MiSTer FPGA – Strider [1cc] / Capcom CPS-1 Arcade

Strider has seen some significant improvements since I last recorded a video from the beta CPS-1 core a year ago. Thanks to the work of John McMaster & Loïc « WydD » Petit, the CPS-1 hardware is now fully understood and it is now possible to accurately experience this arcade classic. The major revelation in Strider that came from reverse-engineering the CPS-A-01 is the correct starfield logic, which you can see when starting a game prominently in the introduction and first stage, as well as later portions of the game. Previously this was always done as a estimate of the starfield behavior and never truly accurate. John decapped and took high resolution pictures of this chip, and Loic then spent many months analyzing this while tracing wires and documenting his findings for all to use in both future emulation efforts and even possible chip replacements for failing original CPS-1 boards. In 2021, CPS-1 hardware is now fully understood thanks to this effort.

This video is my first 1cc for Strider. I came pretty close in the previous video so it was easily within reach. Spent a couple hours grinding to the last stage over and over to learn it proper, and now after 30yrs since first playing the game can get through it with a quarter. Felt pretty damn good finally nailing a run, and I made it through with a couple lives to spare even. I played this game a lot in arcades, and now it feels just as perfect at home on MiSTer.

My previous Strider video from the CPS-1 beta: https://youtu.be/x_3yfvfJ8Wg

Here are a list of improvements/changes I’ve noted since the beta:
-Speed
-Input (no longer becomes unresponsive at times because of slowdown)
-Starfield
-No more boxes left where items/points picked up
-Better sound balance

-Possible better color accuracy? (not sure on this one, just noted that it is quite different at parts)
Color comparison points:
Trees in background during boss fight on Jungle stage. (15:04 in beta video, 12:31 in this video)
Sky colors in final stage background (15:31 in beta video, 12:56 in this video)

Check out Nerdly Pleasure’s recent video of Strider on MiSTer for highest-quality unfiltered/raw pixel output: https://youtu.be/6VgpGFYSqp8

There is some noise in portions of this video in grey/purple single-color background areas because of youtube’s re-encoding. My old Strider video has a direct .mkv download link if you’d like to see a cleaner video with scanlines. I won’t be providing the same direct download for this one, since it has no branding like all my videos and could easily be stolen for another youtube channel without me noticing.
