$42 hack and hiway lean cruise patch

[jim_in_dorris]

I haven't spent a lot of time looking at the $42 hack, but reading the hiway lean cruise thread got me thinking about $0d and lean cruise. I know there isn't a patch for $0d, but I thought if I understood the $42 patch, maybe I could come up with something like it. That's where I ran into my first problem. The $42 hacks I have and the Hiway Lean cruise hack don't match. That is to say, that the address in the HLC hac is in the middle of a section of code for some of my $42 hacks. The HLC asm file has an org at $DB04 for a starting address, and my $42 asm files have either code there (ARJU is one) or the hack is way past the end of the source code addressing. I am not sure where to apply the patch. I hope to come to a better understanding of the $42 code from this exercise as well as how the HLC code works. Thanks

Lean Cruise was in $42 from factory and turned off. I'll attach a bin stock and one with the patch so you can see what is happening and maybe figure out why locations are off? I used ASDX as it's in the hacs.

There's only 48 byte changed with the patch so it's easy to find with difference tool in TunerPro. The XDF has the HiWya Lean Cruise paremeters so you'll know exactly where they are.

But since $0D didn't have it... that I know of it would have to be built. There is a Paremeter in $0D I read that says it could be used for LC, but never got into it. Was just a trick and not actual LC.

Thanks Mark. I usually look at the assembly code directly instead of the bin files, but I may be able to figure it out with the difference tool. I unzipped my $42 folder and it contains an ASDX hack with the source code, so that should help a lot.

Edit: A light just came on.... I think it was the train... The ASDX_HAC source I have is only the parameter tables, not code. back to the drawing board

Edit #2: I have an ASDZ_HAC that has the code in it. It matches the ASDX.BIN at the point of the HLC patch. I now will build a source code file with the HLC patch and then I can start to dig into it. Hooorah!!!!!

I figured with the Hiway ASM, stock bin and patched bin you could figure out what was happeneing.

Look through all those files in the zip, some are differant as to what they contain. I know one has the code after paremeters. HTH! I sure can't...

I now have a ASDX_HAC.src that I will assemble and compare to the bin file to verify the code section. When they match, I will add in the hiway patch, and you can add the files to the $42 list. I might as well do the esc_done patch as well. It might take a while though, I have to edit about 9,000 lines for it to assemble.

That bin I gave you has the Lean Cruise only patch on it. Not the ESC Done patch. FYI...
