Can anyone tell me something about this changes?
I compare two M box files and I see load axis patch

In ori file we have
FC FE 00 C2 FD 8B F9 F2

In patched
FC 30 00 F2 FD 90 F9 F2

And #2 patch
ori
00   D2   75   F6
mod
00   42   76   F6

And know that changes

FC FE 00 -> FC 30 00 is new adress for load axis 10030 but anyone can help with rest?

I know you told me learn ASM but i know it can explain that in hex word

"Learns ASM, or Assembly Code",...

but for what assembler? It is different for each program?

Like telling one to learn a secret language, but never telling them what it's called.

From an outsider's perspective

Wikipedias :
"Each assembly language is specific to a particular computer architecture and sometimes to an operating system.[9] However, some assembly languages do not provide specific syntax for operating system calls, and most assembly languages can be used universally with any operating system, as the language provides access to all the real capabilities of the processor, upon which all system call mechanisms ultimately rest. In contrast to assembly languages, most high-level programming languages are generally portable across multiple architectures but require interpreting or compiling, a much more complicated task than assembling."

Some keyword for you checkout: c166/c167 Assembler, c166 Instruction Set Manual

Instruction set manuals are also often called "Programming Models" or something similar.
