The 6502 was the CPU in my first computer (an Apple II plus), as well as many other popular home computers of the late 1970s and 80s. It lived on well into the 1990s in game consoles and chess computers, mostly in its updated “65C02” CMOS version. Here’s a re-implementation of the 65C02 in an FPGA, in a pin-compatible format that lets you upgrade those old computers and games to 100 MHz clock rate!
The concept
The idea of implementing a CPU core inside an FPGA is not new, of course. In fact, the CPU core I am using is not my own, but was developed as a 6502 core by Arlet Ottens, and extended to cover the 65C02 opcodes by Ed Spittles and David Banks. A big thank-you to Arlet, Ed, and Dave for developing the core and sharing it freely! Links to their original work are on the Files & Links page.

My AdBlockers seem to block the page from running the simulation (which depicts the gates' activations as it runs 6502 code!).
Is there anybody here who can get it to work, or is there a genuine reason for the page being blocked?
As for as I can tell I am not "holding it wrong". =)

What are you, sum kinda boomer? Use uBlock ORIGIN - it's the breakfast of champion blockers.

What makes you assume I do not?
I have "uBlock ORIGIN" (as well as "NoScript") installed.
