Today I have been working on getting my MiSTer FPGA running. I've created a guide for what I have done so far and attached to this document. If you don't know that a MiSTer FPGA is, it's bacially 100% accurate gameplay on legacy devices and does not use emulation. The hardware is programmed on a device by device basis in to a Field-programmable gate array. The hardware is known as core's and you load what you want very easily. It's trumps emulation as it's not software based in terms of how emulators are traditionally written. Do a quick google and look on YouTube if this sounds even slightly interesting to you. I was not aware of this product until @Gary brought it to my attention and damn am I glad he did. The document on this thread is complete, but a live document and will be updated with more content as I continue to use this over the near future.

A little tech update; on looking at the best way to get input into MAME whilst it's hidden in the background, with Arcade Sim fullscreen in the foreground (the same as how it works with MFME now). Here I'm experimenting with Lua scripting (the other usual techniques for input faking to an unfocussed window don't work well/at all for various reasons). So this quick vid shows me sending pause, then resume commands, while MAME is 'in the background', and the arcade sim has the foreground focus. My hope is that I can expand on this, to set the input switch matrix states as buttons from the arcade sim side are pressed/released

Pretty comprehensive guide here.

MAME segment alpha display now scraping correctly, including decimal points Next I'll look at both passing keyboard input direct to process (so it can be hidden behind the fullscreen arcade), and then the remapping (I'm playing this in MAME with a really weird set of keys; Ctrl, Alt, Space, Shift, C, 5, 1 etc). I remember having a go at MFME -> MAME automated key remapping before, but I think there was some problem - though I honestly can't remember what it was, it was like 5 years ago at least! Maybe I'll suss it out this time...

In the spirit of avoiding repairing the dishwasher and doing other real life responsibilities, I have the first reels working (24 symbol reels) Really should fix the dishwasher now, though I feel the segment alpha display calling me as the last main visual thing...
