@windg Interestingly, only partially. There is no crash, video with character spinning around is playing, but bio text is missing, its just empty background.

EDIT: They have fully fixed this.

So hate to resurrect a two year old thread.. but my original lr-mame mod for mortal kombat plus seem too old now (5 years now) giving segmentation faults.

So I built new ones based on the newest build lr_mame 0.237. These were built on Ubuntu 22.04
but might work on pie's if anyone wants to try them..

mkp_mamearcade_libretro.so is for Mortal Kombat Plus
umk3p_mamearcade_libretro.so is for Ultimate Mortal Kombat 3 Plus

Just copy them both into /opt/retropie/libretrocores/lr-mame

Be sure to adjust your configs/mame-libretro/ emulators.cfg like so:

mkplus-mame = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame/mkp_mamearcade_libretro.so --config /opt/retropie/configs/mame-libretro/retroarch.cfg %ROM%" umk3plus-mame = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mame/umk3p_mamearcade_libretro.so --config /opt/retropie/configs/mame-libretro/retroarch.cfg %ROM%"

Then set the emulators in run command.

They use the original rom zip names so change your plus roms to:

mk.zip and umk3.zip

You'll be overwriting the original roms if you care..

@mahoneyt944 said in Has anyone tried to get MKII PLUS+/UMK3 PLUS+ working?:

Mortal Kombat 2 Plus Beta 2 and Ultimate Mortal Kombat 3 Plus Beta 1 have been officially added to mame2003 and mame2003-plus. Update these emulators from source to play these along with many other enhancements made daily. Now bootstrapped to fix low volume and CMOS errors at boot.

ROM Names

mk2p umk3p

Pretty cool. I just set these up with both MAME 2003 (as .7z) and FB-Neo (as .7z). Best of both worlds.

@f4cepa1m Worked well, thanks for sharing!

Does anyone have any idea why the mapping for the up motion on joystick would be different for player 1 than player 2? This problem only occurs on ultimate mortal kombat. I'm sure the joysticks are wired properly.

@Amplifuzz

You don't really need a ton of custom video modes, since the resolution stays the same, and you only have seven or so different refresh rates at maximum to deal with. Two config lines like "lcd_native_res=1920x1080" and "lcd_range=50-60" or whatever the monitor supports would cover it.

on groovymame, sure, but raspberry pi only understands discreet videomodes. you have to tell it when you want to use a new videomode. in retropie, using the runcommand, you would have to add each videomode to the list, and when selected they would have to call the api command i linked above (since these aren't videomodes in the raspberry pi's limited list of videomodes)

I'm afraid that the whole 'snap to the closest available refresh rate once the native ROM refresh is detected' part is best handled by the emulator itself, as well.

agreed, but for that to happen someone woudl have to update CRT switchres (or something similar) in retroarch such that it can communicate with the pi's custom videocore API calls (see the link above).

i'm told that you can get crt switch res to work with pi, but only under X. we don't use X in retropie. there's some info on this on the (huge) crt switch res thread over at libretro: https://forums.libretro.com/t/retroarch-native-crt-support

@eldrethor yes i didnt think of it... 2003 mame are ok yes.

Thanks for the updates. I am glad it is recognized as an issue. Maybe the speedhacks will help the gameplay once all of this is resolved. I am always up for some improvement!

@mitu Thanks for the help. Sorry for the bad move of asking for support on another image. Take care.

I believe all the mame emulators will play these 2, so the answer above applies

I play almost everything on FBAlpha with only a couple games on Mame2003. I am using a standard RPi3.

@caver01 , thanks heaps mate, that did the trick and now it's all good!
