i just got a mame setup for my cab but i'm having a bit of trouble making save states for cave games such as esperade and dodonpachi(the 2 i most need to practise)
its running mala and the latest build of mame..

when i got to save it keeps saying save failed due to anonymous timer errors.. is there anyway round this so i can save with these games? i know others use save states for these games with no probs

Use MAME v0.99, it is the last one which works flawleessly with Cave games regarding save states.

If you can be bothered recompiling it, make this change in mame/drivers/cave.c:

(line 126 in 128u3)

Code: Select all

static INTERRUPT_GEN( cave_interrupt )
{
        timer_set(ATTOTIME_IN_USEC(17376-time_vblank_irq), NULL, 0, cave_vblank_start);
        timer_set(ATTOTIME_IN_USEC(17376-time_vblank_irq + 2000), NULL, 0, cave_vblank_end);
}

to

Code: Select all

static INTERRUPT_GEN( cave_interrupt )
{
        timer_set(ATTOTIME_IN_USEC(0), NULL, 0, cave_vblank_start);
        timer_set(ATTOTIME_IN_USEC(2000), NULL, 0, cave_vblank_end);
}

This isn't technically correct, but it makes save states work.

Sorry to bring this topic back to life, but my cave games were saving fine for about two days and now I have the same error.

I just got mame32 plus! 0.99 (couldn't find mame32 0.99) so i can save them, but now I cannot use a game pad. When I got to click the box that says "enable joystick input", it is faded out and will not allow me to check it off. Any solutions? Sorry, I'm a little noob to mame.

Also, with the newest version, I was going to change the line of code but I couldn't find the drivers folder where I installed mame to. If someone could guide me I wouldn't mind trying it that way.

Thanks for the help.
