Good question - the only games that need it at the moment are -
1 - Romancing Saga 3 - hires equip screen drops to 42/43fps.
2 - Vortex - not 60fps constant
3 - Star Fox 2 - same here - hovers between 55/53fps and 60fps when it's not having a bad day.
the main problem is that the development environment (retail PS3 with no debug FW) sucks - I'm hoping OtherOS++ gets released soon that we can run jailbroken / with a CFW on a firmware above 3.15 - we don't want to have to go through this ordeal of the app hanging everytime we try some stuff out with the SPUs - that would be absolute hell.
Another obstacle -
1 - This emulator (or parts of it) might not be parallelizable - in the sense that we can't just offload certain parts to a different CPU and have the main CPU (the PPU) get on with its job. A lot of emulators like MAME can't really make effective use of multi core CPUs beyond a dual-core for this very same reason.

wouldn't really need a debug though to try, just code in some hefty error detection into a dev build. Pain in the ass signing and packing though I guess every time you make a small tweak. I'm pretty sure you can make a mfw for 3.15 with the mfw program though and asbestos 1.5 does an ok job of booting linux only the bootloader is very restricting but the same sort of hardware access grafs method will bring (except rw access to ram but thats not really needed for this)
It'd help with the input lag too, and it'd make a decent gui feasible.
