Re: Genesis Core

I assume cart saves are not implemented yet? I tried with Sonic 3 & Knuckles and couldn't get it to work.

Re: FX CAST Atari ST core

Are you planning on releasing the source code for the 68k so that other projects can benefit ? I do, but it won't be today. I'd like to wait a few days, just in case the public release exposes any possible bugs in the 68K core. I also need to think and decide which open source license to use. I'm n...

Re: FX CAST Atari ST core

Out of curiosity - did you use the designs recently uncovered here: http://www.chzsoft.de/asic-web/ in order to replicate cycle perfect chips? Not really. I made my own reverse engineering that included chips decap long before. Also, unfortunately, the archive includes schematics for a single chip ...

Re: Menu select button changes between cores

To borrow somebody else's wording: OK is consistently the left button, and BACK is consistently the right button This should map across consoles that share a controller format, eg NES, genesis, tg16, etc pretty consistently So in the case of genesis "A" should be "OK" and "B" should be back For TG-1...

Re: Menu select button changes between cores

The problem is that in many games (such as Super Mario Bros) when you reverse the buttons it's very difficult to play (at least for me). Instinctively, the left button is fire/run, and the right button is jump. It's just muscle memory at this point :cheers:

Re: Menu select button changes between cores

It is pretty much consistent: first button is select, second is cancel/back. After almost 2 years of MiSTer existence i didn't find any inconvenience. So what you're saying is the only way to have a consistent select button in the OSD is to map the gameplay buttons incorrectly for certain cores (ie...

Re: Genesis Core

Thanks for the newest update Sorgelig! Really glad you were able to make the scaling configurable.

The only issue I've noticed so far is that in Gauntlet 4 the movement is very slow and choppy. I haven't tested it in any earlier builds so I'm not sure if it's a regression or not.

Re: Poll about prefered scaling quality

(1) I actually do know what I'm talking about. Not "having a strong opinion about something I haven't tried". I've written several crt style scanline shaders for retroarch and MAME. I've had to worry about proper interpolation and how to balance sharpness vs shimmering. Also I'm a mathematician. So...

Re: Possibility of sharper HDMI output via integer scaling?

I know that you know, but just in order to have a common and established frame of reference with everyone in this discussion: this is scrolling shimmering There is no noticeable shimmering as i've already told. So, scrolling is like bottom Mario. That's setup-dependant, while we had no shimmering o...

Re: Poll about prefered scaling quality

I've seen plenty of shimmering on other hardware, but I do not see shimmering with NN scaling on MiSTer in the Genesis, TG-16, NES, or SMS cores. That proves you don't know what's happening here: The TG-16, NES and SMS cores are STILL safe from this horrid NN scaling method. Nope, I have custom NN ...

Hi, I've just recently discovered MiSTer. Well not really since I've followed emulation and fpga projects since the 90s. But I'm currently looking to source some of the needed boards and make a purchase. I don't want to come across as abrasive, but nearest neighbor scaling is just stupid in a proje...

Re: Possibility of sharper HDMI output via integer scaling?

I compared Sonic (JPN) version for the latest core vs the version from the 10th, and the smoothness of movement for the clouds look identical. That's because your 4K display's native resolution is 3840 x 2160 pixels, which is an exact multiply of 320x240 !! It's pure LUCK that you can't see them. B...

Re: Possibility of sharper HDMI output via integer scaling?

As was already mentioned earlier in this thread, this scaling option can only be set at compile time. So it's either one or the other unless Sorgelig is willing to start providing two builds. I think all those horrible video artifacts you're seeing have everything to do with the 1360x768 monitor yo...

Re: Possibility of sharper HDMI output via integer scaling?

So here's where this NN stuff originated. So sad it's by default now on Genesis core... I hope it does not propagate to other cores, really.

Agreed, the Genesis core is looking better and better. Every game I've tried has worked well and the image quality is stunning :D

Only issue I've noticed is the audio crackling in certain games (Castle of Illusion, etc)

Unable to register due to "suspicious" email address

Hi,

I know somebody who has been unable to register on this site because all the emails he has tried are being flagged as suspicious, including his official ISP address. Is there somebody that can help resolve this for him?

New Genesis release uses NN scaling. Scanlines effect suffer a lot with this scaling, so i had to re-work it.

Re: Possibility of sharper HDMI output via integer scaling?

Scaling algo is set at compile time. There is no way to change it in runtime. As for quality - it depend on picture. The sample you show is kind of photo where separate pixels aren't matter. But if HDMI resolution will be smaller and there will be text, then you will see that some scaled pixels are...
