GBA Battery cover coming loose

[sygyzy]

Hi,

I have a Freeplay Zero build that I keep on a side desk in my living room. I hardly play it and no more than 5 minutes at a time. Anyway, last week I picked it up and the rear battery cover fell off. I couldn't see or hear anything break off so when I went to re-install it, I was surprised it wouldn't stay put. All the tabs seem to be functioning but I'll be honest, it's not like I memorized what a GBA battery slot/cover looks like.

Luckily, I have an identical shell and now I can see that there must be something in the top part of the compartment, on the body, that the tab of the cover is supposed to mate to. Even if I switch covers, my FPZ build won't hold on the cover. Does anyone have any idea what this is? Or how it could have broken? Needless to say the idea of transplanting my entire build over to a new shell is not something I really want to do.

Hmm, no. I've not heard of that, and I also don't know what would be missing. Do you want to post some photos?

I wonder if you might just use something like Sugru, poster putty, or velcro in there to hold it shut. Over the years, I've seen many a handheld console using tape to hold the battery door shut, but obviously that's not idea to have on the outside.
