SH-4 Emulator

So is there nobody out there that has an answer for me?

There is no true HARP SH7750 emulator for an x86 based system available
Was there a specific device on this platform you wanted to emulate?

For Windows CE for example try:

I wanted to run linux off of it and be able to load or unload disk images. Create programs specifically off that CPU so that porting to the Sega Dreamcast would be somewhat easier.

Well there are a few good Dreamcast emu's but none that I know of with a programming interface.  Would they be any help?

See, I know that there are Dreamcast emulators, but the problem is that I want a straight SH4 emulator or hardware card with a hardware SH4 on it. So that I can compile versions of Linux and other programs based on the SH4 processor.

I know there are already versions of Linux for the SH4 but I truely want to understand Linux and cross compilation. The project I'm working on requires me to customize a version of Linux (very light on memory, but still utilize X windows for Display).

I know that with GCC I can compile programs into SH4 binaries, but I want to be able to TEST them too with a decent degree of accuracy.
