lr-mame2000 save state?

[Dekard]

I am using a Raspberry Pi 3 with RetroPie and have most of the common emulators and cores. Its been an interesting ride learning how to manage retropie from the command line and up until now I have solved all my problems from retropie.org.uk, but lr-mame2000 save state seems to be a dead end every where I look on the internet. Mots of the posts are up to 5 years old so it seemed wise to ask if I am missing something or has the situation changed. I am using Mr. Do! as my example arcade game that will not save state in lr-mame2000. I have changed the default emulator for this rom in the set up screen after launching the rom. The other emulators i have tried are
advmame-0.94
advmame-1.4
advmame
lr-fbalpha2012
lr-fbalpha
lr-mame2003
lr-mame2010
mame4all
pifba

Only the mame4all will launch the rom but then none of the buttons work even though the .cfg files have the same button assignment so i think thats a red herring.

With all the brain power out there, has this lr-mame2000 save state issues been resolved yet?

or

is it possible to find another emulator that will run games for lr-mame2000 but with save state enabled?

There are so many games that fall into this category its quite frustrating :-)

The recommended emulator for Arcade games are lr-mame2003 (or lr-mame2003-plus) or lr-fbneo`. They should work fine on a PI3 and they support save states. See the Arcade Quick Start for details on what ROM sets are supported by each emulator.

As the name implies lr-mame2000 is the 2000 version of Mame and it will not receive any updates anymore - it's frozen in time.

@mitu no chance of seeing newer mame versions be backwards compatible with roms for mame-2000?

[dankcushions]

@Dekard just use the right roms for the version of MAME you want to use, not the other way around. anything supported by mame2000 will be supported by all the later ones, but you'll likely have to download the correct romset for the version in question.

[Dekard]

To clarify if a particular rom exists for mame2000 i should be able to obtain a version of that rom for mame2003 and so on? I am feeling i do not understand because I am not finding that to be the case

@mitu @dankcushions Fwiw, and I would have to double check to confirm this, but I think that save states in lr-mame2003 and lr-mame2003-plus aren't working currently(?). I was playing last night with my cousin and had a similar issue. Save states are not supported by this emulator. Or something to that effect. Worked fine when we switched over to lr-snes9x.

(Note: this is with my fkms build. Very well could just be me.)

@hooperre save-states capability is on a per-game basis: https://github.com/RetroPie/RetroPie-Setup/wiki/lr-mame2003#save-states

[mitu]

@hooperre I think not all drivers (i.e. games) support save states in lr-mame2003, hence the message.
If you look at https://docs.libretro.com/library/mame_2003/#features, you'll see that save states are game dependent - so it's not all or nothing.

yes, i do not know of any games that were supported on one version of MAME but not a later one (although there's probably a few rare and brief examples). the file name (and contents) may be different, but the game itself should be supported. do you have an example.

@dankcushions Mr. Do!

@dankcushions Mr. Do!
