly from the ROM will have no prefix. So, the decimal number 2500 will be written as either 0x09C4 or 0x0009C4, and it will appear in the ROM as either C409 or C40900. Easy, isn't it? 1. ROM Data =========== 1.1 Format ========== A table refers to any section of the ROM with a set of regular, repeating features. Each repetition of certain features constitutes an entry, and the entries taken together make up the table. Each table description will proceed about like this: - Size: <# of entries>x Entry format: The names/apprentices section is not strictly necessary. Names are found using a supplied offset, but jumping to the offset, adding the file header length, and decoding the alphabet repeatedly can get tiresome. In the case of apprentice data, the data -always- occurs in the same order, but it is included in each table for convenience (or in case some tables actually do proceed in different order). A name value of (empty) just means that there is no name string. The rest of the entry may or may not contain interesting data. Explanations will refer to the literal data in the sample entry. I think this is easier to follow than, say, using placeholders like "xxxx yyyy zz wwwwwwww" to indicate different byte groupings. Especially when cross-referencing with a hex editor. 1.2 Table Descriptions ====================== 0x004DF2-0x0058DE Data Table Pointer Table ------------------------------------------ This table contains a large number of pointers to elements in other tables spanning 0x00623F-0x008A17, i.e. Character Statistics through Apprentice Equipment Data. This table was probably created to simplify changes to game data during development and testing. Size: 932x3 bytes Entry format: xxxxxx xxxxxx: ROM address. Below are the locations of addresses pointing at the different tables. Note that most of these address tables are larger than the actual data tables and contain many identical pointers to empty records. 0x004DF2-0x004E09: (8) Character Statistics 0x004E0A-0x004E21: (8) Spell Lists (list portion) 0x004E22-0x004E39: (8) Spell Lists (levels portion) 0x004F3A-0x005065: (99) Item Data 0x005066-0x0050FF: (51) Weapon Data 0x005100-0x005239: (104) Armor Data 0x00523A-0x0053FE: (150) Spell Data 0x0053FF-0x00570A: (259) Monster Data 0x00570B-0x0058AE: (139) Shop Data 0x0058AF-0x0058C6: (8) Apprentice Interaction Data 0x0058C7-0x0058DE: (8) Apprentice Equipment Data 0x00623F-0x0062BC Character Statistics -------------------------------------- This table determines characters' statistics at the beginning of the game and their gains at each level up. Level gains do not change during the course of the game, but there is a variance of +/- 1 point to each statistic at each level up.

All I know is that there are offsets here referring to city names. The rest is a complete mystery.

These odds always sum to 100, except for Kamil's speeches to Esuna which sum to 110 (bug?).

Size: 44x7 bytes Names: Kamil Olvan Esuna Wilme Lux Valsu Lejes Entry Format: 02 6697B5 06 6798B6 ... 26 719EBD FF 719EBD xx: Level at which following items are acquired xxxxxx: Item codes for Weapon/Armor/Other 0x008A18-0x008B17 Item Drop Sets -------------------------------- This table controls what items an enemy may drop. Each entry has 16 bytes, presumably with a 1/16 chance to pick each byte. If the byte is nonzero, you should get an item. This table may have more than 16 lines. Most of it is blank. Size: 16x16 bytes (?) Entry Format: 47 47 00 00 00 00 00 00 00 00 00 00 00 00 00 00 xx: An item code. Reminder: 0x00-0x63 are items. 0x64-0x96 are weapons. 0x97-0xFF are armors/others. 0x008CC8-0x008DBA Experience Table ---------------------------------- This table contains the experience needed to reach each level above 1. There is a value 0x000000 right before what I marked as the start of the table, but byte alignment suggests that maybe that 0x000000 belongs to something else. Not a good argument? At least I told you. Note: The value here that corresponds to level 81 is unattainable because the game won't store experience amounts over 0x98967F (9,999,999). Size: 81x3 bytes Entry Format: 8C0000 8C0000: A simple 24 bit integer. Entries appear in increasing order, starting with the experience needed to reach level 2. 0x060000-0x06FDDF Text Segment 1 -------------------------------- This rather large section holds most of the game text. It contains all NPC dialog excluding apprentices. A couple of Kamil's speeches are at the top of the segment. It does not use ASCII nor any other common character mapping. Included here is a character table with which a motivated reader may translate the text bytes into English. To get the byte value for a character, add the row and column heading values. | 0x0| 0x1| 0x2| 0x3| 0x4| 0x5| 0x6| 0x7 ----+----+----+----+----+----+----+----+---- 0x00| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 0x08| 8 | 9 | | | | _ | | 0x10| | | | | | | | 0x18| | | | | | | | 0x20| A | B | C | D | E | F | G | H 0x28| I | J | K | L | M | N | O | P 0x30| Q | R | S | T | U | V | W | X 0x38| Y | Z | a | b | c | d | e | f 0x40| g | h | i | j | k | l | m | n 0x48| o | p | q | r | s | t | u | v 0x50| w | x | y | z | | | ? | 1 0x58| 2 | 3 | : | ; | | | | 0x60| | | | | | | ' | " 0x68| - | , | . | HT | SB | CR | MK | HA 0x70| AX | SW | KN | ST | AR | SH | CK | 0x78| | | AM | | | RD | ML | RB 0x80| | | | | | ! | | 0x88|(MC)| | |(IT)|(GD)| | | 0x90| | | | | | | | 0x98| | | | | | | | 0xA0| | | | | | | | 0xA8| | | | | | | | 0xB0| | | | | | | | 0xB8| | | | | | | | 0xC0| | | | | | | | 0xC8| | __ | er | ar | an | be | re | de 0xD0| me | is | if_| ll | se | es | n't|you_ 0xD8| the|The_| it_| It_| to_| We_| we | ty 0xE0|I'm_|have| ble| do | my | oo | st | ed 0xE8| on | fa | y_ | d_ | n_ | wh | in |_ 0xF0| | | | | | | |

That includes Search results, name tables, menu text, a debug interface, etc. It has the same format as Text Segment 1. 2.
