Homebrew IPL / Bios Dissemble

[ned]

Is it possible to dissemble a IPL, I found a DOL plugin for IDA Pro 6.1

but it won't recognize an IPL because it doesn't have the DOL header

IPL is written on C. It's compiled as DOL executable, by using early version Dolphin SDK as system API.
Code entrypoint for start routine is made to 0x81300000 location (virtual address), by link script.
