The MiSTer just updated their core so my games play like original hardware. So, for now: MiSTer 1 Mega SG 0
The neat thing is both systems are FPGA so it's just a matter of who gets updates and enhancements more often.
do you have a ROM or something I can test out? also, it could be the YM3438 busy behavior checkbox might change things. If not I will look into it. This is the first I heard of this problem.

and again relativism won't get you anywhere.
I could not reproduce the sms tearing during scrolling in games. I set up a 1 pixel/frame horizontal scroll and saw no tearing. what game(s) did you see it in? also if you feel so strongly about mister, there is a dedicated mister thread.

not to toot my own horn too loudly, 📯 but the mega SG can play game gear game cartridges on a TV using the game gear adapter.

Will it act like the old Mini in that it stays in a kind of standby mode to power the controller port so you can start it with a controller, or will it function like the Super Nt and Mega Sg and require a physical power on? Hoping for the latter, but wanted to know nonetheless.
yes this one works the same way.

9 hours ago, jamon1567 said:Question for Kev. I noticed while I was watching the video Analogue put out that outlined the new features on the Noir and noticed there was an option to enable dejitter. The current Nt Mini and the Super Nt through the DAC both have the jitter issue on my Ikegami HTM monitor(their multiformat line, but I also think this may be an issue on some of the multiformat JVC monitors as well), so this is a welcome feature. However, I was wondering if this fix was going to find it's way into the Super Nt firmware as well since it too suffers from this problem if using the DAC?
yeah I was going to add it in on the snt at some point

the super gameboy 2 uses its own crystal and doesn't have any use for the 21MHz clock coming from the system, so the GB cart will get the proper 2^22MHz signal it expects. I think the RTCs on the carts have their own 32KHz crystals anyways, and will always run on that regardless of what clock you're driving into the GB itself. Thus, using the RTC to check the system clock accuracy won't produce meaningful results I wouldn't think.

If Analogue was providing regular firmware updates for their products there wouldn’t be so much complaining. Instead what we see is maybe a year or so of support then they move on the next product and act like their previous products don’t even exist. This creates frustration for those of us who paid good money for them.
it's not that I am "laughing at ignoring the thread lol" but I work many hours every single day on this stuff. I don't ignore complaints, but there's not a lot I can say about internal operations so I don't say anything.

20 minutes ago, ErebusMaligan said:Ah, OK. Thanks for the info.
Just to note:
I was already on boot to menu, and it still has this problem.
Pressing reset works for normal GG carts, but does not work if the cart is a GG Everdrive.
this could be because the gg everdrive starts up in SMS mode maybe.

1 hour ago, ErebusMaligan said:So I just got time to mess with my replacement GG cart adapter, and I noticed it isn't loading the settings associated with the GG core, it is still set as Genesis mode when running the cartridge. I wasn't sure if this is the expected behavior or if it was supposed to load the core settings.
I went back and read this topic around the late 500s pages and there was at least one post of someone saying it was supposed to know which core to use based on the adapter being inserted. I went back and tested my SMS card adapter, and it too only loads the genesis settings. The games seem to play fine in either case, but the video settings and core settings are displaying the genesis options. I am running the JB 7.7 fw.
I'm just trying to figure out if this is the normal behavior, or if something is amiss with my setup, and what that could be.
yeah this is a known issue. press reset or change settings to "boot to menu" to fix it until an update is released.

5 hours ago, 1001lives said:I'm sorry but an FPGA or clone console will never be worth 900 dollars.
$200 isn't bad but RetroUSB's AVS sits around $180 and I think that's a much more fair price. You can't tell the difference between 720p NES games and 1080p NES games on a 4K tv.
people are paying it all day long on ebay. right now there's dozens of auctions selling the nt mini. remember too that it's a lot more than NES, does 1080p, and there's 17 other cores to play with. the nt mini has the best 2600 FPGA core, and some really obscure things (gamate, supervision) that aren't available elsewhere. the AVS is fine if you want bare bones. but if you want some meat on dem bones, you move on up to the nt mini.
if it wasn't worth the price, it wouldn't have sold out so fast, and then go for double the price on ebay within minutes.

Why they are they opening it up for orders? They have to still ship it to all the suckers that paid them. The thing's almost a whole year late at this point. Maybe they want to rob peter to pay paul, kind of like a videogame pyramid scheme. They need money to fulfill current orders, so they will use the money from new orders to build the stuff for old orders. They've wasted an entire year's worth of money without shipping anything, so that cash has to come from somewhere. I guess shipping out a few "beta units" will show that yes, it does theoretically exist, so place those orders now!

5 hours ago, Papy said:It was not an evil ploy to sell more games, it was just to adjust to gamers.
OK, I will explain what I mean...
Trigger warning : this will include some controversial political ideas. So anyone who is easily offended should avoid reading this.
Actually I think the answer is much, much simpler. ROM got cheap. Games got a lot more linear simply because now you weren't restricted to a simpler "Arcade" style high score game because you had room to introduce new game elements like stories, characters, places, maps, etc. Add on battery RAM or similar technology and now you could save progress, too. I don't think it's such a bad thing that a bunch of games ended up being like this, and in fact I welcomed it. Metroid was the first time I really felt like I accomplished something when I finally beat it, spending weeks mapping it out and exploring every nook and cranny.
Even though I thoroughly beat it, I enjoyed playing it over and over, trying to get all the items, or beat my previous time, or whatnot. It's kind of like reading a book. You are allowed to re-read a book you really enjoy. The Fun Police(tm) aren't going to come and tell you you can't.
I actually tend to prefer games with a defined endpoint, so you can beat it, put it down, and then pick it back up and try to beat it again, but faster or getting more items, finding things you missed the first time, etc. The extreme end of this is speed running. I seriously doubt giving a game a defined end point is done to sell more games- it gives the player a sense of accomplishment which was always missing for me on arcade style games. Back in the day, Adventure was my favorite 2600 game (on game 3 of course) I think because you could win and then try again.
Being able to nose around in every corner and crevice of a game like Zelda or Metroid is intensely fun and rewarding when you're a teenager, or at least it sure seemed that way when I was one. Truly mastering the game and spanking it hard when you finally get it all figured out.

4 hours ago, Papy said:In reality, apart from physical constraints (playing with a mouse/keyboard while relaxing on a couch is kind of difficult), controllers don't matter if the game is designed for that controller. This is why people can play FPS with a gamepad, even if a mouse is clearly faster and more precise. Pseudo-hardcore gamers who are used to gamepads might complain a bit about a new controller design, but most of them will learn.
Well there's a reason why most FPS games don't allow mixing of PC and console gamers- the PC players just absolutely clobber the console ones because they tend to use mouse+keyboard instead of the console game controller. The mouse is by far more precise for aiming and being able to bind keys on the PC just finishes the job. Personally, after playing fps games using the keyboard+mouse and trying to play a similar game on a friend's xbox was pretty limiting feeling. why can't I turn faster dammit! why won't my aim point change faster! The lack of precision was pretty striking after using the mouse for so long. It reminded me of how back in the 90's I would use the keyboard only to play quake, and got trounced by all the mouse+keyboard players. Learning to use the mouse opened up a whole new world.

The in-app purchases can be spread over days, weeks, or months too so that nickel and dimeing doesn't seem so bad to the average user I suspect vs. the big lump sum of $60 or whatever for your average AAA title. "Well it's only 99 cents for this doodad! that's not bad!" times 50 or 60 over the course of 3 months. I totally get why they have it, but that doesn't mean I have to like it. It definitely is killing a lot of modern gaming for sure.
I was bemused when I watched my friend playing the latest ass-assins creed, which added microtransactions. booooo. I hope the new elder scrolls game doesn't turn into a microtransaction crapfest but I bet it will.

I am guessing for the $5-10 per game, there won't be enough development budget per title to make them really long and in depth like the original EWJ titles were. So a collection of the EWJ style minigames might be what it ends up being. The development budget is what's going to dictate the kind of games we'll see on the system. Only so much game can be created with the budget.

Has there been any theories on the exact SOC that is going to be used on the Amico? I have a few theories and figured I might as well post 'em.
My first guess is the Allwinner A83T. This appears to be an extremely close fit to the information released so far:
* 2GB Maximum RAM
* 1.8MHz, 8 CPU cores
* Raw NAND flash support (for the 16GB of onboard flash)
* Ethernet, Wifi, USB
* HDMI port
* Can run Android/Linux
The A83T is available on the "Banana Pi" board which is an obvious take on the "Raspberry Pi".
Banana Pi:
http://www.banana-pi.org/m3.html
Quickie data sheet with some basic specs and such:
https://github.com/allwinner-zh/documents/blob/master/A83T/A83T_Datasheet_v1.3_20150510.pdf
Info on the included GPU:
https://www.imgtec.com/blog/the-powervr-sgx544mp-a-modern-gpu-for-todays-leading-platforms/
The second guess is the Qualcomm SDM450. It isn't as close of a fit but still fairly similar.
* Maximum RAM is not specified
* 1.8MHz, 8 CPU cores
* Ethernet, Wifi, USB
* Not sure if it has HDMI
* Can run Android/Linux
This one is really designed for cell phones and tablets, so it has things like a cellular radio that the Amico most likely won't use.
Qualcomm's page on it:
https://www.qualcomm.com/products/snapdragon-450-mobile-platform
So I'm leaning towards the A83T, especially since the dev team could just use that Banana Pi dev board as their base and plug everything they require into it. That'd make development a snap. The Banana Pi board costs $59.99 on amazon. Throw on a USB hub for the multiple devices they want to include (multiple USB ports, RFID), and the board has everything else the Amico requires by the looks of it- HDMI out, ethernet, wifi and bluetooth. It also has 8GB of NAND flash (the Amico will have 16GB but this is an easy upgrade when transitioning to final hardware), The 2GB of RAM is already on the board as well. It's almost a tailor-made Amico board as-is. There's some general purpose IO and probably I^2C/SPI which would be quite easy to connect to the RGB LEDs on the base unit. It comes running Android by the looks of it, and going by the Night Stalker video, they are running the games on Android (you can see the Android buttons pop up at the end on the screen at the bottom). They could be running it stock just to get development rolling.
It will be interesting to look back on this when hardware info is eventually released.

odd/even line at 60-ish hz with the other half black/dark-grey as it may be?
Does it just cut luminosity (maybe you compensate for it) or can one see the "original flicker"?
it's interlaced like the genesis does it, with the same timing

38 minutes ago, jamon1567 said:So in theory, the DAC shouldn't care if the USB power out isn't connected to and powering anything? I was thinking about ordering another switch off Amazon that uses micro usb as it's power plug just to test.
yeah the DAC doesn't care what powers it, so long as it's 5V. It does not have to have anything connected to USB out- that is there so you can daisy chain power off one adapter and not need two.
-
5 minutes ago, jamon1567 said:Kev, the instructions with the DAC say that the firmware can be updated. Is there any chance of this thing working with HDMI switches in the future? Would it be possible for this to work with a switch that was powered by USB? I noticed that when I hooked it up to my switch the LED on it was a steady white when the USB out was not hooked into anything. When I hooked it up to my console though it was blue and it worked of course. If the power out was hooked up into a switch for instance, would it work?
The DAC uses non-standard HDMI signaling so the switch probably doesn't like it.

3 hours ago, Andromeda Stardust said:Skyrim Nintendo Switch -> HDMI converter -> composite RF modulator -> Rabbit ears -> GG tuner antenna -> adapter -> GB pocket.
Yay for 90s technology: 144p portable gaming!
As it ships, the adapter needs some parts added to use the RF input and/or get audio out of the tuner. These were not added since the tuner isn't officially supported. The composite video input WILL work though on the adapter as it ships.
I used a dual RCA to 1/8" stereo cable to feed the audio/video into the tuner, and plugged it straight into my NES. For audio, a few resistors/caps and an op-amp are required. This matches the high impedance output of the tuner to the low impedance input of the Genesis.
For RF use, a boost regulator is required; this boosts the 5V up to around 35V(!) to run the tuner. Later I will post a list of the required parts for each.

7 hours ago, MrBeefy said:Thanks for sharing! I don't own any of those as all my original stuff is still kicking. I was considering getting the GB one though.
What do you think is the biggest hurdle in bringing something to market?
Getting it done! That's so far the biggest thing I think. Getting it to the finish line is pretty difficult I think. Production requires money and connections though, which could be considered difficult also. But if you have a finished product ready to go and can demonstrate such, getting funding is a lot easier. It is relatively easy to get 90% of the way done, that last 10% is the killer.

Very cool. Congrats on your success! I actually have Genesis one that I purchased at a convention (I forget which one it was?) Not sure if it was from you directly... so we may have met.
It's amazing that you are pretty much a one man show, but I hope you can appreciate and understand the vast differences of what we are doing and although there may be some similarities... it's a very different project in many ways.
Continued success to you.
Have you ever thought about doing a new portable Genesis or SNES? Like the Nomad back in the day? That would be amazing.
I have never been to convention, so nope probably not met. Yeah I understand that there are differences. Thanks for the kind words!
The Pocket will run genesis and SNES cores, so it can play those things, along with the gb/gbc/gba functionality. We are allowing homebrew cores for it, so anything is possible.

1 hour ago, Kosmic Stardust said:How? 😱 Did he stuff a composite adc somewhere?
the tuner has an ADC. It outputs data in the format the LCD on the GG takes, which is... terrible. It is actually checkerboard interlaced. I played megaman 2 on the tuner and it was... rough. looool. But it's in there. So you could play skyrim on the mega sg in 160*144 pixel glory (or gory).
