Back in my games programming days I never had a BBC micro, though I knew several people who did including one bloke who let people run their ROMs on his micro. Sneakily it made a copy of the ROM contents and saved it to disk. I remember wasting a lot of hours playing Elite on a Beeb back in 1984.
BBC BASIC for SDL 2.0 is a cross-platform implementation of the BBC BASIC programming language for Windows, Linux (x86), MacOS, Raspbian (Raspberry Pi), Android, iOS and Emscripten / WebAssembly by developer R.T. Russell. If you ever fancied writing BASIC programs and running them on a BBC Micro then you now can with this.
It is programmed in C (and I’ve added a link into the C code library) and you’ll find the multi-platform source on GitHub. A visit to the Complete BBC Games archive might also be in order!
