Samurai Shodown unplayble demo on MSX+V9990

New version (0.15.2): now I'm enabling both layers, instead of just B layer.
Layer A is full of clear patterns, so it won't be shown anyway.

When you or someone else could try, here is the ROM:

Thanks

Great!
Thanks for all help.
I already submitted issues to both openMSX and WebMSX.

For me, the current version (0.15.2) works on both emulators:

You should enable v9990 and set output to it (or dual video, as I did)

I recommend you replace gfx9000 by video9000 instead and use Video9000's exclusive superimpose register at 0x6f to make the emulator seamlessly display the screen as if it were a single input.

In my TCL initialization script I write:

ext video9000
set videosource video9000

And I do this to turn V9990 output off:

        ld a, #0x10
        out (#0x6f), a

And this to activate V9990 output when I am ready to display to the screen:

        ld a, #0x18
        out (#0x6f), a

You can put it in a function like I did:

// use Video9000's superimpose control support
void set_ctrl_port(uint8_t byte) __z88dk_fastcall
{
    byte;
    __asm
        ld a, l
        out (#0x6f), a
    __endasm;
}

If you don't want to add support for Video9000 in the final release, you could even use this as a debug mode to ease up development.
