    Shameless plug: I wrote a 'remix' a couple of years ago over a Christmas break using WASM+WebGL+DearImGui with better rendering performance, integrated assembler and a couple visualization tools (using the visual6502 team's original reverse engineered netlist data, and https://github.com/mist64/perfect6502 as simulation loop):

    - Z80: https://floooh.github.io/visualz80remix/

    - 2A03 (this was contributed): https://floooh.github.io/visual2a03remix/

    (the simulation generally runs throttled to 1 half-clock-cycle per frame, so don't use it as any sort of benchmark)

    Similar project, gate level emulation of NES CPU+PPU by the Nesticle author Icer Addis.

    It is a fun way to benchmark your system. I managed to get 4.1hz on my 13th gen i5 work laptop.

    Let's see an M-series chip blow that out of the water. ;)

    EDIT - It was 4.1Hz in advance mode. Actually runs at between 22Hz and 44hz depending on each time I run it. Odd to have such a wide performance variation. I will just blame Windows and some power management setting/thermal throttling.

      M4 Max, Brave — 93Hz highest, usually around 90Hz. On Advanced it started at 22Hz & steadily dropped from there into the single digits as it ran. Safari held around 62.xHz. On Advanced it started at 40Hz & also kept dropping.

      My very old i5-3570K on Firefox 153 is running this at 17.5Hz. I'm not sure why a much newer chip would be dramatically slower.

      I got 22-33Hz on an AMD Ryzen 7640U on power-save mode and 50-55Hz on performance mode.

      I'm seeing 34 Hz on a Ryzen 7 3600X 3.6 Ghz with Chrome. 47 Hz in Firefox.

      High 60's to 70 on a Firefox|Fedora|Ryzen AI 9 HX.

      70hz to 75hz on 12th Gen Core i7-12700

      Get about 10 more hz in Firefox than in Chrome which was unexpected.

      88Hz on the M4 Pro

        I concur with that number for Chrome, then 70 Hz with Firefox 62 Hz with Safari

        There it is, about 4 times faster than my machine. The single core performance of the M-series is something special.

          So, yeah, this is wonderful since the ARM architecture (Acorn Risc Machine) is arguably derived from the 6502 by Sophie Wilkins and Steve Furber at Acorn Computers.

    Well I've played the 6502 simulator as a kind on my 6502 Apple ][ clone :) :) :)

    youtube.com/watch?si=XuNgnVc4rf86nIgA&t=42

    it should'be available here to play online too (but haven't tried it)

    I wish these guys would have released this amazing looking 6502 in circuits: https://www.evilmadscientist.com/2016/6502/

      Agree. I would pay for it.

        I haven’t followed progress, but they did say it would likely cost $2k-$4k if they ever produced them to sell.
