Virtual Machines and CPU emulation - update.
In my last update I have been ecstatic about my MOS 6502 emulator running Tiny Basic. Nice achievement, but later more rigorous testing shown my emulation still had issues. I ran few available on the internet test suites and they all passed, but still I was unable to run Enhanced Basic in my emulator.
After I established that it was not a problem with the copy of EhBasic code in my possession itself, I turned to my code to look for errors. I found and corrected few obvious issues, but still no luck.
Finally I turned back to the internet search to find a better test suite.
I found a very good one - 6502 Functional Test by Klaus Dormann.
After I ran that program, I found all issues with 6502 op-codes emulation, some of them were tricky and I am sure I would have problem finding them on my own. Therefore 6502 Functional Test by Klaus Dormann deserves huge credit in making my project going again.

I published version 2.0 on github. There are major changes, many new features and bug fixes. I believe this is a complete or nearly complete DOS/shell version, I run out of ideas what else I can add to a version that runs in text console. To move this project forward I have to move out of the shell window into the GUI world. However I have few ideas for improvements which I will outline below.

Thanks for visiting.

I recently e-mailed Mike and asked if my emulator was worthy to be added to the 6502.org's emulators section.
He agreed and it is now added.
This is when I found this topic.
I wish I checked the forum more often.
Perhaps I will try it as New Year's resolution :-)
One has got to be up to date with new hot 6502 related stuff!

Happy New Year everyone!

Glad to see your emulator catalogued! Do come back a bit more than once a year!
