Yes thats another plus to these all-in-one remake systems not having to swap games.
I am just hoping that the ROMs they use for the games are the actual originals and not a modernized ported version that is different. For the Atari 2600 all-in-one which I think has 40 titles, there are some differences in sound and graphics that stand out so its close to the original but different.
I noticed that Duck Hunt as well as other game titles requiring the gun controller are missing from the list of titles and thats because the original games require a CRT display in order to function properly for hit box detection. On my original NES and Yobo clone my gun wasnt working and I thought the gun was broken. Borrowed a gun controller from a friend and still not working. Held gun to the screen and still missed the ducks when back in teh day as a kid doing this was a way to get crazy scores. I then did research online and found that the way the game detects the hit box on the screen it needs the CRT after glow which LED and LCD displays dont do.
BTW, I'm pretty sure Blowing on Games is one reason why people have problems with the Original Front-Loader system. Mine still works perfectly- no less reliable than my SNES or N64, and I've never blown in any of my cartridges.
Back in the day of the mid to late 1980s it was what just about everyone did and it worked unless someone spit into the cartridge. There were even cleaning kits for the cartridges. My friend had one cleaning kit that i could have sworn was pickle juice based on its smell with a foam tipped stick to wipe down the gold contacts.
Speaking of SNES and N64 .. I still have my SNES and never ever had the contact issue with the top loading of it. I never understood why they went with the insert and push down to spring loaded pins design of the original NES. I thought maybe it was to just be different than all the other systems that were forced insertion to top of game consoles like the Atari systems and others, with Commodore 64 being in the side of keyboard etc. I miss my N64 and if they make a N64 all-in-one system I am hoping they place 007 Golden Eye on the game list of included titles. I loaned the game system to a friend and it got stolen while at his house with all my games and he never paid me for the loss or replaced the system. Ebay is just a few clicks away to replace it, but it would be at my expense and i actually dont play console games as much as I use to. The Playstation 3 that I have I pretty much gave to my daughter to have and I have the 2 other playstations before that in storage. Never bought the XBox because of the ring of death problems people were having and I cant justify paying $50-60 per game title.
I think thats probably one of the reasons why I became a PC Gamer vs Console Gamer is that games are cheaper and almost endless selection of what you can run on the computer with the right Hardware and OS combination vs a console system being locked into limited list of titles and all at a premium of serious cash unless you buy second or 3rd hand games from a rental store or gamestop trade-in's.
