GBC Aquired, Time to Mod - tchncs

I don have a large budget so it will take me a while todo much. I don’t have my soldering iron back yet either. What should be my order of action here? Should I start with battery or backlight? I also have pokemon blue on the way.

I would do the screen first, it will improve the gameplay experience a ton.
Alright, where would I buy a kit from todo so? I’ve been looking here: retrogamerepairshop
