yeah don't use WLA-DX for 6502, Z80 top tier, 6502 not so much.
There is no need to make another 6502 assembler, there are hundreds. Personally I recommend 64tass; it is god tier. But banking can …

The 65816 shares a similar instruction architecture to its 8-bit counterpart. Register sizes are wider, and there are more addressing modes.
It seems likely that the 65816 wider register format, co…

Is the hardware stack (page 1) underused by CC65?
If I understand well, parameters passing is done through registers + software stack.
Why is the software stack used in this case? I know the hardwar…

So I'm looking to make a Tactics game for the Commodore 64 and Commodore 128, but I want to also be able to port it to the MSX2 and possibly other architectures (68K, 65816, x86). So this seems to be …

I am really interested in this project and have just ordered a set of boards so that I can build 1 for myself. I would have preferred to order the boards populated but I can order the parts separately…

Hi!
the following lines show some examples of the usage of the EQU pseudo instruction. It happens that the implementation in naken_asm does not support the terminating colon in the label name for t…

say you do
LDA myLabel,x
you will get told that the address of myLabel doesn't fit into 8 bits and you have to do
LDA.w myLabel,x
this also happens on
STA
CMP
LDX
ADC
etc
abs can ta…

It would be nice to have forward labels for the assembler - currently only anonymous backward labels are provided (using `-->` (note that this is a reuse of the old "next-screen" FIG-FORTH block word …

A typically used indexed-indirect-* Jxx instruction will reference a table of addresses within the current PBR with an offset.
It would be really helpful to have an annotation for a pointer that al…

The [MOS Technology 6502](https://en.wikipedia.org/wiki/MOS_Technology_6502) is one of the most famous processors which was used in a lot of home computers in the 80ies.
Even today it is mostly progr…
