I have a Ti-84 Plus CE, have a couple games already installed (pacman, dino run, tetrica, tic-tac-toe, and OIRAM). Would I have enough space to download this as well or do I have to make space for it?

what game are you talking about in the first place? and yes you definitely have more than enough room!

Presumably they meant to reply to one of the other topics in this subforum, and hit "post new topic" instead of "reply to topic."

To answer the question, if you keep the games in archive instead of RAM, you can fit quite a few games. If those are the only games you have installed, I would imagine that you would have room for basically any singular CE game. If you want to be more precise, you can check the amount of free memory from the memory menu, by pressing 2nd + mem and going to Memory Management / Delete.

Thanks for the tip! Didn't know I could do that, still new to all this (sorry for the dumb question XD)

No problem! No dumb questions here, unless I'm the one asking them!
