That one I'm not sure. I got this rom switcher as a kit so i tried to stick with what was in the kit. Something that small certainly would have made the job easier! As for the buttons, if I remember I did take one or two apart and had some success cleaning them, but they kinda get loose the more you take them apart. It probably is an option, but I found it quicker for me to just replace them and keep the old ones as spares/parts. That being said I've used it a few times already and it works great, sounds awesome!

Could you use a BCD switch that controls a 74HC154
