I have long been interested in the question of programming using this IDE, using a computer keyboard. On most emulators work with keyboard is good, but not with VirtuaNES.
First, it is impossible to enter certain characters, such as ":", ";" and "*". Second - after my changing the font from Japanese to Russian, the rom works correctly only on VirtuaNES (other emulators giving this error:

),
which may affect the compatibility of future games written on it. Well, and thirdly - I don't have enough information on programming in this IDE, in particular using BGTOOL.
Modified Family BASIC ROM (patch):
