    Ummm, why do you want interlaced resolution?

     

    I've read the comment by a guy who would like to use the Super Nt with his CRT HDTV which only accepts 720i [EDIT: this mode does not exist, my mistake]/1080i. And now I'm just curious too. :)

     

    EDIT: Someone also has mentioned the problem with this game under the Mad Little Pixel video: "I have a similar problem to your Star Fox 2 with my PAL copy of "Street Racer". When it boots up it says "not compatible with Super Scope".

    Kevtris, is the missing interlaced video mode (720i [EDIT: this mode does not exist, my mistake], 1080i) due to some technical issues, or just the lack of time/low priority?

     

    Since you've got the secret recipe for hybrid scanlines from the creator of the UltraHDMI, maybe you could ask him about this Retro Mode mentioned in the overview of the device by RetroRGB as well. Of course, it's more of an artistic expression of how the CRT should look than a perfect recreation of the real thing but I would argue that people would use it on the Super Nt more often than these hqx filters (BTW, I have nothing against the users who like hqx filters! I'm just trying to think of an argument. :P). Of course, I understand that this filtering stuff means nothing to the lovers of the crystal clear pixels (that's fine too, and I'm happy for you).

    Byuu the creator of the cycle-accurate SNES emulator higan said (source): "I think my point about FPGAs got drowned out by countering the marketing angle. I'd like to have a legitimate discussion on "what *is* an emulator?", so I think I'll try again."

     

    Byuu said (source): "What is emulation? I'd like to clarify the difference between FPGA devices and software emulators, analyzing both of their strengths and weaknesses, and have a discussion over what it means to emulate a device. Article link: https://byuu.org/articles/what-is-emulation/ "

    I dont understand what you mean, composite is the analog source and hdmi digital. You dont use hdmi cable to test composite signal.

     

    Maybe there are some communication issues because of the language barrier. Have you tried posting in your native language? A nice post summing up all your problems. Possibly someone will translate it, and you won't have to post over and over again about the same stuff...

    i would be more poised to believe this if not posted on a patreon donation page. anyone notice kevtris dont have one?

     

     

    We have asked him many times to create one here. :) BTW, it was posted on reddit as well: https://www.reddit.com/r/emulation/comments/7q7wgs/nextframe_response_time_16ms_achievable_with/

     

    EDIT: And there's this whole thread devoted to investigating input lag (EDIT2: it is also the link to the post where you will find more details Kosmic about the specs and the methodology used).

  10. Posted

    An FPGA will have no lag in the best case, and minimal lag in the worst case (i.e scaling to HDMI, etc). A software emulator, on the other hand, will have lots of sources of lag built in. There will be the controller interface aspect, the CPU/processing part, and then the video rendering portion. Some of these can be minimized possibly, but if there's an OS running underneath, I think lag will be unavoidable.

     

    Since you said that Kevtris, I think you may find this piece of news interesting. It requires quite a lot of hassle, but still pretty impressive:

     

    "Next-frame response time (≤16ms!) achievable with RetroArch! Latency with RetroArch as good as real hardware!"

    After this is all over I am going to release my "findings" document with all sorts of fine SNES detail that I figured out over the course of the project.

    It's so kind of you that you want to share this, thank you!!! I'm still wondering whether there ever will be a way in the future for you to release the source code and STILL get paid (for the hardware made/sold or support, I would have NEVER suggested that you should not get money for your marvellous work) -- that would be beyond awesome! Well, on the one hand we've got the sd2snes which even though it's open-source allows Krikzz to make some money, on the other hand there are these stories about the unauthorised use of emulators' source code. One has to consider everything... But there is no doubt that open-source is great for preservation and for inspiring people. BTW, what is your nickname doing on the list of MAME contributors [EDIT: Never mind, I found the explanation here]? :P

     

    Why Nt minis composite signal is so bad quality?, original nes and famicom is much much better.

     

    It is the exact reproduction of the NES composite. What do you mean exactly by "bad quality" here?

    If it runs on an SNES it should run on this. If it's just a pins-converter, it obviously won't work.

     

    Someone has asked about the Super Retro Advance again, this time on reddit. It uses its own audio/video output (composite) but you control the game with the SNES controller attached to the console. Is this what you meant by "a pins-converter", Kevtris? Or you had in mind something like the Famicom to the NES converter? Wouldn't the separate video/audio outputs of the SRA cause issues (because the Super Nt would be looking for the HDMI video/audio or something)?

     

    BTW, RetroRGB did an overview of this device, and it seems that it does not suck totally (but it's definitely not good).

     

    EDIT: Well, the manual says that the SRA: "Works with original or third party 16-bit consoles"

    I know you have yet to officially say whether or not you plan to jailbreak the new super nt, but I was wandering if hypothetically you did would it support msu-1 games like the sd2snes does.

     

    Kevtris wrote (Tue Oct 17, 2017 1:06 AM): "I have not tested the MSU-1 but since the SD2SNES itself works 100%, I don't see why this won't work either. I will try it soon just to confirm." I would be (pleasantly!!) surprised after reading this if there was built-in MSU-1 support on the release day. Anyway, the chip is open-source, so let's hope that this might make the things easier for Kevtris.

    "Dissecting FPGAs from bottom up, extracting schematics and documenting bitstream formats

     

    In this talk I describe the basic makeup of FPGAs and how I reverse engineered the Xilinx 7 Series and Lattice iCE40 Series together with the implications. FPGAs are used in many applications ranging from networking, wireless communications to high performance computing, ASIC prototyping and so forth. They would be perfect to create true open source hardware but we would still be bound to use proprietary toolchains provided by the manufacturers. To generate a valid configuration file this toolchain needs to know every single wire, switch, possible connection, logic block and the corresponding bits to configure each them. In other words you are required to have the blueprints of the FPGA in your toolchain to be able to do the place&routing and generation of the bitstream file from your netlist. Naturally manufacturers do not like to disclose this information, possibly because someone could reverse engineer valuable intellectual property cores. I will explain each component used in FPGAs from Lattice and Xilinx, like switchboxes, the interconnect, logic blocks, memory blocks. Furthermore I will talk about how I reverse engineered the 7 Series from Xilinx and the iCE40 from Lattice. At the end I will demonstrate how to create your own bitstream by hand, implementing a small logic circuit and testing it live on a Zynq 7000 FPGA from Xilinx."

    It's a really cool flashcart list (probably the most detailed of its kind)! Thank you! But it has not been updated for quite some time... What about uploading it into some kind of wiki so that the OP would not have to update it just by themselves? Maybe Emulation General wiki? They already have a flashcart section there, and well, to some extent one could say that a flashcart is a "cartridge emulator"... :P

    There's a few things in play here. First, I do not have the "Exact" mixing a real system does, because it isn't possible to have true stereo if you do. This was a tradeoff I made to allow stereo. The DPCM level (i.e. 4011 write, where the DAC ends up after a DPCM sample) affects triangle/noise volume a little bit. I had this in there originally, but took it out to make the channels stereo. If I kept it in, then there would've been channel crosstalk between all the channels and it would've sounded pretty terrible.

     

    As for expansion volume relative to the main channels, it can vary from revision to revision of the famicom, and things like N163 have different value resistors to control volume, so that's why there are sliders. Also, some people tend to like some channels louder or softer than others, as well.

     

    What about adding a separate "mono" mode with this "exact real system mixing"? Then allow the user to choose between "mono" (turn off complex sound customization options here, if this would be necessary) and "stereo". This might be a nice idea, unless you would have to completely rebuild the core to implement such a functionality...

     

    And when it comes to the expansion volume relative to the main channels, maybe create a few volume presets (for the most popular revisions, think of it as of "pallets" but for sound), it's awesome that full customisation is possible, but a few out of the box volume settings might be nice to have as well.

    It's called "deflection".

     

    I've got just two options there "AtariAge" and "Mobile".

     

    EDIT: Anyway, sorry for the off-top, if some knows the answer to my problems, you can send me a private message, that would be nice. I just wanted to share this news about Smokemonster packs with you.

  24. Posted

    48 minutes? Summary plz...

     

    I gave you the timestamp, and I thought it would be best to here it from Smokemonster himself. :P But yeah Wolf_ explained it quite well: "Basically instead of distributing roms Smoke is switching to a 100% legal program that simply renames and organizes roms how he would set them up. It does this by recognizing hashes (think little built in id numbers every file has) so as long as the id says the contents of the file match what he is looking for it will make sure the file gets named and moved properly regardless of what name it has, and even if it has the same name as something in his packs if the hash (once again think id number) doesn't match it won't move that file incorrectly, which makes it obvious if you have the wrong file.

    For the vast majority of a pack just downloading the "goodroms" or "no intro" version would set things up as you would want but the issue is that (imo and probably many others as well) one of the most amazing appeals of the packs is that it includes a very detailed database of pre-patched, pre-translated, hacked, and homebrew games (as well as tools like the 240p test suite and the everdrive/analogue system files) which would require anyone wanting to build the list from scratch to track down and do all of that themselves. Luckily however this means that his lists will never be taken down and vanish from the internet, or that he would get in potentially life ruining trouble for just being a genuinely awesome guy and as long as the lists are around if any single fan of them feels up to it they can make the complete packs available to everyone and if anyone gets a take down notice they can just pass the baton.

     

    Right now for example someone has already uploaded them on an archiving site which I won't name in this thread (but has been named in Smoke's thread on epforums).

     

    tl;dr: I really hope everyone can see how amazing it is that the Smokemonster packs are now preserved forever in a completely legal way and if anyone wants to download them the only thing that has ultimately changed is where they are located. Please don't be distasteful and insist that the man that has given literal hundreds of hours to researching and archiving these lists should host them himself and put himself at risk when he has already done so much for everyone."
