This was my very first Cave Story mod. It's sort of a practice for me before I get into some REAL modding. Basically, if you play it like normal, then it's Cave Story. However, there is an extra fourth ending that you can achieve which involves saving the lives of King, Toroko, and the Colons, as well as sending you and Curly home with the Sakamotos. This mod is now completed. If you find any glitches or typos, however, I MIGHT release another version. Andwhyisit has ported this mod to the PSP and Mac, which was something I kept putting off until I wasn't finding glitches anymore, so I'd have to have him update those if I released another version. Let's hope I got them all. Here is the original post: Cave Story (4 endings) V0.9 (ORIGINAL VERSION) 12/31/2011

Here are some screen-shots you may view before playing if you'd like: Hello forum! I've been browsing for a while, and finally decided to create an account here. I am here to showcase my very first Cave Story mod. It is pretty much Cave Story if you play it like normal, except that there's a fourth ending! Achieving it will result in saving the lives of King, Toroko, and the Korons! As well as send you and Curly home with the Sakamotos. I have tested it thoroughly, but please report any bugs I may have overlooked.
Spoiler


If you would not prefer to try and figure it out yourself, here's how to get the fourth ending: 


Spoiler
Another limb from the original post: When first entering the Sand Zone, notice one of the tiles above you near the teleporter. Shoot through it, and find your new path. Note that this is absolutely necessary towards getting the fourth ending. If you walk up to Curly before shooting through there, then you won't be able to shoot through anymore, and the tile will be sealed off.
Spoiler
If you notice that the tile you can shoot through seems to be water when you jump into it, refer to the bottom of this post as to why that happens.-- Fixed it without assembly! The tile will be solid but shootable before you either shoot it or walk up to Curly.
After emerging from the two breakable tiles which previously appeared to have no significance, head into Curly's residence to find that your shortcut helped you beat her to her house. Enjoy the alternate cutscene, and then continue collecting puppies as usual. NOTE: It is important that you do the sleeping puppy last. Do all the other puppies first, or else this won't work. Collect the sleeping puppy after retrieving the other four, and go over to Jenka's house. But DO NOT give the puppy to her. Instead, walk out of her house after Balrog jumps into the ceiling, and make your way into the Sand Zone Storehouse. Now, if you got the alternate cutscene with Curly, and brought the sleeping puppy in, then something different will happen. Before Balrog manages to forcefeed the red flower to Toroko, the puppy interrupts him, and is further delayed by King as usual. But before he decides to charge at Misery, you show up. King and Toroko's fates are uncertain for some time beyond this point, but there is no boss fight with Toroko since she never ingests the red flower. So, why does this only work with the sleeping puppy? Because Nene's description says that her dreams have been known to "portend the future." Because of that, she knows something bad is going to happen, and contribute's largely to the prevention of King and Toroko's deaths. Despite what happens, you still get tossed into the Labyrinth, and Balrog moments after, except without the blade. Make your way to the clinic, and find Curly. You'll notice, however, that the dialog suggests that she will be able to recover without any medicine, and by simply resting. The physician still requests that you retrieve the Aure-All, but the alternate dialog does not imply that it is mandatory to help Curly get better.
Spoiler
Please tell me if it didn't do a good enough job of implying that, and tell me some possibly better dialog if you have some in mind.
The reason she's able to get better faster is since you never fought her, the only thing she had to fight was Misery. When coming back into the Clinic, you will find Curly is gone, and has headed to the boulder chamber. DO NOT give the Cure-All to Dr. Gero. If you do, you won't be able to get the fourth ending. Instead, continue through the Labyrinth until Professor Booster falls down. Go down and talk to him, and you will be able to give him the Cure-All. He will be healed, and repair the teleporter for you to get back to Arthur's house. But you will first have to notify Curly that there is a better way out. So you'll be able to go back up to the Boulder Chamber, talk to Curly, and get back to the Mimiga village. After getting back, do as Booster says, and check the seemingly empty Mimiga village, until you find the last Mimiga just before Misery teleports him/her to the Plantation. Where do you find this mimiga? It shouldn't be too hard for you to find, but if you want me to tell you... it's the Mimiga in the Yamashita Farm. Talk to Sandaime, and watch the cutscene. You will then be able to go to the Plantation after the cutscenes have ended. Make your way up to the Jail, and find Sue, Jack, King, Mahin, and Toroko. Walk up to them, and King will tell you to get his blade. Go to the Sand Zone, into the Sand Zone Storehouse, get the blade, and bring it back to King so that he can break them out of Jail. Sue will then bring you to Momorin, and the Rocket parts fetch-quest will take place as usual with a minor addition at the beginning which was inspired by it's partial pre-existence. You might notice that with these events, it is not possible to ride the rocket up to the Doctor's throne without getting the booster back, and returning the Mimiga mask. Before riding the rocket up to the throne room, it may be wise to get the spur and missile expansions from the newly dilapidated Egg Corridor now that you have the booster 2.0. So, when you're done taking care of any necessary business, ride the rocket up, and enter the Final Cave. When you get to the Balcony, you'll notice that those four frenzied Mimigas aren't there anymore. Hmm... wait... How many Mimigas was Curly raising? Four. And how many Frenzied Mimigas are usually there? Four. Hmmm... then where are they? When you're ready, head into the Throne room to face the final bosses. The dialog will be slightly altered, but nothing major. The only real big thing is that since you skipped the fight with the core earlier, and the waterway, the core is a new thing to you, and Misery explains it for the first time. Also, since you rescued Sue earlier, Misery doesn't have her, and she doesn't get possessed by the red crystal, so she isn't a part of the fight with the Undead Core. After defeating it, head out as usual, run through Sacred Grounds, confront Ballos, and enjoy the fourth ending.
Spoiler
It should be noted that when playing this mod, the other three endings should be accessible if these endeavors are not performed. Please notify me if you run into ANY glitches. I did not use any assembly in this mod. But I did need to use a few tileset editing tricks to get some sprites to behave the way I wanted them to. However, some things I would like to do in this mod, I was unable to do, and I think would only be possible with assembly. If someone could help me on getting these things working in assembly, then that would be great: turns out, I was able to do BOTH of these things without assembly! Yay! And maybe consider helping me do these improvements in assembly? Thank you.
Spoiler
1. Apperently, there is one global sprite for all tile types that can be shot through. So to make the tile at the beginning of the Sand Zone shootable, I placed an entity inside the shootable tile. If it were shot, the script would detect this, and destroy the tile. The problem is that I was able to find no tile types that fit these three criteria: a. They were solid, b. You could shoot through them. c. Entities are invisible underneath it. I found a tile type that fit criteria a and b, but not c. If someone could help me hack that in assembly, then that would be great. It's fairly simple, right? I mean, how hard could it be? Turns out, I was able to fix this without assembly. The earliest version in which this is fixed is version 0.99. 2. I am not TOO good at spriting, but I would be able to do it for my life. I haven't done it yet, but I'm thinking about making I've made illustration edits of the pictures of Quote and Kazuma on the sky Dragon, and the fight with the undead core. In the fourth ending, Sue is not being carried in the mouth of the sky dragon, but is instead in the helicopter. Also, she is not part of the fight with the undead core, so I'd need to I've edited her out in those illustrations. Cause I want the illustrations to acomodate the fourth ending. The problem is, The other three endings are still accessible. And I want to be able to add have added more illustrations without replacing any existing ones. Any tips on adding more illustration "slots" in assembly? I don't suppose just sorta "adding" the images to the exe in resource hacker, and expecting Cave Editor to acomodate them will work? I haven't tried this yet, but it probably wouldn't work. If nobody has tried this, nor discourages me from trying it, then I'll try it soon. I tried this, and it didn't work. Turns out, I was able to do this without assembly as well!
Well, please consider downloading and playing it, and give me any feedback you can.Edited by HaydenStudios, 30 May 2012 - 09:23 PM.
