I've updated IntyBASIC with the SELECT CASE / END SELECT statements because these are very useful, and also added export of constants to assembler (a feature requested by developers) #retro #retrogaming #intellivision github.com/nanochess/in...

Pretty surprising 🤯 btw Claude is also being used to create games in IntyBASIC. Very early, but I'm willing to see how so far this goes.

Thanks! IntyBASIC has been used to create more than one hundred of new games for the Intellivision. CVBasic is following on these tracks, supporting 14 consoles with Z80/6502 processors.

Now there are around 12 to 18 new games for Intellivision every year because IntyBASIC. And recently, I've made CVBasic for the Colecovision, and around 15 new games for Colecovision have been produced using CVBasic this last year 😉

Indeed! I discovered how so difficult is developing for Intellivision while making Princess Quest. IntyBASIC makes far easier the development of games. And my extended ECS BASIC makes justice to the Mattel ECS add-on, it becomes fun to use! 😀✌️

Princess Quest is an excellent piece of work, and has led to the Intellivision doing other surprisingly NES-like things. It makes me think CastleQuest could also work on the Intellivision. I painted the cover to an IntyBASIC compilation some years ago, seen here.

My understanding is that Oscar Toledo Gutierrez really understands the hardware, and with CVBasic and IntyBasic, he's optimized the interpreter as much as possible to avoid generating too much bulky or inefficient code. I'm less sure about its NES/MSX2 capabilities but those are interesting also.
