Is there anything similar to SmileBasic for Raspberry pi?

Raspberry Pi is mainly coded with C, if I recall correctly. You could probably port SmileBASIC programs as long as you can find equivalent instructions in C.

@Oscar The raspberry pi is mainly programed in PYTHON but it can be programed in C,C+,etc. People use python because it can access the gprio pins.

PICO-8 is the closest thing I know about. The coding is based on Lua, so it's a bit different from SmileBASIC. I dunno if you played it, but Celeste was made for PICO-8 before it was ported to SmileBASIC...in case you were looking for an example.

There is python + pygame, and scratch if you want to code games.
