Still in a process of downloading and reorganizing my costumes to fit the new format, but from what I gather in the comments you say a default SSS or expanded one will work, but just won't display the additional stock icons? Because that's fine with me, I'm too lazy to change them all anyway and nobody really looks at em.
Hoping I'll have everything setup so I can start messing with CBliss on its own tonight, then move on to adding in the extra character slot over the next couple days.

Awesome update! I'll download the new pack and continue fishing for textures to fill up my slots, then I'll test it all at once when I've got it setup and ready to go.

Just an assumption, this probably isn't compatible at the moment with your extra slot + cosmetics, right? Because I noticed that ghost slot you used for CSS pics for Roy is completely empty in this version. I assume it'll still work without cosmetics though, but I'm just gonna work on getting this setup with some extra costumes before I go into combining the two.

This looks amazing! I'll be pretty eager to give this a test drive, makes me wish I wasn't so busy lately so I could set it all up. I still need to play around with the recent extra slot updates. But still this is awesome, it's nice to see an expanded costume selection finally coming to light!

I'll do some test runs of the 2 gcts to see how it goes. Just a heads up, my crashes didn't occur with Roy in the match, they just happened at random when entering the CSS.
But anyway, I'll get some time in this week when I can.

Looks like you're making some sweet progress. I'll probably wait until you upload the start up pack before I mess around with it, just makes it easier for me to understand personally when I see how it's all put together.
I still get the occasional freeze now when using those codes, it seems to happen at the end of a match, when trying to return to the CSS. It's happened 3 times total so far, but considering how much playtime I've put in compared to those 3 freezes it hasn't been that bad. If it starts to get worse I'll just replace my save file with my fresh one. I don't care about statistic data or anything so it's no skin off my back.

That HUD is downright gorgeous, and it's great to see you're getting the separate stuff working. When you say stock icons, do you mean separate ones ingame? Or just during the SSS. Cause I personally don't think the SSS ones are a big deal since they're only there for a brief moment, but if we could get unique stock icons back like in melee and 64 that'd be pretty neato.

Ah I see what you mean there. I'm gonna try throwing in Pit's default file and see if it'll work then. Also gonna give a few other popular PSA's a shot with this when I have some time after.

Edit: Yeah, if you just include the default FitPitFinal file with any Pit PSA it'll allow it to do the final smash as usual, just tested it with Waluigi and he's working fine now.

Edit2: Got my first random crash from going between the CSS, main menu, and trying to go back into the CSS. Since I don't typically exit out of the CSS much I'm not worried about that crash, but I'll let you guys know if I start experiencing them anywhere else. I've done quite a few matches as various different psas though and I'm not getting any other issues.

Tried both Goku and Waluigi, both of them can't use the final smash. It doesn't crash or anything though so it isn't a horrible bug, just inconvenient.

EDIT: oops, nevermind stupid me. I just forgot the ft_ in the module's filename, that was dumb of me. Gonna test Link out again in a bit.
EDIT 2: Yep, Link works fine too.

Aside from that though Mewtwo works just fine, probably not going to test any others for now.

Oh sorry, I was just editing my last post here to avoid double posting. But yeah it's working fine now. Great stuff here, I'll post back if I find any issues or glitches going on.
Thanks for putting this up and helping me out with my issues!

Edit: Not sure if it's related to the P&P modules or the codes used here, but characters based on Pit cannot use their Final Smash. It just uses their base special move instead and the Final Smash never gets activated. That's the only bug I've got so far.

Alright, gonna give it a try again. I figured something was buggered with the codes since Marth and Roy show up as DK CSPs on the CSS when I figured they'd both use Marth's. Anyway, I'll set those codes up again and give it another try. I'm using Thany's Decloned Roy as suggested in the tutorial, following it all exactly as is to see if it'll work before tweaking it to my own preference.

EDIT: Ok, using the set of codes you just posted the CSS is looking right now, so I'm assuming something is buggered up in one of the tutorial codes. Still getting a crash whenever I try to load a stage as Roy, I'm using the set of files with Thany's De-cloned Roy and the Marth Plug and Play Module linked in the tutorial, with its id set to 0x27 like it says to in the tutorial. Gonna try to switch around files a bit and see if I can get normal Marth to load from it using fitroy files.

EDIT x2: Now I see the problem, I didn't realize there was a difference between module ID and Character ID. You should probably make a little link to Phantomwings tutorial on how to use the plug and play modules there too, just so people have an idea of where to change the character ID since the module ID seems more obvious when first opening the file.
It's working fine now, there doesn't seem to be any glitchiness happening yet aside from the CSS having a little lag when reloading. Gonna play around with it for awhile and I'll report back if I find any issues.

So I tried using the example codes in the tutorial, just to see how glitchy the experience would actually be, and I'm getting Marth's CSS slot appearing as Donkey Kong on the CSS (still loads Marth however) and the extra slot looking like Donkey Kong and causing a crash when trying to load a stage.
Is there some kind of error in the example codes? Or would other codes perhaps interfere with this? Just kinda curious to what you've combined this with since you've seemed to have a good experience so far.

Well it sounds like people are having a good experience with these in general, and even if saves corrupt they can easily be restored so it's not like there's any permanent damage to be caused.
It's too bad there isn't a code that could just prevent saving altogether to avoid the corruption, I mean it's not like we even need to use saved data outside of taking snapshots.
I'll definitely be giving this a shot later.

It's interesting to see progress being made with modules and towards the elusive Clone Engine again! Even getting those 7 slots to work would be amazing, I can't really think of 7 quality movesets I'd want to be standalone anyway, so it sounds like more than enough to me.
I'll just be eagerly lurking to see what more comes of it, just wanted to cheer you guys on and let you know that I appreciate all the progress that's coming from it.

I'd try one method and if it doesn't work, try the other.
