Heya, first post here.
Some of you may know me from #NESdev, #GBdev, #N64dev, AssemblerGames, etc
As I have founded a company, that has developed competitor product to this, that actually has a functioning prototype with much more support; I'll add my two cents.
There's some niche market needs to these types of "in the middle" machines (meaning, these these types of systems that aren't just running roms into an emu, nor running the cart natively, thus middle). A lot of people have a nostalgic connection to the exact cartridges that they have spent many hours on, mainly because of SRAM data. Being able to continue your saved game, load up ghost data, and more, is a great thing (unless the batteries are dead).
However, I have some strong professional doubts about this "RetroBlox" console, due to the things I've learned while actually forming a business to produce my product. I'll touch on these a bit later, as I don't want to be outright attacking these guys, but so far, I don't see any feasibility within their company.
My two cents. Happy to finally be a part of AtariAge. Saying "Hello" from Hong Kong.
