    There are no MES files, just txt files in "Misc\Cutscene Text\Sonic\1 Intro". Unless you're talking about these files, in which case I tried copying them to the system folder in the mod folder and nothing.

    Just to be on the safe side, I copied the text file multiple times with the following folder structures (I didn't think the last ones would work, but whatever):
    system\Misc\Cutscene Text\Sonic\1 Intro\English.txt
    system\Cutscene Text\Sonic\1 Intro\English.txt
    system\Sonic\1 Intro\English.txt
    system\1 Intro\English.txt
    system\English.txt

    And yet, Sonic's first line in his intro cutscene remained unaltered. So I guess I must be doing something wrong?

    Here's my mod folder.

    You're not reading it properly, ignore the parts that are not bolded.

    Oh, didn't notice that the second part of step 3 wasn't bolded. Derp.

    Works now. Thanks!

    I guess I'll post this here.

    [youtube]http://www.youtube.com/watch?v=11sQUywrnUw[/youtube]

    A while back I mentioned that the original Japanese version released on the Dreamcast included an exclusive cutscene that goes unused (EV0134). This file was removed from every other version of the game. I managed to load it up by locating the table/struct that is responsible for the cutscene sequence after the title screen.

    As I mentioned before, I think this was meant to take place after Amy completes the Hedgehog Hammer and before she enters Hot Shelter, somehow. This doesn't make sense in the context of the scene I don't think. So this might've been originally the cutscene that plays when Amy completes the Hot Shelter (meaning there might've been no Tikal flash back at some point). Why they removed it is anyone's guess.

    Since this is the hacking thread, and I don't think it was mentioned before, the table for the cutscene sequence in the Japanese original is included at 0x8C1D6178 in 1ST_READ, and the function that specifically loads up the event file is at 0x8C04C73E. In the PC version, the table seems to be located at 0x913AE0 in sonic.exe. Each entry in the table is using a struct like this:

    data.w <- stage id
    data.w <- act id
    data.w <- character id
    data.w <- event id
    data.w <- param 1 (?)
    data.w <- param 2 (?)
    data.w <- param 2 (?)
    data.w <- null terminator (FFFF, seems to only be used in the Dreamcast version)

    That is an amazing find. I actually posted the voice clips she uses in this scene on TCRF a few months back, but I didn't know there was ever a cutscene animated for them. Here's what they translate to:

    ???????????????????…
    I never thought I'd come back here again...

    ????????????????????????…
    I wonder if your siblings are still here in a place like this...

    ??
    Hm?

    ??????????????????
    Did you hear a voice/cry from above just now?

    Let's go take a look!

    Working on my art!
    Interesting. So this cutscene then likely would have taken place right before the final Zero boss then? Wouldn't have made a whole lot of sense being inside the ship though since you get there by boat, maybe that's why it was cut.

    It might've been intended for if you went back to the Egg Carrier via the Chao Garden warp instead of with the boat.

    The warps are disabled at that point though, so you can't go there that way. The cutscene doesn't play if you force yourself inside the carrier at that point either.

    Or perhaps Amy would originally have gone inside the Egg Carrier to look for the Flickies shortly after arriving, then heard the sounds and went outside to check, cue the Zero boss fight. But then Sonic Team felt that players would be annoyed to be made go inside for no reason other than seeing a short cutscene and then back outside, so they skipped it and had the cutscene leading the the boss fight trigger right away.

    Or alternatively, it would have been an optional cutscene. After returning to the Egg Carrier, players would have been able to look around. Going to the boss fight arena would have triggered the Zero fight and cutscene, whereas going inside would have triggered that cutscene. So its purpose would have been telling stray players where they have to go. But then Sonic Team decided to just have the pre-boss fight cutscene trigger as soon as the player returns to the EC, so that cutscene went unused. Perhaps they did this change because they felt it would have been a better way of preventing players from straying, or because they decided to do away with optional cutscenes (for fear that some players would have been mad at accidentally missing some cutscenes, maybe?), which would explain why they scrapped the optional cutscene that would have played when Gamma exits Final Egg before finishing it as well.

    Hot Shelter could have been the last stage at one point.

    I'm not getting Youtube links appearing right on my laptop, just a white screen.

    Found the vid on Youtube site though. Nice find. Like it also uses the 'The Ocean' theme as well. I guess that was the mission theme when characters went back on the downed Egg Carrier.

    That makes sense, it is noticeably harder than Final Egg and like Gamma and Big's is a fuller display of Amy's mechanics.

    My guess is they wanted Hot Shelter to stream into the story better so had Amy use it as a detour to escape earlier on. They couldn't save Final Egg's pointlessness though.

    The only other guess is that Amy was supposed to enter Sky Deck or another unused Egg Carrier situated stage.

    Unrelated to the topic at hand (nice find, by the way!), the results of the poll mentioned here:

    appear to be overwhelmingly Windows 7+, so once I get around to it, I will begin upgrading this experimental project to Direct3D 11 and eventually merge it into SA Tools. :eng101:

    Just a wild theory, but this could perhaps explain the presence of water in Hot Shelter, i.e. it could have originally been flood water from the carrier crashing into the ocean, but was later reworked into an aquarium.

    Another thing I forgot to mention. You can actually load up those event .prs with any character and any stage. The event file itself contains the dialog text, camera movement data, animation data, and code to make it work with the external functions in 1ST_READ. It's funny because when I initially loaded the event file it was just with Sonic on top of the Egg Carrier. When the animation of Amy looking up appeared (which the data is exclusive to this event file), it changed Sonic's mesh to Amy's for the duration of the animation. So there could be some unused assets (models, animation, etc) in the other event files that go unreferenced.

    Has anyone actually documented what each of the event .prs files correlate to? I wonder if there are any more events/cutscenes that go unused but are still included in the game, like this one.

    In the Autodemo, Hot Shelter isn't even present, either - no assets, not even level slots. It could be that either:

    1.) It was developed last, which might indicate that it could be a final stage for Amy (as it is a final stage for both Gamma and Big), if development went remotely in how the levels were meant to be played;
    2.) The stage was a really late addition and it shuffled around the level order, resulting in cut cutscenes such as the one just posted.

    It's worded a bit confusingly but as long as you know which scenes take place after each stage you should be able to read it. :)

    Hot Shelter is mentioned by Tikal in some of her voice clips. I think it was planned by the time they did the stories, but the stage itself just got made later than the other ones probably because it's the only one Sonic doesn't go to.
    I mean, the music for Act 2 was used in part of the game's announcement video after all.

    In general I think Act 1 was designed more for Big rather than Amy. There's tons of leftovers in Amy's version of HS Act 1 that indicate she wasn't the first character the act was designed for.

    Completely unrelated to the previous posts, but I figured I could as well share this little thing. I just corrected the transparency issue in the game icon:
    [​IMG]

    Here's the fixed icon:
    http://www.mediafire.com/file/b4sd7lesqs5kb7m/Fixed_SADX_icon.ico

    And here are the executables with with the fixed icon:
    http://www.mediafire.com/file/nreiz2wvzi6ja91/Fixed_SADX_icon.zip
    It's the US exe, so it's compatible with the mod loader.

    PS: Does anyone have the Steam version's icon? It would be neat to be able to put it on the 2004 version, for people who want their SADX and SA2 to have matching icons :v:
    Besides, it looks plain better.

    I have the one from the Dreamcast Collection release, which is in the same style (read: it's the box art):
    [​IMG]
    ...but it has a transparent frame (unlike the SA2 icon), and only includes one resolution, which is pretty low compared to the SA2's highest res icon (64x64 vs 256x256). So I was wondering if the Steam SA1 icon had a higher res?

    I checked the Steam version executables with Resource Hacker it's the same 64x64 one that the Dreamcast collection has.

    Oh. Oh well, it was worth a shot. Thanks for checking.

    In that case, here are the 2004 executables with the DCC/Steam icon for anyone who wants them:

    SADX Dreamcast Conversion, The Emeralds' Awakening
    To be fair that particular icon is pretty easy to recreate. It's just the title screen background with Sonic slapped on top, both of these can be easily found online. If nobody else does it I'll make a high-res icon for it sometime soon.
    I've always wanted to change that SADX icon, but I'm not a big fan of editing the EXE file. I think the point of the Mod Loader is partially to help people get away from EXE mods, which may have all sorts of issues and aren't compatible with each other. Changing the icon feels like going back to EXE mods again, even though it isn't as invasive as an actual EXE mod. If the Mod Loader ever gets the functionality to patch the EXE with an icon of your choice that will be a lot better though.
