FOREWORD: How to read Arcana's event code

The majority of Arcana's subroutines are through opcodes, which is like reading another assembly language. (See this page's Bank 00 section for command details.) The code uses a set of commands, the animations use a different set of commands, and drawing text to the screen uses a third set. They are very difficult to follow with just a standard tracelog. Predominantly when tracing or breakpointing code, you'll see a lot of the 00/902B command "LDA [$10]". (This is SNES for: read the address stored in the variable $xx10, read the value at that address, and store that value in the accumulator.) After 902B reads an opcode [byte], it goes to a pointer table and calls the code for that command. (For instance if 902B reads a "07", the table tells it to call 00/9527. 9527 reads the next 3 bytes after the 07, then jumps execution there. In other words, it's a subroutine call.)

Since many commands read adjacent data, it is *much* easier to follow along if you can read ahead a few bytes too. So, it is highly recommended to follow along in a hex editor when tracing. Reminder that this is a LoROM game, so something the emulator says is at 01/9260 will be at byte 9260 in your separate hex editor. Something at 02/8000 will be at byte 10000. A tool like Lunar Address can easily convert between PC addresses and SNES LoROM addresses, it's a good idea to double check before digging around in the wrong area. 

Also keep in mind that the SNES is little-endian, so a 3-byte pointer 07/B220 is read in reverse as 20 B2 07.

So here's an example. This is the event handling for the "Look" command that checks for treasure chests. These show the ROM location being read, the bytes being read (the opcode is spaced separately from the parameters for clarity), and a summary of what happens there.
01/9260: 30  FF                     Clear the animation ID
01/9262: 07  20 B2 07               Call subroutine 07/B220, which returns 1 if in a dungeon or 0 if in a town
01/9266: 0B  72 92                  If false/0, jump to 9272 (don't open a treasure chest if in town)
01/9269: 07  16 A8 07  80 00        Call subroutine 07/A816, compare current floor tile to 0080 (treasure chest tile). Return 1 if true.
01/926F: 0C  7D 92                  If true, jump to 927D
01/9272: 07  AC A0 00  BD 8F 08 00  Call subroutine 00/A0AC to display text at 08/8FBD "Nothing here !" (the 00 parameter is used by the text parser)
01/927A: 1A  8A 92                  Jump always to 928A (waits for an A press, then closes the menu)

01/927D: 07  27 A8 07               Call subroutine 07/A827 (looks up and saves the treasure chest contents, and animates the chest opening)
01/9281: 06  1E                     Wait 30 frames (for the chest to finish opening)
01/9283: 07  3D A8 07               Call subroutine 07/A83D (get treasure contents, add money/item/equipment to inventory)(returns 1 if the chest is a trap)
01/9287: 0C  A5 92                  If true (trapped chest), jump to 92A5 to start a random encounter (this is dummied out)
01/928A: 06  01                     Wait 1 frame
01/928C: 07  03 BA 07  00           Call subroutine 07/BA03 (wait for an A press) (the 00 parameter is related to the pause status)
01/9291: 0B  8A 92                  If false (the player hasn't pressed A) loop back to 928A.
01/9294: 06  0A                     Wait 10 frames
01/9297: 07  07 9D 00  74 B6 01     Call subroutine 00/9D07 to read formatted data from 01/B674 (related to closing the text box)
01/929D: 06  01                     Wait 1 frame
01/929F: 16  7B 15  01 00           Set RAM address $157B to 0001 (display the compass again)
01/92A4: 1C                         Return from subroutine (return to wherever the code was when 01/9260 was called)

This example is about standard in length. It's much easier to read this kind of code this way, but it's a laborious process by hand. *Most* opcodes read a set number of bytes, with the exception of subroutines and switch-case statements. So with the habit of seeing a 07 followed by a 3 byte pointer, or 0B followed by a 2 byte pointer, it's much easier to spot where the code is going next.


Now for something different, an example of text opcodes. The breakpoint for these is 00/A7B5 "LDA [$06]", where $06 is the current character or command.
This is from SCRIPT_003, where Rooks meets Ariel. The subroutines are shown to give a sense of how often the game calls the same commands.

0C/F7F8: 05  FF 14                  Wait 14 frames

0C/A2D5: "Yes."

As you can see, while code opcodes called actual ASM, text opcodes only call more text opcodes. But that's a general rundown of what things look like internally.
