6502.org

Hi all.

I created this BASIC compiler originally for Z80 machines, however, I was intrigued by the fact that there are consoles with TMS9918 video processors, but 6502 processor!

In this case I decided to target the Vtech Creativision (also known as Dick Smith's Wizzard).

Of course, re-coding a whole Z80 compiler to support 6502 was pretty an achievement! Also rewriting the whole library.

CVBasic v0.6.0 is pretty complete, and all the example programs should compile just fine for Creativision. (just use the --creativision switch)

There are several examples and minigames included.

The Creativision Emulator is available from https://sourceforge.net/projects/creativisionemulator/

I've enlisted the help of some people to test in real hardware, but in the meanwhile, enjoy it!

P.S: The full manual for the compiler is included, there is also my book Programming Games for Colecovision that fully applies to the Creativision port.

P.S.2: The source code for the compiler is available at https://github.com/nanochess/cvbasic

Looks interesting! (I experienced mild disorientation that gasm80 now also supports 6502 but that's fine!)

I'm glad you like it.

I needed a certain set of assembler features to support CVBasic, so it was easier to make gasm80 to support 6502. An option could be making gasm02 but the 6502 instruction set is pretty small so it fits perfectly in gasm80.

I see there are several homebrew computers based on 6502 and using TMS9918, it shouldn't be too difficult for users to make adaptations in the source code of CVBasic.
