SP1 Scrolling: Video Tutorial

Following Derek Fountain’s suggestion, I have prepared a video presentation on my previous SP1 Scrolling articles. Some SP1 background and detailed explanations on how the examples work are included; they are also shown running:

I’m also posting here direct links to the tests’ TAP files for easier reference:

• Test 0 (baseline): TAP file
• Test 1 (randomtiles): TAP file
• Test 2 (sprites): TAP file
• Test 3 (partial-inv-1): TAP file
• Test 4 (partial-inv-2): TAP file
• Test 6 (parallax): TAP file

The video is ~30 minutes long, you have been warned :D

P.S. A small mistake slipped in the video: around 13:05 I say that the fastest scrolling routine is the LDDR one, but it is not. The fastest one is the one with the unrolled LDD loop, as it can be correctly seen in the repo code.
