Mushy buttons and input lag

Post by triticus » Sat Aug 10, 2019 6:19 am

I've got a Gameboy Zero with seemingly slow inputs and super mushy buttons. I really have to crush the start select buttons and I feel like inputs are being completely missed. Could it be as simple as the way the PCB and buttons interact? Maybe I need to get the PCB closer to the front shell? Or could it be a software problem or a pi zero not being able to handle the game? Seems to be pretty consistent across multiple games.

this could/should be a support section post


you haven't given any info about what you've actually got in your build.....

if you have you control inputs via a micro controller, then that could be the issue and you may/should be able to adjust it.....

if the controls are via the GPIO....
then the culprit most definitely is going to be the silicone pad (this could also be the case with the micro controller setup)

I personally have found that the cheap/repro silicone pads that you can get (mainly from China) are just NOT great....
especially the ones for the Start & Select and the Dpad.....

I would look at getting some slightly better made ones....

Clean the contact pads on the pcb board. If the issue persists then try another silicon pads like VeteranGamer has mentioned. Also make sure the screws are not too tight.

I'll update with hardware specifics in a bit. I grabbed a new set of pads from retro modding. They definitely have improved things. I think the buttons themselves are a factor. I'm skeptical of the design of the back of the dpad for instance, it's hitting the raised part of the pad at an angle because of the flat back of the button. I feel like there should be a nub for each direction so it hits more cleanly.

Like the start/select hit much better. But they are not sitting as proud of the case as I would expect. The down on the dpad hits 60% of the time.

yeah, i'd say the buttons definitely play a part. personally, i like the nes style buttons from retromodding to compensate for that mushy d-pad feel. they have a sharper edge (and maybe a little thicker?) so it just feels better to play with, imo. i think its mainly just those cheap buttons and pads that you can get that real bad responsiveness from.
