MAMEWorld Forums - Emu Loader - New feature: MAME Custom Parameters

What ? So you can attach devices and modules to MAME machines (mostly for computer machines and software lists)... stuff like that. Emu Loader doesn't have this feature and this is easiest way.
No more .bat files sorcery!

... update August 12, 2021...

As it turns out, there's no need for a "game" tag. It's still supported for extremely rare cases, but it should not be used.

For MAME machines with no softlists, the game name is always added after mame.exe, and then the custom parameter is added after it (this order is hard-coded into the frontend).

For software list games, it does not matter where the "-cart gamename" (media + game name) is located.

For software list games you will be able to enter the MAME machine before the parameters. This way, it will overwrite ide the selected machine for that softlist game...

The machine name must be the first argument (software lists only), then "required device parameter" next (a cassette player device, a floppy drive, etc... depending on the machine you're using). Then you can have a plethora of parameters. And at the very end, the media+gamename parameter.
I will add a reminder/info text in there, to avoid mistakes.

I did a bunch of tests with different games of different software lists, and they all worked, even with tons of other parameters before -media+gamename parameter.

The media param is not required. If omitted, it will will be added at the end by the frontend of the string along with the game name.

Here are some examples:

Code:

    TI-99/4A cartridge game (ti99_cart.xml software list) with the arguments
    to "attach" the speech synthesizer'
-ioport peb -ioport:peb:slot3 speech -cart1

    Same as above, but without the -cart1 media parameter
-ioport peb -ioport:peb:slot3 speech

    Intellivision cartridge game (intv.xml software list) with the arguments to
    "attach" the Intellivoice Voice Synthesis Module
-cart1 voice -cart2

    Any MSX 1 cart game (msx1_cart.xml software list) with a specific MSX machine,
    overriding the selected MAME machine for this soflist game.
fxaiwx 

    Same as above, but loading the cartridge in "slot2"
fxaiwx -cart2

Note the last example, only a custom MAME machine was entered. The media parameter -cart1 was omitted, only a custom machine name is set. Emu Loader will add the media param and the game name automatically when running the game.
