Recovering from every checkpoint in the first loop of Gradius (Arcade)

Описание: This video shows examples of how to recover from every checkpoint in the first loop of Gradius (Arcade, JP ROM ver.) It was recorded using the Training Mode in the Gradius Origins collection. I may write or record some commentary about the strategies later, but for now it's just game footage.

For many of the checkpoints, instead of just showing how to reach the next checkpoint, I show how to recover up to the end of the stage without dying. Often this is considerably harder than just making it to the next checkpoint and taking a death. Additionally, because of the rank system, the stages are often quite different when partially powered up vs. starting with no power, so I think it's useful to cover them at different ranks.

A list of timestamps for each checkpoint is below. The checkpoints I think are the most interesting are marked with an exclamation point. (!)
