Saturn BIOS Dump

[slinga]

Hey all,

Long time no post. Anybody interested in posting the Hex Rays (IDA Pro's decompiler) output of a US\EUR BIOS? I'm just curious to see what it would look like.

I know IDA Pro Advanced supports SH2, not sure about Hex Rays though. If anybody could help me out, I would appreciate it.

I decided to take a different approach to try and understand the saturn BIOS. Using yabause I can see that a BIOS I supply is loaded to 0x80000-0x100000. I'm outputting all of the addresses (PC register) executed by the SH2 and I'm never seeing it execute anything in that range. Thanks in advance.

The BIOS is loaded to 0x0 thru 0x7FFFF and is mirrored at 0x80000 thru 0xFFFFF. All normal BIOS access occurs at 0x0 thru 0x7FFFF.
