Title: KFZW 16 bit load axis Post by: Dejw0089 on April 13, 2020, 11:38:32 AM 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 Title: Re: KFZW 16 bit load axis Post by: mophk on July 01, 2021, 08:33:19 AM bumping this as I have not found anything about this and would like to know more.

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."

Anyone with a CS degree knows what ASM is, it isn't a secret.

Title: Re: KFZW 16 bit load axis Post by: RBPE on July 02, 2021, 07:19:32 AM If you're asking why loads are increased rather than how to do it learning asm etc, then the FR will tell you.
Alternatively, theres some info on here regarding iop/irl inverses, extending past ambient for boost loads etc which should give you an idea. Prj's post here for example. http://nefariousmotorsports.com/forum/index.php?action=printpage;topic%3D3765.0 And the ST/Keil datasheets should help you with regards to reverse engineering c166/c167.
