There are many BASIC emulators to play with already. Lua is better though. Using tic, I am pretty sure the frame rate is 3 times faster, if not 10 times faster than BASIC. I like to fiddle with BASIC too for nostalgia.
At the end of the day, it is just outdated. It's like using visual basic to make a Windows app; nobody does that anymore for a reason: it's just not efficient.
