Mike, the creator of the HAS has just opened pre-orders on pre-assembled versions of his CPS2IOI board. This device is meant to be used with Markus’ CPSHDMI project, allowing for a fully-functional CPS2 without a supergun!: https://homearcadesystem.wordpress.com/cps2ioi/
The pre-order page has options to add a kick harness, controller adapter and more, starting at around $45 USD for the pre-assembled board itself. I recommend getting the custom short kick harness as well.
The design files and BOM are also available to download for people who want to make their own. Please keep in mind, maknig these in low quantites can cost almost double what Mike’s charging for the pre-assembled boards: https://oshpark.com/shared_projects/Zjf0XU71
Anyone looking for a different style adapter can check out Sentinal Supergun creator Frank’s version here: https://www.retrorgb.com/cps2-cps3-digital-av-interface-helper-pcb.html
Here’s a tweet showing how mine looks:
Got all the parts in for one of the two CPS2 I/O boards! This, combined with the CPSHDMI kit and I can use CPS2 on a flat-screen without the need for a supergun! More info coming soon…
…but until then, anyone feel like selling some short kick harnesses to match? See last pic. pic.twitter.com/KfCCA3YWzy
