Hi everyone
I've just dived into Pico8 and I'm so enjoying it that I cannot do anything else :-)
I've that small prototype but I've encountered a weird bug with sprite editor I don't know how to fix it.
Maybe you can help?
Here's the issue:

• When I modify some pixels on the sprite editor, it also modifies the map at some specific coordinates
• The opposite is also true: if I modify the map, the sprites are changed

  It's a bit complicated to go on my level design so if you can help solving that... I would really appreciate!
  Thank you and keep up

It's not a bug but a design decision to allow the second half of the map and spritesheet to be used for either purpose.
Where the sprite sheet is 0x0..0x0fff shared space is 0x1000..0x1fff and map is 0x2000..0x2fff if I recall correctly.
I was confused at first when I started out but ya. it's the same data just interputed and viewed differently. allows for trade offs

Hi SmellyFish and thank you for the quick answer. I was wondering that too so I'm glad to know it's not a bug. I'll manage to deal with that constraint then. Thanks

would you mind editing the thread to mark the bug as closed?
(or change the category to move it away from bugs)

If you want to make larger maps check out PicoMap: Large game worlds made easy. It's a separate tool for creating your maps and then you copy the data over into your cart. It's not an all-in-one solution like using the built-in map/sprite editors but it's a really neat tool. Maybe more than you want to deal with when you're just starting out—or maybe not, I don't know—but worth keeping in mind if you want to make bigger things in the future.

Thank you for the advice, looks interesting indeed I'm going to check that.
