Re: We must not forget to implement these British microcomputers of the 80s in FPGA

I think FPGAs are becoming more and more popular as they become more capable and accessible to the modern programmer. The more folks who learn to program in Verilog or VHDL, the more we will see these older computers become new again. I was stoked to see that the last issue of Make magazine dedicate...

Re: FM Towns coming to MiSTer?

Ha, I often wonder what the landscape would like like these days if Atari and Commodore had survived. I'm thinking they would have turned out much like now, where Atari's OS is pretty much all open source now, Amiga is still closed, but very awesome and minimal, etc. Instead we are left with most p...

NESmaker mapper #30

I was kind of bummed to realize that mapper #30 doesn't seem to work... (it works, but it is a glitchfest) This is the mapper which is used by the new NESmaker development platform, so it seems like it might be a good mapper to support, as there will undoubtedly be many new games created for this ma...

@djmartins: I mean, if you wanted art, and the mister interface could just search the internet for art for you, then you wouldn't have to do it yourself. if you have ever used hakchi on (S)NES classic, it does this image search for you, and it very much simplifies having the box art for each game.

RFE: box art, manual scans

i have a possible RFE for mister... it would be really sweet if there could be box art and maybe manual scans to associate with each rom for each game. not sure what that would entail... maybe if there was a way to automatically search out artwork, also, like the way you can do with the NES classic ...

@Helloiamgary thanks! i got the email... looks like a pretty good deal. screen claims 2 ms response time, which is pretty fast. I think response time is correlated to in put lag, but the only way to measure it is with a camera that shoots high frame rate, and for some reason it is never included as ...

this is sort of off topic, but: has anybody out there ever been crazy enough to try hacking a video input onto their laptop? I'm guessing this is probably a bad idea, but I just keep thinking about it, because my laptop has a gorgeous screen that is really low input latency, and it would be perfect ...

i wonder if it would be possible or make sense to implement M.2/NVMe support into a future revision of the I/O board? I feel like it would be very convenient to just be able to pop a SSD right into the system, but i also wonder if it would be overkill? I really have no idea how that stuff works, lik...

Re: analog audio

The master clock for sigma-delta encoder is 50MHz. This is a really interesting thing to notice for me. The highest quality digital recorders available record and playback sigma-delta at 2.8 or 5.6 Mhz, and use a so called noise-shaping filter which pushes quantization noise into the inaudible rang...

Re: analog audio

I am actually a big fan of sigma-delta audio. I think it often sounds superior to linear PCM (pulse code modulation) in both high-fi (such as DSD or SACD) and lo-fi applications (such as the NES sample channel). the fact is, if you look at the datasheets of most audio converters created since the mi...
