    Definitely! VBT has been trying to port a NES emu to Saturn, he tried two different ones. He even had games running, but then concentrated on SMS Plus. There should be even an SH assembler CPU core available, like the one from gleam for Dreamcast.


    @fox68k: hopefully FAZE will have it's source code available, so that it can be made working on a SH2, too.

    Yes, the source code will be available to the public.

    I was wondering what changes have to be done to the sources to be SH2 compliant. I guess it will be big endian assembling among them but i cannot figure out anymore at a glance. I am interested in this issue, so please let me know about.

    By the way, FAZE is starting to run many ZX spectrum games nicely so keep tunned.

    Cheers.

    Differences between Saturn SH2 and Dreamcast SH4:
    - no unaligned accesses (word, double word) allowed
    - big endian
    - subset of instruction set (examples I remember):
    -- no floating point instructions
    -- misses the easy shift instructions, to shift any number of bits with a single instruction, instead may need to compose it with multiple shift instructions

    about 9 years ago you could buy softmods on streetmarkets in South America when the pirates started flooding Saturn games. They were cart based with a switch to choose US/EUR/JAP country and in one variation even had the additional 4mb ram built in

    I wonder where these have gone.....
