Thanks alot sir. For this video it is helping alot in deliverable 1

[@hamzasabih997]

Honestly helped a ton jazakallah sir for all the effort you put in for us

Good work. Text mode 80x25 with page number 0 to 7 Text mode 80x50 with page number 0 to 3 Each page have its own cursor location and colored text inside.

Imagine with this information we can make a tiny text based mini game with some character to play.
