So I was going through the ROM again today trying to figure out how to disable the O2 heater check, when I came across the code where the periphery settings are written to RAM. Bez originally reported periphery values 0xFAA, 0xFBA, 0xFCA, 0xFDA, and 0xFEA. Turns out there is also another Periphery value at 0xF9A.

Since it comes before all the others, what do we call it? Periphery00? Should we rename everything so that this new one is Periphery0?

 

You know how many people would be confused if you named it 0 and re-named the others?

I vote for 00

-E

 

+1 for 00

 

The JDM to USDM vary only by one bit...0001 to 0002 (US) could that one bit the one we are looking for?

00000000-00000010 versus 00000000-00000001 so thats one off and one on for the total change?

 

Well, whats it do Mr. Fred?

 

Yes what it do

 

ok, I looked at where Periphery00 gets referenced. It doesn't control whether entire subroutine are used (like some of the bits in the other Periphery values), but instead controls specific actions within a handful of subroutines. The subroutines where it gets called are not familiar, so I can't say for sure how important it is, but my feeling is that it doesn't play a major role.

 

+2 for 00.

 

I vote to just get it up here so I can take this jerry-rigged resister out!

 

Who knows. Might turn out to be more useful if it was clear which routines it had something to do with.

Keep diggin'?
