CSL '0401' Program Binary Disassembly Notes

[karter16]

What year did the E46 M3 GTR come out?

It was a V8. I'm not sure which ECU it used though.

Also, which DME did the E39 M5 have, probably a previous generation MSS5x ECU.

Just came across this in the GTR thread - this is from the GTR product brochure:

Here's the function that calculates the variable speed lights based on oil temp. Useful to find this as these parameters are incorrectly mapped in the XDF.

Here's an earlier version of that function in C:

I've got almost the complete source code for MSS52, that's where this came from.

Hello,
I'm trying to get Ghidra working for the CPU32 and having a few problems. Has anyone sucessfully got it running by following the instructions here?

>>> This project also relies on the following files which have been enhanced to add the appropriate CPU32 support (particularly the TBL lookup instructions).

Once Ghidra has been installed and the CPU32 support added the project files can be opened. <<<

The first problem I had was that 68000.sinc has many changes to be made and I wasn't going to do that manually - there must be some automated way to do it. Luckily I found a file called CPU32.zip in another forum which had almost all the required files. What it didn't have was CPU32.sla, so Ghidra complauned about that, does anyone know where to find it?

Finaly, when I tried to import the gar file that karter16 provided, the RESTORE is greyed out.

Here are some of the errors I get when I try to import a binary file:
