Game freezes at SSS every time I add a new GCT or edit an existing GCT

[(specter)]

All I did was remove the "New Pork City is Wi-Fi Waiting room" code in Code Manager. I then saved it as a .txt and replaced the 'BrawlMinus1.5b' txt file with my new one that doesn't have that code. I then exported it as a .gct and replaced the old one with it. Now the game freezes at the SSS. Also, any other GCT file that I add to my /codes folder -- such as ASF1nk's CSS GCT and PhantomWings's Stage Roster Expansion GCT -- freezes my game at the SSS. It's like my game will not allow me to edit its codes or add new ones.

If it helps, I'm using Gecko OS and Stack Smash. See the thing is Brawl Minus loads up properly and I can do ANYTHING in the game until I'm required to select a stage. The moment I get to the SSS it freezes. And no, it is not because my selmap.pac is too large; I hardly have anything added to it plus my game never froze at the SSS before until the new GCTs were added.

I'm a newbie at adding codes, so I'd really appreciate it if someone could help me figure out what I'm doing wrong. I'll give you a step-by-step of what I did to make NPC not the Wi-Fi room:

1. I opened 'BrawlMinus1.5b' in Code Manager.
2. I right-clicked the code that makes NPC Wi-Fi room and removed it because I have a custom stage that's supposed to go over NPC.
3. I checked all the codes and saved it as 'BrawlMinus1.5b' to my Desktop, then I moved it to my /codes folder to replace the old default 'BrawlMinus1.5b' file.
4. I exported the same file as a GCT and saved it to my /codes folder, automatically overwriting the default RSBE01.gct file in there.
5. I opened the new .txt file to check if the NPC is wifi room code was gone and it was. Checked my GCT with GCTEdit v1.0, and it was also missing the code. So my game should work, right? Why doesn't it?

Code:

Disable Custom Stages
046B841C 48000040

Add that to your gct and it should work

It works! Thanks so much!

Also, another question: How many codes can I add before the limit or something? Because now that I know this works I'm going to try adding ASF1nk's CSS codes and PhantomWings's Stage Roster Expansion codes to this same GCT file.

Also, I never had the Disable Custom Stages code before; why do I need it if I add new codes?

Also, does it matter were in the txt file I place a category and its codes?
