Hi all! I decided to put together a small guide to programming Creativision using CVBasic. As you maybe know, CVBasic is an integer BASIC compiler with a QBasic-alike syntax, it targets several platforms, and the 6502 in the Creativision. The first step is downloading the most recent version of CVBa...

Hi all! It is kind of hard to experiment manually with sound effect generation for the Creativision and CVBasic. So I decided to repurpose my Intellivision sound editor (you can see it at https://forums.atariage.com/topic/320358-sound-effect-editor/ ) and use the bigger screen space available in the...

Cool! Thanks!

In this game you must jump over clouds without falling down. It is a single button game. Enjoy it! P.S: Brinco means jump in...

I'm glad to know I finally made the joystick to work properly in diagonals

Amazing! Thank you very much

it is not fully documented yet, but you can access the Creativision keypad reading directly $18, $19, $1a and $1b by using PEEK(). This is because the Creativision controllers are complicated enough that it is preferred to call the BIOS to process the controller instead of writing my own subroutines...

Hi. I've added support for keypad (at least the numbers, RETN and the left arrow) to the latest version of CVBasic. With this is enough to make GORILLA.BAS to work in Creativision. You can download it from here: https://nanochess.org/archive/gorilla_multiplatform_cvbasic.zip This is a 32KB ROM that ...

Thank you very much!

Cheers, TOM:0) Thanks you so much for your help! :) I now can remove the "experimental" label from the CVBasic README. Please coul...
