Let's take some 2D Zelda for Gameboy or SNES and tweak the emulator so to run the game only if some button is pressed, but for a minimum of, say 60 frames, that is 1 second. We get simultaneous turn-based game, we get a roguelike. Don't we? Does that sound like something you would like to play?
No, we wouldn't get a roguelike. No, it doesn't sound like something I would like to play. And no, let's not do that.
I hope this post is supposed to be some kind of parody of other threads or something...
Do you actually see any reason why would it be less good than a regular roguelike?
This is a better question. I think you have to clarify what you mean by "regular." If you mean what I usually mean, i.e. "real roguelikes," games that have a certain level of feature completeness with theme and mechanics in the vein of the original examples of the genre, then I would say obviously some hacked up junk made by lobotomizing an emulator and loading a zelda rom is going to be worse than, e.g. crawl or angband. If you mean will it be better than an average 7DRL, idk, maybe.
There is! You can google it easily, exactly that: "ZeldaRL".
This all reminds me there is also turn based Pac-Man and Bomberman, orginally arcade games. They are perhaps rather boring, but with our special emulator any game could be made turn based, and I have a feeling many games would actually still preserve some of their original challenge and thus still be interesting and playable. Perhaps even more playable on mobile phones where they are otherwise really unplayable via touch-screen.
I'm surprised by the tone of your response to CaptainKraft, given the spirit of charity in which he responded to your initial post. It seems apt to refer to the emulator you propose as "special" though. You seem to have your finger on the pulse of a certain misbegotten branch of the genre in which people take their favorite 80s or 90s video game and add "RL" to the end as the name/design of their 7DRL (or worse, long term project). I mean, at that point, why not just use the LazyCat arcade emulator (written by people inspired by his forum post, natch) to convert, say, Lode Runner into Lode RunnerRL?
