My frog still won't budge

I've been working towards getting the gameplay to a point where I can control the frog. Given that it hops around in attract mode, I figured the mechanics at least were there. But it has been a bit of a slog to get to the point where it will actually move, and I'm still not there yet.

The transcode is approximately 30% complete now, and during that time I've made very little progress on the RE side of things. I've named a few timers here and there but that's about it.

I can't hold back any longer; this really is crappy code. For the amount of time I've spent on RE and transcode with this project, I can't believe I still don't have a clear picture in my head about the overall program structure. It's a tangled mess of spaghetti code with execution paths that just meander through the memory space, duplicated functionality in the code, functions that call seemingly unrelated subroutines, duplicated variables (as far as I can tell) and a plethora of flags and timers that defy a precise description of function. I can't even partition the code in my head between NMI (which is triggered by VBLANK and must run FAR longer) and main execution, they both seem to be doing a little bit of everything. This had to be written by an intern at Konami.

Anyway, the lack of structure makes it very difficult to work out which parts of the code I need to implement to get the player controlling the frog. You just need one timer to not be ticking, or one flag to not be set, and the whole execution flow breaks down. In my handful of transcodes thus far, I've never had this problem. It's going to be painful.

So the plan forward is to continue on with the transcode, and do what little RE I can in the process. I'm aiming to get the frog moving without any of the traffic or logs, turtles etc. in the picture but, given what I've seen so far, I wouldn't be surprised if the timer used (and updated in) the diving turtles routine also handles player inputs! OK, maybe not that bad, but it's a challenge.

I'll leave you with a screenshot of what I see after coining up and starting a game. Currently the code is continually incrementing and printing the number of frogs, and I'm not sure why yet. Maybe I need to look at the bonus frog logic...

It keeps incrementing the number of frogs...

UPDATE: It's actually calling decrement frogs continually...
