The App Store, albeit an interesting idea and possibly it might make sense if the moderately active user base (and not just people who had nothing to do with Commodore in 20+ years) was not maybe 10,000 to 15,000 people world-wide but grew two magnitudes of an order larger then yes, I can see this working sensibly. Even one magnitude of an order would be a starting point when sales of individual games rise from maybe 100 to 750 copies to about 1000 to 7500 copies would be a start. We really need to get closer to the 10,000 to 75,000 copies being sold world wide and an app store that would facilitate that to make meaningful sense for not only its cost but for developers to sell copies of their game at anywhere from $2.00 to $20 a copy. Considering it will need a team of people to manage and run this app-store 24/7 and provide round the clock customer service and technical support.
If we had internet back in 1987 like we have now, the idea of an App Store would make absolute sense. It would be awesome. After 1997, the Commodore community had lost critical mass to support a meaningful commercial side. After 1997, it was all she wrote. By 2001, CMD closed it's doors on the Commodore 8 bit.
After that, Commodore community had rapidly eroded at an accelerated rate and then began to leveled out at a minimal complement of users that are dedicated.
What kind of a Commodore user would need a THEC64 Mini? You say its a toy? Yeah, so is the C64 depending on how you look at it.
If you're interested in playing the games, why not use what you already have? What? No laptop with HDMI? What the TV doesn't have a VGA connector? What, no DVI connector? What you can't buy a ~$10 VGA output to HDMI Video?
Such as on Amazon (dot) com
There is also HDMI cables you can buy.
Just so you know, C64 Forever minimum system requirement is 750 MHz PC but a single 1 Ghz single core or faster CPU is recommended especially depending on the version of Windows that you are using.
RAM: 512 MB minimum RAM but 1 GB or more recommended.
Hard Disk space needed: 200 MB free or about but more space is recommended as you build your collection of games.
You don't have a computer other than your main computer that doesn't meet these requirements ????
Virtually any Pentium 4 or later computer made in the 21st century would meet this system requirement or a Pentium III with 750 MHz or faster model. I think you got to have something more powerful than that sitting around somewhere that you can place near the TV. Worried about noise, there are solutions for that.
If they just want to play the games, they can use a PC with a real surround sound system which by the way would be louder than the fans would be. It isn't like the emulator would be hard working the PC that the sound would be negligible. I probably use more computing resource in using Google Chrome than I would be using the emulator and the only time the fans really kicks up is if I was running a modern PC game. My 1541 made more noise than the fans would be. My dot matrix printer was known to make much more noise than the fans on the computer.
That argument of fan noise is a weak one and you knew that. I think they'll be fine playing those games on their PC which more than likely has a screen bigger than a 1702 monitor and even modern LCD TVs. Hell man, PCs, Xbox One and a cluster of other game consoles are often already hooked up to the BIG SCREEN TV in many people's homes. Since the PC is usually running all the time, they'll hear the fan noise anyway (if they have a noisy fan and not replaced the fans with the stealthier double-ball bearing fans or at least clean the fans once in awhile) so why not play the games on their PC on the big screen?
They usually already have modern 5.1 or 7.1 Surround Sound systems that supports HDMI input in the first place.
