Here are some SPC loader tests I just finished: spc_loader_tests.zip

They test that RAM is loaded properly, CPU registers, DSP registers, $F0-$FF, and that $F4-$F7 are restored before the first instruction can access them. The RAM tests do several regions separately, in case your loader patches it:

$00-$EF
$100-$1FF (ignores three bytes just under sp)
$200-$FFFF (excluding echo buffer)
Echo buffer
Three bytes just under sp

I could host/mirror the files at jiggawatt.org if you send them to my gmail account (micol972).

Thanks for the offer. Koitsu has generously given me some space, and I've fixed the link above.
