Ok, I've gone over the git version. I can see that a lot of work has been done to make life easier for map editors, but I feel this is at the expense of keeping the game as close as possible to the original.
First, when starting the game a search for the hideout location is performed. This makes sense (because the map may have the hideout at a custom location) but since the map is huge this takes a noticeably long time. Why does this have to be done at every game start? Do it once at initialization, store the location and be done with it. It's not like the hideout is going anywhere.
Second, the cop positions are now generated randomly at game start time, as opposed to the original where their start locations were fixed. This is perhaps required because the fixed locations may be inside a building in case of a custom map, but I don't like it. It changes the original game's feel and behavior which is a no-no in my book. Your book may differ of course, but I think the original hardcoded locations should be used, and if they end up on a non-road then search for a road nearby (I think you've already added a routine to do that). Since the hideout - and with it the initial player location - is not fixed, the cop/van positions can be hardcoded as a delta from the player's start position rather than a fixed coordinate.
About the reset steal code: your version steals reset only in some cases but not all (Altirra yes, Atari800win no).
In general it seems that the git version already contains my bug fixes, so there isn't much for me to contribute directly. I made a pull request with some minor cleanups and comments, but no functional change. If you want to fix the reset steal code please do it yourself (my solution is to also write the reset address to DOSINI and CASINI in addition to the existing DOSVEC. It works but I'm not sure it's the correct way to do it).
I don't plan to make further changes but if I do I will continue to post them here because I still like "my" version for its minimalism and closeness to the original. I will however also send update requests via git if they're relevant.
