It looks like you're new here. If you want to get involved, click one of these buttons!
We (my son, age 10 and I ) have finished soldering our Meggy RGB Jr and and trying to get the default game ("Attack of cherry tomatoes") woking. Its possible we have bad connections but I have looked many times and do not want to get into re-soldering and damaging. This is the status on startup:
The 8x8 display seems to startup correctly, but the yellow diodes, D0, D2, D3, D4 light-up. My son tells me that correct behaviour is D0, D1, D2, D3 should light-up. If we start playing anyway, circular button labelled b1 or "A" has no effect. Other circular button (b0 or "B") shoots as expected and the four square buttons on left also work as expected. After a few seconds the game ends (because "A" cannot used to play) and yellow diodes start a running display. All diodes light up except D1.
The connections below diode D1 and button "A" look ok.
We have a multi-meter but don't know what to look for to debug these issues.
Thanks for your help.
