...but it does what it should do without modifying the MiSTer Cores. All the best Hey, I didn't mean any offense. Like I said, I was impressed. But doing it without additional hardware doesn't take modifying the cores, not sure why you'd think it would? Like I said, you don't need the Arduino there, you could hook the display up directly to the DE...

Transparency in modern PCs is a GPU function; there is no GPU on MiSTer. Both of those statements are incorrect. Transparency has absolutely nothing to do with an accelerated GPU, and the logic in the FPGA to do it is almost identical to the logic to overlay without an alpha channel. On top of that, if you're getting graphic output from a core, it...

For what its worth, this is definitely not "100% no" -- not even remotely. Moonlight doesn't use any traditional GPU resources -- it just greatly benefits from hardware H264 or HEVC decoding. The DE-10 does have a Neon media processing unit on the HPS side that can trivially do either at the bitrates needed. Even if it wasn't, a H264 or H...

It took MAME a very long time to get them standardized, but when they finally did, it just meant getting the memory addresses or ports mapped properly in the ROM metadata, and they all basically just worked. The Mister core is already handling abstracting input controls via USB/keyboard/whatever, its the right layer to also abstract outputs. I don...

Maybe you want to take a look at what this thread holds: https://misterfpga.org/viewtopic.php?f=9&t=1887 Yeah I saw that -- and was impressed at how over-the-top/rube-goldberg it was. The LTC connector on the DE-10 is connected to the HPS and could be used to access an SPI-based (or i2c-based) OLED directly from Linux without all the arduino c...

It should be possible to support outputs via User IO, but every core that uses them would need to be modified. Given how most retrofit hardware is going to work, to interface with cabinet lights (either RGB or single LED for new cabinets, or higher voltage incandescent/neon/etc on original ones), you'd be basically starting from scratch. There's e...

Main_Mister writes the core name to /tmp/CORENAME when it loads a new core. Arcade games loaded via an MRA will write the 'setname' attribute in the MRA if it exists. (So basically the rom name for almost every arcade core). Oh, that's workable relative to RGB button configuration, then. It'd be pretty trivial to monitor for changes and do a quick...

You might be better with a MISTerCADE which has the JAMMA pinouts built in. That would give you the physical cabinet connection you're looking for. The problem isn't the connection -- that's pretty trivial to deal with. Jamma support makes it easy to drop into a simple, legacy Jamma cabinet, but anything but the most trivial cabs had secondary int...

I'm probably not alone in learning about this project as a result of the Verge article last week. I may be a little less common in that I already had a DE10 setup I was using for another project. That had been back-burnered for a while, so I thought it was pretty interesting to check out MiSTer, since I had (at least for the simple cores that didn'...
