Mortal Kombat Plus+ Compatibility

@greenhawk84 Sadly, the sound buzzer glitch already revealed some bad hacking issues with this romset (might be why it's tagged "beta"), so i believe this hack was never meant to run on anything that is not MAME (meaning it might not even run on an original midway Wunit cabinet either). It turns out the tms34010 cpu interpreter FBNeo is using for Wunit is totally different from MAME's, and replacing this cpu interpreter one of our contributors wrote from scratch by a backport of MAME's, just because of some bad hacking, doesn't sound right. So i don't think this black screen freeze in attract will be fixed anytime soon.

@barbudreadmon man, all that effort to come to this point. Well perhaps my initial thought that Mame2016 would be perfect for the MK+ games is still valid.

The Plus games are designed to be original hardware only. Anything else compatibility wise is up to the person/persons who wish to use it in emulation. Emulation only bugs are not addressed since there are so many variables to an emulation setup. FWIW I have no idea if the problems you speak of are present on hardware. It is and will be a beta for the foreseeable future and is likely years from a satisfactory conclusion.

@zoltan45 Thanks for the heads-up, we won't do more investigations in this matter though, the umk3 official romsets now work properly and that was our original goal. We already spent so much time debugging those games while we aren't fond of them in the first place, so tbh we couldn't care less about that remaining issue since it's not even game-breaking.

@zoltan45, it seems like Mame2003-plus is working 100%, hopefully this is all I really need to enjoy the games until a possible later Mame revision if someone chooses to work on it. Thanks for the information.

Hello, just wanted to update on this, I tried Ultimate Mortal Kombat 3 Plus Beta 2, released this year, and performance seems good on FBNeo.

The bug where the game is left to run in attract mode and the screen goes black is still present. Also, if I set the volume higher in the dipswitches, I get some blown out sounds during gameplay, so I just leave that default.

I have not tried other cores yet but I will see if others have different performance/bugs.

As already mentioned, we don't plan on fixing this, iirc you can get around this bug by disabling the "improved" attract mode in service menu if it's bothering you.

@barbudreadmon I was messing around with MK2P and UMK3P last night and they were running nicely in FBNeo. I switched the UMK3P attract mode back to normal and it was working, so thanks for that tip.

I anticipate them to keep updating these games and eventually release Mortal Kombat (1) Plus. Pretty cool romhacks !

Not sure if anyone plays this to notice, but MK2 Plus player shadows are missing on Mame2003-plus and FBNeo.

I tried regular MK2 on Mame2003-plus and they are also missing there, but FBNeo does have player shadows in regular MK2, as well as Mame2016.

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..
