Whoa whoa, slow down. First, keep in mind that everything mentioned here is based on what one person said who didn't post any proof of his claims and in fact quickly removed the claims he did make. Also, he was using beta hardware. I'm not saying that he was lying, just that there is no confirmation on anything of this, and even if there was, things could change a lot between now and whenever hyperkin decides to release this damn thing.
Second, you're directly comparing reverse engineered hardware to raw emulation. Hardware clones are incredibly dumb; they're limited at whatever flaws they were designed with, with a limited window of tinkering from the end user should they be knowledgeable in soldering and basic electronics.
Emulators on the other hand exist purely as software. The RetroN5 won't be running any of the games in hardware because it doesn't have the hardware to do that. It's not a reverse engineered hardware clone. Therefore, it has to reduce the games to roms for the emulators to run them. Interfacing with the cartridges at that point is no longer possible. Think of it like the GameBoy Player's boot disc that's only purpose is to be there upon bootup. the header check is needed so the Retron5 knows what the hell cartridge it is that it's dumping to rom.
Third, the header check against a database doesn't necessarily mean the RetorN5 won't be able to play games that don't show up in the database. For example, on Ouya, one of the SNES emulators -SuperGNES- uses the header info of snes roms to generate boxart thumbnail to make browsing for the game you want to play a less boring.
It's possible Hyperkin might have the same kind of thing in mind for the RetroN5's interface. Maybe there could be a 'history' page telling a blurb about the game and it's release data similar to have mame and coinops work.
Any game that's a fan translation or unlicensed or whatever shows up with invalid boxart data, but the games are still playable. The interface might spit out "unknown game" for games like Pier Solar or Battle Kid and still let them boot. and even if not...this is fixable in the future with firmware updates.
This IS an interesting question, no doubt. What is the point of the RetroN5? why not either stick with the original hardware on all accounts, or go with a 100% pure emulation option like the Ouya? Why do this half-and-half system?
I'm not sure I have an explanation myself as to the interest besides novel curiosity. I do admit that I am drawn to the idea of multiple in one consoles such as the crazy contraptions Bacteria has made and I'm also drawn to the concept of having convenient emulators on other devices like the PSP.
I'm also at a crossroads of sorts when it comes to how I really prefer to play my retro games. Long has it been that I've hung onto several CRTs to keep my precious retro gaming systems alive since they look awful on HDTVs, but with devices like this that aim to bridge the gap I'm hopeful the day is not too distant that I'll feel completely justified in getting rid of all but one of my heavy heavy CRTs and replace them with slim, light HDTVs.
"Need' isn't the right word.
I have hope for the RetroN5.
This brings up anther conflicting point within me. I own everything the RetroN5 will run in hardware, including the Famicom. I Also own an Ouya - an HDTV ready emulation machine that does everything the RetroN5 does and a whole lot more. The RetroN5 won't work on CRTs (at least not natively) and I already have an HDTV retro gaming solution I'm very satisfied with. Still, its the burning curiosity that drives me forward with the RetroN5. I'm really curious to know it directly compares to the original hardware and also the Ouya.
If so, it was [removed]. Do you know what he said?
