Since the tutorials were made I've added Kees van Oss' build suites so you're probably better pressing F5 to test rather than following the videos to the letter. The tool should build and run your game automatically now so try that and see if that works

Hi Jonathan,
Fantastic piece of software and an even better tutorial. However, I seem to be having the same issue, where, after building the project I encounter the emulator starting up and then simply resetting. Do you think you could reply with simple, bullet-point steps for the exporting process, please?
many thanks,
Marc
Try downloading version 0.7.8 and see if that fixes the problem. If the emulator is still coming up and then exiting then there might be a problem with that emulator. However, I've just added an option to export .tap files so you should at least be able to select File->Export game to create a file that should run on another emulator
