If you actually just need a replacement PS/2 cable, it looks like eBay has them for sale.

Monoprice sells PS/2 to USB dongles.

If you have little to no experience with programming at all, I suggest trying the assembly game TIS-100 first to wrap your head around the concepts, rather than trying to learn 6502 right away.

I would pair it with this tutorial, which is really just a bottom-up programming course.

Thank you. I read the entire article and I don’t really understand what the OP is trying to achieve with this post, which no one from that group will read, just as no one from that group has ever played a video game. They just seem like publicity-seeking busybodies with time to kill between complaints about their neighbors to their HOAs.

In particular I still don’t understand why any of this is relevant to retro games. Modern games, sure. But it doesn’t look like they’re trying to get Crash Bandicoot banned from Steam.

I don’t know what this group is and I have no idea what you’re talking about. Most of all I don’t understand why this is posted in a retro gaming community

If this were called Yaiba: Zombie Slayer 2099, no one would be talking about it now. The only thing that makes this game not immediately consigned to the ash heap of history is the name.

How many chip collectors exist on the entire planet, I wonder?

Jump Bug (late 1981) is the earliest. It has an entirely underwater level, and the car moves more slowly in it. It was also one of the earliest platformers, beaten only by Donkey Kong (mid 1981) and a couple others.

Super Mario Bros. (1985) introduced a significantly different mechanic for its water levels from the rest of the game, specifically swimming, and it was about a bajillion times more popular than Jump Bug. But it wasn’t the first.
