I love this console, but know what you are buying. This clone console uses SoC (System On a Chip) architecture. This means it tries to come close to mimicking real hardware via hardware and not through software emulation like the Retron 5. The negative aspect of this means there is no way for you to save game states internally or to an SD card. If the game cart provides a means of saving, you can of course still use that feature. No save states and no SD card slot are the biggest negatives practically about this console. If these are what you really want, you need to look at the Retron 5 for these features. The fact that the SRT3+ is NOT an FPGA console will also be considered a negative by some, but in my opinion that is silly. An FPGA console can cost $600 and up. While FPGA is certainly superior, at some point you have to ask yourself what is my real ROI (return on investment). If you have the funds and you want the best, FPGA is the way to go and MiSTer is the place to start.On the positive side and as I just indicated, the Super Retro Trio Plus HD, uses SoC technology which is far more economical than FPGA. It does, however, try to mimic real hardware. Will it play "just about everything" NES, SNES, and Genesis? Yes. Will it play everything absolutely flawlessly. No. Compared to an original or FPGA console, the sound's pitch on certain games might be slightly off or the music's rhythm might be off a bit. Some colors may appear a bit muddy compared to on an original console. However, in some cases the images might actually look better or brighter. If you've never played a certain game before or you have, but you're you're not comparing it side by side with an original console, you'd likely never notice the difference and be quite happy playing the game(s). I know I am. I've just thought of another caveat: If you are thinking about buying this to play Game Boy games with the Super Game Boy adapter, you may wish to rethink that. The tests I've seen show that it will play the games, but the sound is borderline terrible. YMMV, but I can't recommend it personally. Do more research before buying it to play Game Boy games.Other benefits:*Unlike software emulation, the games load just as fast as on original equipment.*There is "no lag" when using the controllers -- important for SCHMUP players.*The provided controllers are decent for playing NES and SNES, but unfortunately, you have to use a bumper button for your C button when playing Genesis games. I use original Genesis or modern replacements for playing Genesis games on this console.*The updated console I bought has the new 4:3/16:9 aspect ratio switch. But be careful when buying from another seller. The sku numbers are the same and old inventory still has consoles without the Aspect Ratio switch packaged in the very same box.*With the appropriate modern adapter, you can play Sega Master System games on this console. You just can't use the original Powerbase Converter. I have also read that the Rondo Products Power Base Mini FM is incompatible on this console, but I have not yet been able to test this for myself.*Will work with all-in-one Genesis and SNES multi-carts or those with SD cards. I'm sure there will likely be some exceptions, but I've seen Mega Everdrive and SD2SNES work on this console.*Provides Composite (RCA) jacks and HDMI out.Tips: Because this console is lightweight and slots can be tight, remember the R&R of game carts requires finesse rather than brute strength. You may need to slightly angle the carts into the slot on one side and then the next until it goes in. Some PCBs are thicker than others and can be challenging. The easiest removal is also performed similarly but by pulling on one end slightly and then the next. It will come right out. I would not recommend this console for children who are careless or like to throw things about. But then I wouldn't have recommended the original consoles for such abuse either. :-)) Just remember Finesse = Success but Frustration = Broken.All old retro game carts have contacts/pins that get oxidized. These contacts should be routinely cleaned (depending on the environment every 6 months or so) with a q-tip and 91% isopropyl alcohol. 1-UP cards are also great. Keep the cart pointing down; so you are not getting fluid and debris down into the cart. Let it dry first before insertion. Never buy an old cart and directly place it in your console. Doing so risks introducing contaminants into the slots on your SRT+. Clean the contacts first. Failure to clean contacts is the primary reason for the failure of game carts to play properly on any console and many people today apparently don't know this.Use the factory provided power supply, which is rated at 5 volts, 1 amp. Plug it into a surge protector. Voltage spikes are a problem for these consoles as they lack more expensive voltage regulation. Anything other than a 5 volt power supply will render the console a paper weight. You can, however, use a 5 volt adapter that supplies up to 3.5 amps because the console will only draw the amperage it needs. It's the voltage and/or using less than 1 amp PS that will kill the console. Also, the manual recommends disconnecting the power supply from the console when not in use.I have tried to go into rather lengthy detail because routinely someone will criticize this console or other modern lightweight retro consoles that use carts with the same uninformed complaints: Games don't play; too lightweight, R&R of carts too hard; console stopped working (i.e. unprotected circuit or using the wrong power supply,) kids broke the console and even failing to read the manual. It's always the console's fault. Let me ask a question: If someone unknowingly cracked a solder joint on the printed circuit board because he/she was trying to gorilla the game cart into the slot, is that really the fault of the console or is it operator error? In 1991 the SNES console cost $199. Today that equals $459. Do we really expect the same amount of durability and quality for a console that plays not one but multi-console games for a fraction of that expensive price? Perhaps there are those who do. I don't.I think this console for the price is a fantastic value. For some the price is a paltry sum and for others it will be a sacrifice even at its relatively low investment compared to more expensive options. With this in mind I say to all, respect your equipment. Not everything is truly plug and play. Read the manual and then read it again. Read reviews. Learn from others. If you're new to retro-gaming, watch online videos for various tips about your specific console. As I've indicated this console is not child proof and in some cases not even adult proof. All I can say is that unless your equipment is truly defective (which does happen), it should take care of you, if you properly take care of it.Finally, who is the SRT3+ best suited for?1. You're just getting into or back into retro-gaming and you want to be able to play your old games or some of the most popular 8 and 16 bit games ever made.2. You have original console(s) and you'd like to preserve it/them by playing your games on this newer and less expensive multi-console.The Retro-Bit Super Retro Trio Plus HD at this price is certainly the ticket for retro-gaming and may be the only console some people will ever need. If your expectations are realistic and it meets what you're looking for, I highly recommend the SRT+.
