I notice. there are definitely game engines out there that support the creation of gba games but I know for a fact it does not need to be as difficult as it is for me right now to find the easiest one out of all the bunch shown to me so far on my search for something actually easy to operate. I can't handle having to do everything with code and all this related gunk. I understand it can be a lot to compile these engines together but again, there has to be SOMETHING out there. please, anyone help. this would be great. i am thirsty and dying for an answer.

In general the more generic your engine the less performant it is. Given the lower processing power of GBA, it may be difficult to create a good game engine that can be used for a variety of game types. If you want to develop for older platforms you may have to do the work instead of reusing tools. I've been impressed with GB Studio but it is also pretty limited.
