Emulate doom-teletext on browser

[GEROGIANNIS]

Hello there! ( · ⌣ · )/
I don't really know if this is possible since i don't understand how you made this , but i remember these guys called "BitShifters" that make stuff using teletext
and as you can find here their projects can be emulated using this site. Example.
)

So, im curious if this can also be used with this project to run it from a browser.
If there is anything I can do to help you, let me know.

Thanks! (っ´ω`c)♡
