just made a shooter for the C64

Great did you write this in 6502 Machine code?

Kind Regards Baggey

I did it all in Machine code, just started with assembler and boy oh boy its a hard nut to crack, but its fun.

Ive nearly completed a ZX Spectrum Emulator and would next like todo an Oric Atmos emulator.

However i know nothing about 6502. The C64 is Definatly more Popular But information on each code and it's number are a Mine Field.

If you look at Z80 code it's very easy to get an instruction and find it's Codes to use it.

However 6502 is a complete mess! Do you have a good reference to all Op-codes and there code numbers in the form of a Z80 Layout.
Going into index, Absolute etc is not needed really. 

As a c64'er What feature's would you like from an Emulator to help you CODE?

Kind Regards Baggey

sounds like your doing something cool  Baggey, I would like  a Z80 machine like the Next, but I dont have cash r oppertunity at the moment, I think I seen you have two nexts

you can get the opcodes refs online, I have a text file i found, but your right it is messy, .

I would wat from an emulator a way to make disk images like you get on a real machine, 

either way - what you are doing with machine code is very good work 

Thanks Adam, it does feel like the 80s again

Baggey, this link should give you exactly what you need.

I believe there are undocumented op-codes but probably just demo-coders and people really hacking at the hardware resort to using those.

Totally agree, kudos for the low level work.

thanks, its praise indeed from coders
