NanoSave supports Legacy UI, but example UI elements use TextMeshPro, as Unity’s old UI Text is now legacy. To view the examples, install TMP Essentials (Window → TextMeshPro → Import TMP Essential Resources).
All components support TextReferences, so if you prefer Legacy UI, you can switch to using Text instead of TMP.
NanoSave currently supports Game Creator 2’s no encryption and XOR encryption only.
