Two minor Inside Playdate doc errors FWIW. Nothing too hard for the reader to figure out though!
playdate.setGCScaling says: “ for the minimum GC time, as set by playdate.setGCScaling().” I think that should be, “set by playdate.setMinimumGCTime()."
And under Profiling Memory Usage, in Figure 5, the description of the Malloc Map refers to white and purple zones, which are actually pink and aqua.
