A few days ago, my Super Retro Trio arrived in the mail, and I've been playing with it.
The system's a pretty good piece of kit, but there were some small issues.
First off, all the cartridge ports are astoundingly filthy. There's this weird, oily black grime deep in all three ports that have to be resolved for proper function. Seriously, in the Genesis port, I couldn't use the lock-on feature for Sonic and Knuckles until this was resolved, and many NES games just wouldn't run on first try, or at all.
To clean the ports, you can either use the original systems' cleaning kits if those around, or you can use a game cartridge as a cleaning kit instead. You'll want to make sure to fully clean the game you intend to use for the purpose before beginning. Once done, it's a two-step process. First, insert and remove the game five times, clean the connectors with alcohol-soaked Q-tips, and then repeat until the black gunk you're cleaning off with the Q-tips is not as jarringly black as when you started. The cartridges will have a far, FAR tighter grip as a result, which leads me to believe that this was meant as some form of lubricant, and you'll likely have to do this for a half hour on each port the first time you go, and you'll still have to Q-tip the games after use. I might just make cleaning these ports a weekly thing for a while, see if I can't really make a dent in the remnants of that junk.
Also, the insides of the control pads have a similar issue. Upon taking one of the controllers apart, I noticed that both the boards and the pads had quite a bit of grime as well. Cleaning those is done with Q-tips and alcohol as well, though it'll likely take a long ass time for the boards, as it's layered pretty thick. Thankfully, the rubber pads were easier to clean, but they weren't of the highest quality either. I'm probably going to get some new SNES rubber pads, as the shell is designed just like the OEM controller, and the replacements should fit right in. However, even with the stock rubber pads, the controllers will feel great after they've been cleaned.
Lastly, the reset button. I had to press it a ton of times to get it to work reliably. I can only assume that they're using the same shitty lubricant as the ports, meaning I might have to take it apart and wash the button and spring.
Once all that's done, you have what is a pretty damn nice system. Like I said, once the ports are clean, it fully supports the lock-in feature of Sonic and Knuckles, and all the other Genesis games I've tried so far have had no issues. The SNES is equally impressive. While I don't have the Megaman X games to try out, I can play Super Mario RPG (made in Japan version) and Earthbound with no issues whatsoever, which impressed the fuck out of me.
The ONE issue I have is the NES portion. While it's mostly just as great as the other two, the standard Castlevania III and Dragon Warrior I incompatibility persists, and while Dragon Warrior III runs, the sound is absolutely atrocious. The sound for Crystalis is also mangled. While I don't have Journey to Silius, I can only assume that also has issues. Thankfully, these issues can likely be addressed through modding, and I look forward to seeing what Satoshi Matrix and other modders do to address the issue.
While the OEM controllers have an SNES layout, it's important to remember that they connect to the GENESIS controller ports, so they can't be used in an actual SNES the way the Retro Duo controllers can. I sent my Genesis off to get repaired, so I can't say with 100% clarity whether the controllers will work in an actual Genesis, but I imagine they would. If you'd rather go original, though, you can switch between Genesis and SNES/NES with a flick of a switch. It's important to remember that, while the Genesis port can play all three systems (playing SNES with a Genesis pad sucks, BTW), the SNES and NES ports cannot be used to play games other than those originally intended for those pads.
The button layout when playing NES and Genesis games on the SR3 controller takes getting used to. For NES games, NES B maps to Y and NES A maps to B. For Genesis, Genesis ABC map to buttons YBA, while Genesis XYZ map to buttons LXR. It takes some getting used to, and you WILL likely have to go into the options screen for the Genesis Street Fighter games, but after a while, it'll become second nature.
Lastly, the video quality. It's only Composite or S-Video, but the quality is pretty damned good for those connections. No jail bars, and the NES portion isn't over-saturated the way it was with the Retro Duo.
Overall, the Super Retro Trio is a fine bit of kit, and worth a place in any gamer's library. Be warned, however, that it's going to take a bit of elbow grease to get the most out of the system.
Oh, and the smell of plastic is strong with this one.
