This handy guide to the 6502 family of processors makes a great pocket reference for any retro assembly programmer.
It's a reference to the over 250 instructions (ha!) with all cycle times and lengths. You'll never need to open a book again!
Seriously though, programming retro systems is a labor of love and so is this app. I'm planning a lot of updates to go well beyond just the processor data. I hope you will give it a try.
IMPORTANT NOTE (2013-08-08) : I will have a new version available shortly that adds CPU filtering. At that time, I will set the price back to free. I like to play with the price. If you want the app for free, check back in a few days. If you can't wait, then by all means feel free to help the cause. Cheers!
What's New in Version 1.1
- By popular demand, CPU filtering on the Instruction Reference
- changed Plain UI style a bit
Almost there, but not quite
A great concept and a nice layout, but needs more work. Not all instructions are fully documented yet. I'd use this app a lot more if it were complete. That's all that's keeping it away from a 5-star rating to me.
Also would like to see a way to look an instruction up by its numeric value.
Really hope to see an update soon!
Perfect pocket reference for 65xx programmers!
Love this! Great job. I like the filter feature. Very handy tool.
Very nice app, but still not every instruction is detailed.
