Re: Alternative to GPL license

Just a curiosity of mine: isn’t it legal to open source a project through a strict copy-left license such as GPL3 and then relicense the same project to a company with a specific payed license for a commercial product? It’s my understanding that, if you’re the original author of a whole project, I m...

Re: MiSTer updater script

I have just updated to the latest version 1.3.3 and uncommented the line. [...] All went through successfully. Restart of the MiSTer went well. All is working just fine for me! Love your script. It is making usage of the MiSTer so much easier. Good, good, thank you for your feedback. [New Arcade Co...

Re: MiSTer updater script

Version 1.3.3 released Version 1.3.3 - 2018.12.16 - Updating the bootloader before deleting linux.img, moved the Linux system update at the end of the script with an "atomic" approach (first extracting in a linux.update directory and then moving files). Version 1.3.2 - 2018.12.16 - Deletin...

Re: MiSTer updater script

if you log into console, root filesystem (which is linux.img) is remounted to read-write. And then if you replace it, you risk to corrupt something... I agree, but in theory, Linux should distinguish between file handles and directory entries: I mean, in theory the system mounts linux.img in read-w...

Re: MiSTer updater script

I realize you parse the GitHub link text for arcade cores vs other cores, but is there any way to split core updates 3 ways to the folders '_Arcade', '_Computer', and '_Console'? That would make this the ULTIMATE updater script!!! If we go for this, I can suggest four folders: _Computer_8bit and _C...

Good addition! Sometimes i forget to update the cores on SD myself :) Obviously, needless to say, if you like it, feel free to use it wherever you want, i.e. the SD installer or the Wiki. Now, back to something we discussed months ago: I think a menu in the main MiSTer for launching scripts would b...

MiSTer updater script

Hi, I made a small Bash script in order to update all MiSTer cores, including menu.rbf and the main MiSTer Linux executable. Simply put the attached mister_updater.sh in your SD and launch it through SSH. You can edit it (Win users, please use Notepad++) in order to change some self-explanatory vari...

Re: Possibility of sharper HDMI output via integer scaling?

I discovered today that if you build the cores with 1920x1200 as maximum input and output, you can use 1920x1200 resolution with mister, and the new integer scaling will correctly do 5x scaling to 1200. It might be worth building cores with 1200p support going forward. Hi, are you Rysha or Jeebs on...

It's not Altera specific thing. It's common known polyphase filtering. some info is here: https://www.embedded.com/print/4017531 Good, and do you have the coefficients used by default when not using coeff.txt? Do they correspond to coeff_pp.txt? Anyway as far I understand each row is a phase with i...

Re: Possibility of sharper HDMI output via integer scaling?

It seems Polyphase can be turned to Near Neighbor by coefficients. Testing now - and it looks exactly the same as NN. Great news dude! Now, if tests are successful, I believe that, if the right taps/coefficients can turn polyphase into NN for integer scaling, another similar set of taps/coefficient...

Re: Poll about prefered scaling quality

Integer scaling is possible only one ONE axis while another won't be integer. In analog TV era there was no standard for pixel clock, so different systems have different pixel clocks. So in order to represent it with 4:3 aspect ratio non-integer scaling on other axis should be used. Yeah, I was goi...
