| **Remember to save your work periodically**, either by pasting the text into a file, or using the Save button. Tip: the Save/Load/Chose File buttons work really well with a directory that is managed by Git. | **Remember to save your work periodically**, either by pasting the text into a file, or using the Save button.

| For some examples of games and demos, see the [[#Resources]] section above, and also take a look at the http://txt3.de/ website - which uses an earlier version of the [[6502 Emulator|6502 emulator]] used in this course. The "Open Project" control on that page provides access to some interesting and inspiring code (check out "Skier", for example). You can copy-and-paste any of those examples into our SPO600 [[6502 Emulator]]. Be sure to check for permission (or licensing terms) before copying any code from that site (or any other source) and incorporating it into your code. | For some examples of games and demos, see the [[#Resources]] section above, and also take a look at the http://txt3.de/ website - which uses an earlier version of the [[6502 Emulator|6502 emulator]] used in this course.
