Re: Why auto disassembly is tough

I will have a read about RE. For me, finding that short string with 0xD00 nails an address for working backwards to the subroutine list. When SAD misses that list, it makes for a quick find. 0xD00 seems unique, whereas 0xD000 and 0xE000 have other uses in some bins. I agree those 'set' addresses nee...

Re: weird numbers

Yes we could use any place in the rom but we have to make sure to exclude the checksum itself from the calculation. So, in calculation of a checksum adjustment, BE skips the address assigned to ChecksumStore in the definition? The EEC itself includes it for the test otherwise it would have no effec...

Re: weird numbers

Agree, the checksum is calculated by the PCM by summing all the values in an address range. The address range is defined by a start and end value that is part of the binary. BE receives an address via ChecksumStore that is ROM_TO in all the defintion files I have seen. BE then adjusts the content of...

Re: weird numbers

Yes, I hope Clint and Sailorbob chime in about the choice. My followup question is why has a word not been stuck into the logging patchcode for the purpose nulling out the change the patchcode causes to checksum? It seems unecessary to have a checksum error in place while logging when an extra word ...

Re: weird numbers

Digging up dinosaur bones here, why do the definitions change rom_to when a tune is changed?

Why is fixsum not used so that the strategy can still be recognised via the rom_to value for eec-iv?

Re: Why auto disassembly is tough

Speaking of arguments, the default output for the lookup subroutines is incorrect for URAL at least. SAD by default is taking 2 bytes as the first argument, but really needs to take 2 words for the 2 arguments. Looking at the AD_Cmd structure and associated subroutines it seems the SU naming of look...

Two different ratings in play, current carrying capacity and voltage drop. Short lengths of thin wire are ok with regard to voltage drop, BUT only if the cable can be kept cool enough so the insulation does not fail. If you use Tefzel you could run it at 150ºC, but basic PVC is good for 75ºC. Other ...

Suitability of current system seems plausible, it’s fused for 20a, and I’m sure they leave a buffer zone in the wiring that makes it capable of supporting more than its fused for.
