Alright, here goes nothing. The Gaster Ghost is here! You can read detailed instructions and download him from this page, but just in case, I’ll replicate it here.

What is a Ghost, you may ask? An Ukagaka 伺か or Nanika 何か, also known as a Ghost, is a character (or set of characters) that sit on your desktop and keep you company. I post about them a lot.



Features

Gaster will say random things as he idles on your desktop, and his dialogue will change in a whole lot of ways as you continue to interact with him. If you ask him about Alphys, he will start to say random things about Alphys, for example. You can also make him be silent if you don’t want him bothering you.

lot of ways as you continue to interact with him. If you ask him about Alphys, he will start to say random things about Alphys, for example. You can also make him be silent if you don’t want him bothering you. You can pet Gaster by stroking his head with your mouse (don’t click, just move the mouse in the right area), or punch him by double-clicking his face. The more you do each action, the more his reactions to each will change.

Gaster can also do standard Ghost functions, such as set a picture as your wallpaper, empty your recycle bin, tell you your computer’s stats, check if you have new email (if you set your POP settings in SSP correctly), update himself remotely when he has new material, and if you drag and drop a compatible site on him, he’ll add it to Headlines or RSS feeds, and you can see if there are new posts.

Gaster has a pretty complex relationship system, wherein he’ll track how you treat him and change his reactions and dialogue accordingly. Even small actions may change some things without you knowing.

You can keep track of your interactions with him through a stat menu. You can also reset Gaster back to his default state if you want to start your relationship over with him. Certain things, however, he may not forget…

While Gaster may not say a lot randomly while he’s idling, he has an enormous amount of text in his menus. Specifically in his ask, item, and act menus. He has multiple responses to almost everything, so you may be surprised by new dialogue. Asking him things can sometimes lead to unique interactions. The act menu will change depending on what you do to him. Whether or not he’ll accept items and how he’ll react to them depends on your relationship with him. Certain items are permanent, while others are only accepted under certain circumstances, times of day, or a limited amount of times.

Download, installation instructions, and user guide continue under the cut.

How to Install

Basically, you can’t run Gaster (or any Ghost) by himself - you need a baseware program first. SSP, the program most commonly used for running Ghosts, is compatible with Windows XP, 7, 8, 10, Vista… probably anything more current than XP. If you’re using a Mac or are running Linux though, there are still options for you, but I can’t personally tell you how to get them to work. I have heard from people who did get Ghosts running on their Mac using one of these methods though, so it IS possible. But Google Translate will probably be your friend here.

Macs - Ukagaka on Macs, NiseRingo, PlayonMac+SSP (10.6 or above), WineBottler (I think?)

Linux - NINIX, NINIX-AYA

Android - Ukagaka for Android (I have NOT tested this, so…)

If you are using Windows though, just follow these directions and you’ll be set in no time! If you already have SSP installed, you can just skip to the end, haha.

The first thing you’ll want to do is download and install SSP. While the site is in Japanese, just look for the “complete install package” download on the left. Download it somewhere and install it. When that’s done, run SSP.exe, the program with the little bell icon. A catgirl named Emily should pop up and start talking to you in Japanese, and end up throwing up a big menu. For now, ignore all of that, and just close the menu when it appears. You can also hold down a key to speed through her text. She’s the default Ghost that comes with SSP, if you’re curious. Right-click the catgirl. It should bring up a long menu. If it’s in English, then you have nothing to worry about. If it’s not, go to the fourth option from the bottom, set it to English, then close the catgirl and reopen her. The right click menu should switch to English. The catgirl ghost will still be in Japanese though. Download the z_undertale.zip, which is the balloon Gaster will be using. You want to do this first so he’ll use the right balloon when he first appears. [Mediafire mirror]

Drag and drop the z_undertale.zip onto the catgirl’s face. It should look like she’s installing something. She might tell you the balloon’s name when she’s done. If you right-click her and go to the Balloon tab, you should hopefully see the Undertale balloon listed. Download the z_gaster.nar file. This is the actual Ghost. [Mediafire mirror]

Drag and drop the z_gaster.nar file onto the catgirl. She should again look like she’s installing something. She’ll probably say Gaster’s name when she’s done. Right-click Emily and go to the “Change Ghost” tab. You should now see Gaster listed! Switch over to him and you should be ready to go. If he’s not using his balloon, you can use the Balloon tab to switch him to it.

If you already have SSP coming into this, then all you have to do is drag and drop his respective balloon zip and nar onto your current ghost, and he’ll install. If his balloon font looks odd, make sure you have Determination Mono installed.



Quick User’s Guide

You can stroke his head with your mouse to pet him, or double-click his face to hit him. It’ll ask you if you’re sure you want to hit him (for the first time, anyway), so you can’t do it by accident if you’re worried.

Double click his body to open his personal menu. This is the menu with the unique menu options I outlined above.

Right click his body to open the general SSP menu. You can use this to change Ghosts or Balloons.

To check for updates, select it from his functions menu, right-click him and click Check for Updates from the SSP menu, or hit Ctrl-U when he’s the focus. He should check for any new stuff and download it automatically. I usually post about new updates in this entry. If you run into any bugs or problems with him, you can leave me a comment there and I’ll see if I can fix them.

If you want him to stay on top of your windows, right click him, then go to Options - Preferences, then the Ghost(2) tab in the big menu that pops up. Check “Always Show Foreground” and that should do it.

If you want to make him bigger or smaller, right click him and go to shell scaling, then choose the percentage you like.

If he doesn’t seem to be retaining values in his stat screen (like if you pet him five times for example), you can try deleting the aya5_variable.cfg file and letting him make a new one by telling him to reset from his personal menu. You can find this file in the folder where you installed SSP - something like, \Downloads\SSP\ghost\z_gaster\ghost\master depending on where you put SSP, of course. If the aya5_variable file has been write-protected you might also run into this problem, or if it’s in Dropbox. Try moving SSP somewhere else and see if that helps. It’s a very lightweight program.

If you want to uninstall SSP, just delete the SSP folder. If you just want to uninstall Gaster, delete the z_gaster folder inside the SSP\ghost folder. You can also turn on the Uninstall option in his personal menu, then select Uninstall from the right click menu.

Even if you’ve been treating him well, Gaster may still at times be arrogant, self-absorbed, secretive, brusque or sarcastic. It’s just how he is.

Maybe use the tag #ukagaster if you want to post caps of him or anything? I can’t promise I’ll check it but it might be nice to have it all under one tag for others. If you got troubles or have problems you can message me and I’ll see what I can do.
