I got the wonderful "Invalid response from PCM" on tunercat directly after the erasing flash memory message.

I've got a chip burner that supports the flash chip and the socket adapters so I've got that covered. However all I have are the .bin files I read from the PCM through tunercat. Those files are 128k. The chip is a 512k so the math doesn't pan out. Guessing, I need a 64k file in a .bin to flash onto this thing.

Can I use the stock .bin file from tunercat or is there another file I need?
