Use Zen Studio Live as a tight feedback loop

For each example:

1

Create or open a .gpc file in Zen Studio Live.

2

Paste the complete example, not only the body of main.

3

Connect Zen through its PROG USB port, then use Compiler → Build and Run or press F5. Build and Run compiles the script and sends the temporary test build directly to the connected Zen, so it is faster than repeatedly programming memory slots while developing.

4

If the build fails, read and fix the first compiler message from the top before chasing later messages.

5

Use Device Monitor to verify physical input, outgoing values, traces, controller type, and VM behavior while the test build is running.

6

Test with the intended console and controller; a successful compile proves syntax, not device behavior.

7

Program a memory slot only when you want to keep the tested script on Zen after the development session.

Use a harmless test profile before adding automation to an existing large script. Large scripts can contain later output writers, remaps, menus, or gates that hide otherwise correct code.
