Commander X16

At the moment the condtion at the 'loop-part' is not yet implemented I'll add it to the list.

It supports most of the 65c02 instruction set. Instructions that are not available havent been needed for nxtBasic to function, but can be added if needed.

Did this make it in to 1.0 and I missed the documentation on it?

No, it's still on the todo-list

A first rudimentary version of something that resembles Tempest. Written and compiled with nxtBasic.

Try It Now!

This is a more optimized, yet still readable version. .org $080D .segment "STARTUP" .segment "INIT" .segment "ONCE" .segment "CODE" jmp start source: .asciiz "hello!" ;last byte will be $00 source_end: destination: .res (source_end-source) ;reserves ...

About a year ago I found myself in exactly the same position as you. Assembly somehow felt like another world entirely. Now, a year in, I’ve developed complicated and large programs in assembly for x16 of which the biggest achievements are XFM (Norton commander style file manager) and nxtBASIC (basi...

It depends on what you want to achieve. If you just want to wait for the vblank you can just use the assembly opcode: wai (https://github.com/X16Community/x16-docs/blob/master/X16%20Reference%20-%20Appendix%20C%20-%2065C02%20Processor.md#wai) If you want to execute a piece of code on each vblank you...

Thanks for your suggestion. I've put it on the list

The documentation is up to date. If you're missing something or something seems wrong, please let me know ;-) All of the above is supported in nxtBasic. So these will all work: A=1: B=2: C=3: GOSUB SomeLabel: Z=Q: PRINT "WOW!" IF SomeExpression = True THEN PRINT "YAY!!" IF SomeEx...

nxtBasic 1.0 has just been released. Whats new? - Bug fixes LCASE/UCASE now also change the case of extended chars in an ISO charset Automatic run command wasn't working correctly without the -startin x16emu param. - New: OVAL-function to draw circles and ovals. - Improved: All sprite function have ...
