See the middle of reply #45 on page 2. I give my thoughts as to the "point" of the RetroN5.
As to what you said about clinging onto CRTs, there is no doubt that there is a prevailing wisdom among retro gamers that CRTs are inherently better than HDTVs for retro gaming, but I think a lot of that attitude comes from the fact that analog (composite and s-video) signals look awful on HDTVs, and that some HDTVs are ill-suited for retro gaming if they lack gaming modes.
I have an Ouya, which among other things acts as a native 1080p emulation box the same as the RetroN5 promises. Playing NES or Genesis or whatever else in 1080p on a 55" screen is pure bliss. Not only does it makes each pixel bright and crystal clear, it also removes any overscan concerns, so that every last pixel is visible on your display.
Don't get me wrong, I have a fleet of CRTs in my own home as well that I love to play my retro consoles on, but let's face it - CRTs are the pits. They take up so much damn space, are so heavy to lift, and with age bring all sorts of other problems. On top of it, with devices like the Ouya, their very purpose is being threatened.
Even when I play my retro systems via RGB SCART on my CRT, those same games look far better on my HDTV in 1080p HDMI. Directly comparing the two, there's a clear winner with HDTVs.
If the Retron5 lives up to the Ouya, it could very well make retro games look better than they ever could on a CRT.
Yeah I figured that was the case. No worries.
I doubt that the legality of roms is Hyperkin's motivation. Consider the AtGames Sega Genesis portables which are even fully licensed by Sega. Those things have build-in licensed games, and a few of them don't even have cartridge ports but instead offer to play Genesis roms directly from an SD card. I would guess that its more likely a marketing strategy on Hyperkin's part to use the carts to set up a niche to differenciate it from their competition, Retro-Bit and Yobo Gameware.
As to your complaints against clone hardware out of China, it's not so simple as that. 100% fully compatible NES/Famicom clones do not exist despite over two decades of various manufactures producing them. Early discrete clones would have PPUs with the wrong pallets and CPUs with reversed duty cycles causing bad audio. When NOACs began to take over, the quality of clones began to differ wildly. Some - like the TriStar/Super 8 are nearly perfect in all aspects while others like the Yobo FC Game Console are incredibly inaccurate. This has continued over the years and the dream of a perfect NOAC still isn't a reality.
The solution to fix that would be to design an FPGA solution, but that would drive up the cost immensely to around at least $150 for an NES only clone. Then factor in the other four systems also being FPGA based and you'll quickly realize that reverse engineered hardware that's 100% accurate is too cost prohibitive. Emulation makes far more sense, especially if it's Android based as Chinese companies are pumping out low cost android devices on a regular basis now.
I personally would rather have an FGPA based RetroN5 that costs $300, but that would have no chance of selling to the general public and causal gamers.
