CPS1 "Dash" & Kick Harness Upgrade

Had a couple projects I needed to finish recently.  This time its more hardware related.

I picked up an old Street Fighter 2: Hyper Fighting (aka Turbo) for a good price, but noticed that this board was converted from a Street Fighter 2: World Warrior, rather than Championship Edition which it would normally be converted from.
(B-21 chip on the C-board, great for conversions!)

BITD the Hyper Fighting version was sold as conversion kits, and was recommended to be installed on the Championship Edition board-set. But you know those wiley Arcade Operators, always looking to save a buck!

The SF2:CE A-boards had a faster oscillating crystal (12mhz, rather than 10) to make them "Dash" versions, and are great candidates for a multi-CPS1 kit that is rumoured to be in-development.

I was recommended this crystal (link here) to install on my board, and after de-soldering the old 10mhz Crystal and solding the new one, everything turned out great. The new crystal made the game feel smoother, especially in the slow-down areas where framerate seems to take a dive.

Afterwards, I wanted to do a Kick Harness adapter to go from the old CPS1 harness, to the CPS2 kick harness. I decided this because most of my kick harness set-up revolves around using CPS2, so it made sense to only support one type of harness.   I could have just got a cable adapter, but I felt it would be cleaner and less parts to handle if I put the CPS2 adapter onto the board itself.

I am very happy to how it turned out, and am looking forward to converting this to a multi-CPS1 board whenever those kits are available. For now, I can enjoy a bit of Hyper Fighting!
