Yes! I've used Petit Computer 2 a lot, but then I switched to SmileBASIC. It started out a bit confusing, but everything became very easy. SmileBASIC is MUCH MORE easier then Petit Computer 2 with EVERYTHING. Trust me, SmileBASIC is worth getting, and it is the best replacement of Petit Computer 2!
But, the only way to transfer files from Petit Computer 2 to SmileBASIC is with
A. PetitModem
B. Copying everything line-by-line to SmileBASIC
C. Find a program created by a user that can transfer from Petit Computer to SmileBASIC OR Read QR Codes
Petit Computer programs that use anything beyond the most basic features will NOT work in SmileBASIC. Quite a few things are different so you need a complete rewrite.
