Re: MiSTer Pi

@Retro-Nerd What an aggressive person! :lol: You didn't refute any arguments and you didn't answer any question, but you gave me a lovely hint. How sweet. Maybe I'll take your advice. After all, I don't want to hurt Taka's business that you're so worried about. I'd rather go back to spending my hard-earned money on consoles, PCBs, and scalers. At l...

Re: MiSTer Pi

it’s nothing to do with a rasp pi. unfortunate name choice. Nobody confuses that. But this "Use a cheap Raspi setup with software emulators (btw. a Raspi 5 istn't that cheap in the first place) and you don't need a FGPA based solution anymore" argument is silly and pointless. Two different audiences. The first just want to play, the latt...

Re: MiSTer Pi

If anyone can sit and play a game for 1 hour and then spot that 1 frame has dropped since starting, he's one hell of a guy. Same here mate, tired of folks banging on about milliseconds and latency which seems a common trait across all FPGA projects. We're all in our 50s.60s now. It's not Christmas 1983 when you got your spectrum and you could reac...

Re: MiSTer Pi

The irony that we’ve moved past scrutinizing emulation cycle accuracy vs. real hardware, but now demand new emulators to exactly replicate an existing emulator… Just goes to show how great MiSTer is. What a time to be alive :) The irony is that, we've had cheap emulation boxes like Raspberry Pi, with pretty good accuracy and not-so-bad input lag a...

Re: MiSTer Pi

It heavily depent whatever means "few" for different people. 5? 9? 11?

Still, if this is only quartz tolerance problem it shouldn't be more than 1 frame per 50 hours (with claimed tolerance at 0.0006% for consumer devices).

Re: MiSTer Pi

Of course the test is pointless. But that's what the Retro Gaming youtuber like to do, for whatever reason. Just comparing things with each other. And then people get it wrong. But such test were made after up to few minutes of running cores. Isn't error at 1-3 frames during period of few minutes slightly to much? No one youtuber made test with co...

Re: MiSTer Pi

if im reading the comments/discord messages right, the testing results from VGE was that 1-2 frames are desynced over a couple hours, when comparing a Classic MiSTer to Taki's Clone. which was later confirmed even console/arcade board to board hardware comparisons would have the same variance, and is within tolerance. and that desync was not unive...

Re: MiSTer Pi

… i watched all videos and didn't see any problems. could you elaborate? I'm talking about differences in framerate/frame pacing/cores speed: https://www.dropbox.com/scl/fi/xgxxqpem50qvqa13hgbnq/Screenshot_2024-09-10-23-30-50-76_d11ae654701a5fadb313ea6fa9a6836f.jpg?rlkey=biykkpqxb2hg6y7myku9wzpwt&st=ceoxtefw&dl=0 https://www.dropbox.com/sc...

Re: MiSTer Pi

Maybe those clone boards are too cheap? Some problems began appearing, like some problems with core speed:

or lack of some features:

Re: Allwinner D1 Possible Future Cheaper FPGA Options

DDR3 is way faster then SDRAM yes. BUT DDR3 also has much higher latency then SDRAM, which could be a BIG deal with systems that was built using SDRAM. No, DDR3 hasn't higher latency than SD RAM. Where you get that information? Actually is opposite. Typical CAS latency for SD Ram at 133 MHz is 7.500 ns, for average DDR3 2133 MHz just below 0.500 n...

Re: Allwinner D1 Possible Future Cheaper FPGA Options

My main goal is to have the MiSTer run on cheaper FPGA boards. Interesting choice. That Kintex board have 256 MB built DDR3 RAM so we wouldn't need extra SD RAM module. Also 2x64 pin GPIO looks promising. We could have direct controller input in place of obviously missing SNAC, but digital/analog output board will be necessary. D1 nor Kintex board...

Re: Allwinner D1 Possible Future Cheaper FPGA Options

My main goal is to have the MiSTer run on cheaper FPGA boards. but I am not sure of how much that would cost (maybe around $50 or so for small quantities, depending on what features it will have). This has always been what kills these kinds of efforts, when folks in the past over the years tried to find "cheaper" alternatives to the mist...
