Millipede 1987 cartridge thickness

Thanks for the info. Will take care when inserting then.

So I have the 1988 Atari 2600 release of millipede:

However, whenever I put it in my light sixer, it's so tight. It still fits but I have to push harder than I have to do with other games.

 

On further inspection the cartridge is slightly thicker on the sides than my other games.

 

Why is this? Will it damage my Atari?

Wow, didn't know that! Good to know my controllers aren't missing vital pieces. Thanks for the help!

[Atari Retaining Ring?]

So here's what happened:

 

I bought an Atari 2600 joystick. It worked fine, but there was a rattle inside. Open it up, nothing in the main chassis. Then I realise the boot is the part that's making the rattling noise. I take out the plastic stick, and out falls four pieces of what looks like a black plastic ring. From what I researched, this is probably the retaining ring. However, after reassembling the controller, it still works, and it works better than it did before!

 

If what I did was wrong, let me know.
