Tre-cool has set up a Ghirda project server if anyone wants to contribute.

I'm re-attaching here files from the other thread if you want to download and play along.
A couple of notes on the address workbook
- It's about 2/3 of the HP definition.
- I'm currently labelling the tables in Ghidra and am noticing a bit of inconsistency with how tables are accessed which is causing some of my addresses to be off by a couple of bytes here or there. E.g. some tables have the axis size referenced whilst others which also might have axis info are not being referenced. Stupid GM. I'm fixing that up now as I go through labelling the tables.
- The address workbook is for Ghirda, it is not suitable for a straight xdf conversion (but it is an excellent starting point).
- I'll periodically update the workbook here.
PowerPC:BE:32:MPC8270
A couple of registers need to be set. Be sure to re-analyse the file after changing these addresses. The following values are used for the OS's that have been peeked at so far:
r13 = 0x400000
r2 = 0x8000
My end goals are:
- Locate extra tables / flags that might assist with torque converter tuning.
- Find PCS1 (line pressure solenoid) and see if there is a way to modify it's pressure response without having to edit the torque tables in the ECM. Even better would being able to scale the incoming torque value.
Side note, for comparing bins have a try of WinMerge if you're currently using HxD. I found it easier on my eyes and quicker to navigate differences.
