I've noticed that the address locations for the 1D maps are also in the ROM in 4-byte chunks like the 3d/2d references (for example, "0x000C0440". I've seen them in the 0x14xxx range, and every 1D map location I've tried is found in the ROM. I can't make out any pattern to the data in-between, so I'm assuming that this area is all "programming logic". Don't know if this useful or not for finding tables, but I was able to find a few 1D tables I needed in an unknown revision by finding similar "in-between" data from a known ROM and then tracking down the address on the unknown ROM.

Thanks for the info. I'm planning on attacking the Subaru ROMs soon to try and get most of the map addresses for all of the ROMs I have and put them into the next release.

Colby, I haven't checked yet, but does IDA Pro have a built in module for the DBW ecu's or are you using something else?

I am using IDA Pro Advanced 5.0 - It supports the SH processors.

I have the SH4B on my IDA Pro 4.9, have you found a good entry point for the 512k/1mb files?
