Would a cost-reduced NT Mini be redundant in a market with the AVS? How many people have chosen to buy that instead of waiting for Analogue to come out with a hypothetical cheaper NT? I did and I am 100% happy with it. I do understand where RandomRonn is coming from. I never expected additional cores for the Super NT, but I admit I'm disappointed it never happened.

I bought the AVS as well and it's awesome. No jailbreak but I got a powerpak and everdrive.

Anybody who wants more cores, just get a MiSTer. There is no competition on the number of cores it can run.

 

I know Kevtris' cores are excellent, but if you want more systems at no extra cost there are other platforms where that is provided willingly.

 

Disclaimer: if you feel burned by the lack of cores, I bought an original NT... same price as the NT mini, but no cores. At least you paid less for your system :)

I think I'll wait for the next kevtris production.

Nothing bad with MiSTer, just that I like the turnkey solutions kevtris is pumping out, they also look good.

Eventually when the MiSTer2 comes around I'll look at it, personally I am not into any 8bit computers or Amiga/AtariST so the allure would be mainly on those Arcade cores .... will see.

I cannot remember in the last 10 years, a console or video game item that is at the level of allurement that the NT Mini has reached. To compare it to my childhood it reminds me of what it was like to own a Michael Jordan rookie card - unfortunately I never owned one of those, but I do own the video game equivalent - Analogue NT Mini.

 

I know you folks want all these cores on the Super NT & Mega SG, but if you get them Im afraid I wont look on eBay and see someone selling a NT Mini for $1800-$2200. With that, I always feel assured in case of a global economic meltdown or zombie apocalypse, that I could sell the NT Mini to feed my family for at least 6 months. I have five children, so dont ruin my nest-egg by coring-up those other consoles. Oh wait, the SG has 4 cores - were doomed, were all doomed I tell ya.

 

Just joking - I hope you all get what you wish. Im just grateful to be able to own all three systems and thankful for the work Kevtris and others have put in.

I tried Castlevania Bloodlines with the JB, I dont know but the last stage (stage 6) seems corrupt.

Seems like the parallax layers are a huge mess... like tearing.

 

Someone knows whats going on?

Can you post a picture? That stage is supposed to literally tear apart once you get inside the castle.

This.. The MISTer is awesome and supports a ton of game systems, computers and arcade roms. It is an extremely powerful FPGA with updates daily. They are working on CD streaming for multiple cores already.

 

That being said, the Mega SG is unbelievable! If you want a ton of cores that work terrific then MISTer.

Any plans for Mega Sg to support Astrocade and Intellivision?

Still waiting for the intellivision core on the nt mini. By the way, the nt mini supports or planned to support original intellivision and coleco vision controllers.

 

I didn't think Kevtris had done astrocade. There is an open source astrocade fpga. Astrocade emulation might be limited on the mega sg because of the analog control.

There's this unlicensed "Penguin Adventure" for SMS:

http://www.smspower.org/forums/download.php?id=2759

 

It's supposed to use SG1000 video mode, apparently. Works on emulators but not on the JB firmware with the SMS/SG1000 core. Any ideas? I specially love this game.

 

From Page 5 of the PDF manual accompanying the jailbreak firmware :

The Analogue Mega Sg is a amazing product. I love mine so much. Even more so then the Super Nt. I would like the"Sega Love" to continue. Any chance of the Sega Saturn?

If you would have told my child-self at the age of 12 & 14 (89 and 91 - Genesis & SNES release) that one day Id have both systems in their current format Super NT & Mega SG, I would have NEVER believed it. I still own every single cart I bought for my ColecoVision, NES, and SNES - I was a late adopter of the Genesis and 32x.

 

I need to locate a good Model 2 Sega CD to complete my collection.

 

The Sega Saturn was the console that killed my confidence in Sega. Not because it was a bad console because it wasnt IMO at the time. But Ill never forget standing in a magazine section as I did so many times at a grocery store reading an EGM (or another gaming mag) not long after I had bought the Saturn and reading that Sega was discontinuing support, and it made me very frustrated.

 

Yet I bought the Dreamcast on release day and still think of it as one of the best consoles Ive ever owned - unfortunately I didnt trust Sega much at that point.

I feel like Sega CD prices are skyrocketing currently. I have a model 2 but wanted to pick up a model 1 and they are going for like $300+. I am not sure if this is because of the Mega SG or if they've always been priced like that. Even the model 2 in decent condition are like $200.

I think NES has too many pins compared to snes, even if ten of them (aside from the audio mod) are unused.

 

The SNES has more pins than the Famicom does, and more than ten pins on the NES aren't required, though I'm not sure how many pins on the SNt cartridge bus are effectively programmable (like the audio and power pins are probably not). From the NES, you can eliminate all the expansion pins, one of the two ground pins (can be ganged), you can get rid of the four CIC pins, I think ROMSEL can be generated on the adapter from the A15 and M2 pins, I think PPU /A13 is just the inversion of PPU A13.... There are also a few other pins that select things where you could potentially just dedicate one SNES pin for communicating several such states over a single pin using a communication protocol from the adapter.

 

The way I see it, that means there are at least 17 pins on the NES slot that can be eliminated (or routed/generated by the adapter)? If we disregard +5v and GND, you've got 53 pins that need to go to actual functional pins on the SNES, and the SNES has 62 pins, of which 6 pins are doing power or analog signals... So you need to fit 53 NES pins into 54 SNES pins... I think it works out?

 

I'd be interested in hearing Kevin's opinion on the matter (as to if there are enough pins) regardless of if it's something he or Analogue would ever do. Like if he could definitively say "It's impossible, not enough SNt pins are programmable", then that'd end the debate right quick.

I removed 15 pins that weren’t needed from a Blinking Light Win to reduced the insertion/removal force and make it functionally identical to a top loader NES-101, which was the stated goal on the Arcade Works/BLW website/Kickstarter. One of them was the CPU clock pin, which isn’t even connected to anything on an NES-101 (“NC”). Only thing I know of that uses it is Kevtris’ CopyNES.

 

No AUX pins, no CPU CLK pin, no CIC pins (BLW bypasses the CIC), and no Expansion Audio pins (Hi-Def NES replicates internally). Reduced the pin count by 21% with significantly-reduced insertion/removal force. Worked great.

So this has probably been answered before but...

When I play PAL games on my Mega SG am I playing them at the correct speed?

 

Also

Same question but with the Nt Mini and Super Nt..

With auto detect region unchecked:

 

If you set it to NTSC games will play at 60hz. If you set it to PAL games will play at 50hz. You should match the resolution setting to avoid judder i.e. PAL-1080p50, NTSC-1080p60.

 

As to the correct speed thats a more complicated issue. Many games were not optimised to account for the speed differences so play slower on PAL systems and even have slower sound so setting these to NTSC can be considered correct.

 

Some games are fully PAL optimised so leaving these on PAL is correct. Set to NTSC they run too fast or glitchy.

 

Most PAL exclusives should probably be run at 50hz but its not always easy to tell and they often run fine at 60hz

 

Some games are partially optimised i.e. the sound plays correctly but the gameplay is slow. These will be neither correct at 50hz or 60hz.

 

Its a nightmare tbh

So basically I should just try not to think about it too much and just try to enjoy the PAL games I want to play?

 

I honestly havent noticed any that seemed off but have been curious since I got my Nt Mini.

 

Thanks!

Where can you report bugs? I noticed the buttons are swapped in the SG-1000 core and I expect the same for the SMS core. Notice if you play Loadrunner and try to press a button to dig a hole to the right - you use the left button and vice-versa. Makes it near impossible and I noticed the jump button wrong on other games.
