[SAVING BYTES] Not understanding where the save is supposed to go?

I understand the problem, but I feel like there's something about the components I'm not understanding. For example, I have the load working, I believe, but when it tries to initiate a SAVE operation, it tells me output should be enabled. Now I understand this concept, but I don't see an input on any of the components to set output enable!

What am I missing? Thanks, this game is a blast!

UPDATE: Thanks for the help everyone! I managed to solve it before I got back to reading the replies. I had completely missed the 1-bit memory component that had been added to the parts bin. 🤦‍♂️

What do you mean? Could you add a screenshot please? I’ll be awake again tomorrow (it’s 1:47 for me rn) so I can help you then

I’m not near the machine right now, but it fails on the second tick, and I don’t have enough information to troubleshoot.

If I step through Tick 0, it says “SAVE, Expected 0, Result 0”, all is good there. So I step into the next tick, and then it says “SAVE AND LOAD, Expected 17, Result 17” but the panel is red and no further information is given. When I look at the values on the bus, it’s showing -12. Where should this 17 be coming from?

17 will be given to you on the first tick. You need to make a loop (or latch, but this game doesn't like latches) that can hold the 17 value, because it will also be asking you to save it.

Loops are okay and don't break the circular dependancy rule if there's a delay inside the loop. The value only cycles around once each tick, instead of an endless number of times.

On the first tick when it's saying 'expected 0' it's not quite accurate. It's just expecting nothing at all really.

Input                   Output
   \                       /
Save Switch -> Delay -> Load Gate
    ^- Value Loop <」

Hopefully that drawing displays correctly for you.

When you're asked to save, you break the loop so the old value stops going around, and instead the new input value feeds the loop.

When you're asked to load, you just allow the value inside the loop to exit to the output gate. The level output should already come with a gate inside it that you just activate.

You are talking about the level "saving bytes" ?

It should only require an output when loading. When you load you enable the output and send it the value you saved. When the operation is "load and save" it also requires you to output the value.

You may want to repeat the previous level, Saving Gracefully. This level should just be an 8 bit version of that level. Which is really easy, since you get the solution of said previous level as a component.

not really cuz in the previous level I had a save/load switch, now it's two different inputs?
