Crystal Caves – Progress on the Script Extractor

A cool guy called DDS has sent some info and prompted me to work back on the project, it seems he’s gone so far as to hack the game to use single sprites as letters instead of 4 sprites kanji, which is something extremely important for the translation.

I have updated the Script extractor based on DDS’s findings:

  • Marking back newlines, which I had removed
  • Subroutines
    • 0x8C (jump to)
    • 0xC0 (set flag)
    • 0x88 ~ 0xDO, unidentified
  • Grouping subroutines calls in groups of three bytes

Still figuring out the usage of 00 as a dialog termination sequence. Some times it’s there, some times it’s not. There are also some stranded bytes, probably some subroutines use a single byte or 3 bytes (?)

Also, the byte sequence after the charset is probably data instead of code, may be the dialog options are there (?)

I’m also integrating with Google Translate API to provide a rough translation, mainly to detect the point where the first dialog ends and nonsense starts.

Here’s the output so far:

<dialog id = '16'>

  1. I messed around a bit more to see how hard it’d be to get dialogue options working, and it seems like it wouldn’t be too much trouble. They are located around $14BB0, and are preceded by a byte that acts as a counter. So these can be modified to allow for longer or shorter names, but it doesn’t seem to work 100% of the time (for some reason, I couldn’t change the one for “Jimmy”). I’ll try to figure out why, though it may be easier to just move all of these out to a wider blank space to work with and change how it indexes them. They also seem to be unique to a character. Talking to someone else with “Job” or “Name” has it untranslated.

    Here’s a better version of the first pic from my last post.

    And here’s a zip file with an IPS of what I’ve done so far.

    In your EUC charset for Dialog 16, the values from “誰” onward seem to be set to 20h bytes higher than they should be. So for example, where you have “ぐかが”, it should say “誰かが”. It ended up making the second half of the Japanese text look scrambled.

    The text that follows the “96 97 97” seems to be more sequenced characters, that likely depend on another charset being loaded. Maybe it’s someone else’s dialogue?

    I’m looking into the dialogue system more so that you can continue on the extractor tool. I’ve mostly just been trying to decode the commands in this same speech dialogue, and here’s what I can tell.

    88 = Blank out RAM?

    8C yy xx = Jump to address $xxyy in the current bank.

    8D zz yy xx = Long jump to address $xxyyzz.

    94 yy xx bb aa = A conditional jump? It checks the value at $xxyy and if it’s zero, jump to $aabb. Example: 94 26 02 0B 8D 8D B1 90 AB = check if $0226 is zero (looks like it’s related to if you beat the game or not?). In my case, it was zero, so jump to $8D0B. When I forced it to one, it skipped that and read the following “8D B1 90 AB” command as documented above, which made Intanya give some end-game speech with all the other characters there.

    96 yy xx = Jump to address $xxyy, not sure what makes this different from 8C.

    9A xx yy … 00 = Some sort of bit setting? Ends when it encounters a 00.

    9B xx yy … 00 = Some sort of bit checking? Ends when it encounters a 00.

    AB xx = Skip the following xx bytes.

    B6 bb aa = A conditional jump for dialogue options? It ANDs aabb with #$3FFF, then compares to $1D0F. (Example: B6 BC 82 96 F0 8E BE … = take 82BC, AND with 3FFF to get 02BC, compare $02BC’s value to $1D0F’s value. They were equal, so it skipped the “96 F0 8E” jump and went to the BE command as documented below)

    B8 bb aa dd cc … yy 4x = Store values aabb, ccdd, etc. in memory starting at $7E:FC7C. Will continue to read until it finds a pair of bytes that has the 7th bit set. (i.e. returns a non-zero number when ANDed with #$4000). This is for loading dialogue options into memory.

    B9 bb aa dd cc … yy 4x = Same as above, but does not initialize address index back to zero and instead continues where the above left off.

    BE aa bb … 00 = Display or hide dialogue options. If the highest bit is set (8x), then display it. If not set, then hide the option. These are indexed relative to the order they were loaded in by a B8 or B9 command.

    C0 yy xx = Set a flag of value xxyy in RAM around $7E:FE78.

    C2 yy xx = Check if any flags in $7E:FE78 are greater than xxyy? And then OR xxyy with $8000 and check again.

    C4 yy xx = Check a flag of value xxyy in RAM.

    C9 = A wait or handing control over to player?

    Hopefully this helps with the script tools. Let me know if I can do anything else.
