Think I'll make a thread this week then, explaining and showcasing some of what I've built

I'm currently implementing a processor that is heavily inspired by the 6502 and PIC18 in Minecraft. Minecraft is slow and much different from the real world, but I'm part of a community that actually competes in creating processors that outperform each other in the game. Implementing modern (or ...

Really hope formatting works out here. First time quoting :3
Majority of opcodes function identically to their 6502 counterparts. So arithmetic and logical operations rely on the accumulator for one source operand and memory for the other, is that right? You haven't explicitly listed the register ...

Hello! I'm Ben, a 16 year old student interested in a career in computer engineering. I've recently started a project in designing and simulating a processor, and wanted to make sure I had a strong ...

6502 has been done in Minecraft, I'm sure it was talked about on this forum also. But it's been a few years. http://hackaday.com/2012/05/20/building-a-6502-in-minecraft/
But there's definetely room for one more! :)

PFFT that doesn't count! That was a software emulator of the 6502 ...

Thank you all so much for the information! The mention of having a CPC instruction is very interesting and I'm sure I could fit it in my instruction set. Very cool that you can link to individual wires on the 6502 in that diagram! That was also interesting to look at.
A little bit about what I'm ...

That's how I felt about it as well. Signed comparisons as well as other functions become more complicated in absence of it. I'm having a wonderful time trying to discover all the little quirks of the 6502 that can be improved upon in a revision of the processor. Thanks for the insight!

Was wondering if there was any particular reason why the CMP, as well as the INC, DEC etc. instructions don't affect the overflow flag on the 6502. I'm designing my own processor (a simplified, fixed-length instruction, derivative of the 6502) and wanted to make sure I'm not missing anything with ...
