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
