At school I'm learning BASIC (not visual basic).
We have to use Macs in class but I only own windows.. We use FutureBASIC.
I've searched around and haven't been able to find a windows equivalent. Only Visual Studio which is for Visual Basic not Basic.
So does anyone know of any programs that could help me?
A good emulator will handle CPU specific instructions by translating them into the appropriate alternative instruction or collection of instructions to achieve the same functionality.
As for specific commands, I've not used basic for 15 years and even then it was on a BBC machine. You'll want to stick to core functions that are shared between the two. I don't know where you'd get this information.
You're much too diligent a student. Just hang out and play Nintendo
