@sirhenrythe5th Any progress with this (HEX editor)?
I am facing the same exact issue with these two roms and I tried with the files generated with flycast on a PC and the result is the same (i.e. still freezing at start)...

@sepsism wow it looks great!! Which cabinet plans did you use? Do you have any more information how you did this?

Thanks!!!

@Sepsism maybe KOF 94 or 2003, I love the falling letter

Ok the correct way is:

Turn on setting mode
Do a reset
Go to Setting up the soft dip > Slot 1 Metal Slug> Turn on blood
Navigate back and select exit
It should display DIP SW 1 OFF!!! or so
Then turn off setting mode in rgui

Edit: It should create a .fs file in the romdir.

Just in case someone stumbles upon this thread while searching, I was able to fix the issue by clearing out my "Nvram" folder. Apparently it had some corrupt data in it.

A Pi3 with lr-fba does not need overclocking. The slowdowns you see are either:

something that also happens on real hardware when there's too much action going on - part of the charm!

CPU throttling (check the temperature) or undervoltage

some games are programmed to look like they're slowing down (drama effect), it's something bizarrely intentional

@AlexMurphy

Terrible stuff. I actually have a copy of the shooting script that has the Wookie parts translated on the page. It doesn't improve things. Although 'The Star Wars Holiday Special' certainly holds the crown as the absolute worst, retro-gamers can seek out their own personal nightmare before Christmas with the ill-conceived 'Christmas in Pac-Land'. Theses shows are not without merit however. They're a great stand-in for ipecac if you can't make it out to your local pharmacy and you've run out of eggnog.

@rbaker fixed it, I just updated all my stuff through the source and they work now!

@mike8906 said in Unable to start metal slug 3, 4, 5 rom - Raspberry PI 3, Retropie 4.0.2:

Is it realted to the limitation of the Raspberry Pi3? Or can it be fixed?
I use a memory split of 320 as advised in one of the retropie setup tutorial.
Does the game really requires so much power that it slows down while lots of explosions/enemies appear on the screen?

From the RGUI menu you can "overclock" the NeoGeo. I did that and it works perfectly. I heard that on the original console it lagged too, it's not really the RPi's fault. Still that game is freaking addictive and one of my favorite arcade games.

@purehippo said in Neo Geo Setup:

@rbaker How can i tell if i have the correct neogeo.zip? Also how do i tell if the roms are correct? Do i need the UNIBIOS for lr-fba-next to work right? I dont believe i have gotten this file.

There is no way to tell from a single file in my experience, you are in trial and error mode. It's best to locate and download a full set from one of the many sources out there on the web and start from there. A full set could be anywhere from 2GB to 50GB depending on the version. Best get a 0.78 set to begin with as that will work with lr-mame-2003
