For 100% compatibility you would need things like Joycon support, including things like IR camera, as well as all of the music, sounds and default images that are included.
One of those is complex given how messed up Windows and its many drivers has gotten, probably requiring hacked drivers and all of the complexities that that brings.
The other is .. well, it's copyright theft, basically, and if you're truly aiming for 100%, then that's going to be one heck of a brick wall to overcome.
You have to err on the side of caution, and if it's means creating "HTVBasic" then I would much prefer to support something like that, than something that could end up getting a C&D at any moment.
At the end of the day, BASIC is BASIC, and if you write a good language, with "(*) support for SmileBASIC programs", then that would be much appreciated by many. You might also scan through other basics, and see how many you can mangle into one. Classic 8-bits.. BBC, Commodore, Spectrum, Amstrad, etc.. You could write a perfect "all in one", with support for everything, all under one roof.
"The Ultimate BASIC"
..."FINAL BASIC"!
Just imagine if it takes off, and your language becomes supported by many developers, and ends up being taught in schools... constantly with someone else's (SmileBoom) name attached.
How would that make you feel?
I don't feel that you quite grasp the legal issues, from your uhh interactions so far, though maybe that's just me being painfully aware of them after watching this community for so long.
To be very blunt, this looks like another "Hey what if we did <x>" thread where the idea sounds okay but OP doesn't understand the magnitude of the proposal and has nothing to bring to the table.
If it's for your own experience or whatever, then the project is something you should at least start on your own, and if it's something that you want other people to, um, "help" with, they'd be better off organizing it themselves.
FWIW : I'm not saying you shouldn't do it. If anything, I think you should. But just be aware of all the legalities of "duplicating".
Over the stupidly long time that I've been online, I've seen SO many long-term projects being completely destroyed once they're unveiled and released to the public, simply because they used other people's IP.
People keep saying "Well what about Sonic Mania?" and .. yes, that's a rare success. It's a fantastic success, too!! But it IS a Rarity, and you should always assume that the opposite will happen.
In this situation, I think it's OK to do "BASIC", and even add "Smile Compatible", but not specifically do "A Smile Clone". That's where the main problems might occur.
And even if it's not CEO himself, who you've asked and he's semi-OK'd it.. .. It might be some hired Lawyer trying, noticing your project and trying to do the right thing.
You really do have to err on the edge of caution. And I'm just trying to make sure you do that before putting too much time and effort into things.
From the get-go, always assume someone will sue/C&D you, and take things from there.
So.. Yes, absolutely, go ahead and make this.
But just be wary of being "A clone", and instead consider it "An option"..
IMO> The more variants of BASIC you add, the less trouble you'll be in. You're just "Adding compatibility", not "cloning".
I think this is a great idea. Like everyone else is saying though, LEGAL. Still, it would be nice to just load up smilebasic games on a website whilst using a gamepad/kb and mouse to play them. Would allow people who dont even have a ds to access these things too.
And, you do get the rights, allow for smilebasic stuff to be uploaded from PC. No more hunching over my ds trying to type out stuff with a pint sized pen.
