neogeo ROMs do not load with UNIBIOS 3_3

obliv

@mitu
Thanks Mitu,
I tried what you said already earlier on. It did not work. I have downloaded different versions of the neogeo.zip file, checking the content and also trying to use the latest updates. Nothing worked.
However, one thing I did not check: how can I make sure the ROMs I have are fitting my emulators/BIOS ?

I have to say that the ROMs are working on NEorage-x , the emulator I have on PC. In this case the BIOS is old . I am now trying to use that old BIOS and see what happens. I will update this post once done. UPDATE: it does not work. I actually tried to use the newest neogeo.zip with my PC emulator (neorage-x) and it works, so it is not a problem of the BIOS file I have, neither of the ROMs: they are usable with both BIOS I have.

Pi Model or other hardware: (3B+)
Power Supply used: (5v, 2A)
RetroPie Version Used (4.4):
Built From: (Pre made SD Image on RetroPie website)
USB Devices connected: Joypad Logitech wireless. Keyboard
Controller used:
Error messages received: ROMs do not load
Log found in /dev/shm/runcommand.log (if relevant):
Guide used: (ETAPRIME youtube channel, RetroPie official Wiki)
File: (I guess the BIOS files ?)
Emulator: (lr-fbalpha)

@obliv Start the game with verbose logging enabled - through the Runcommand launch menu -, then get the contents of /dev/shm/runcommand.log and then paste it to pastebin.com so we can have a look.

Doesn’t matter if a rom works on a different emulator on pc. Sometimes Mame/fba Roms get updated with a better dump of the roms themselves. If they have been, FBA is looking for the newer dumps and couldn’t care less if and older dump is close enough. It just won’t run. So you need to find a newer rom set to work on the current FBA

@mitu
stupid question: how do I paste it from the Pi to the website ?

lostless

@obliv you can ssh into it and copy and paste from your computer.

obliv

@lostless I can't manage now to connect with SSH for some unknown reason (neither putty or juiceSSH seem to work in this moment...).
I could put here the screenshots... can I ?
see if you can get them from here

Configure SSH and use WinSCP to transfer the file. From the looks of it, your ROM is not correct and lr-fbalpha doesn't load it. Get another version of the ROM and re-try, your problem doesn't seem to be related to the BIOS.

obliv

@mitu is there a way I could make sure before downloading if the ROM would work or not ? or is just random trial and error ?

mitu

@obliv You can use something like ClrMamePro or RomCenter to validate your ROMs or get a correct ROM set for your emulator.

ClrMamePro

thanks, I will try. however.... I have downloaded previously a full ROM pack (almost 1 Gb). Is it likely they are all wrong ?
Are you sure that the problem is in the ROMs ?
I can try those softwares and validate anyway...

obliv

@obliv I tried with Rom Center
I was able to open a folder with the roms (182)
they are "unknown" to the software...
they do not seem to be corrupted (I tested them) and indeed they are working on my emulator on PC (neoragex).

I also downloaded another rom pack
same as above.

I haven't tried to use them on RetroPie
but I am suspecting.... the problem might be not in the ROMs... or what do you suggest ? :)

mitu

I still suspect the ROM is at fault. Here's a log excerpt from launching Metal Slug 4 on my system - both ROM and BIOS files are in the same folder

@mitu mh... well how can I argue against this ? :) thanks for your help. I would then try to use the other ROM pack and see what happens. At this point is maybe better to test ROM by ROM...
Is there any way to save the ROMs I have ?
I do not know how strict this forum is but it would be helpful to use your ROM so that we can understand what is the problem...but of course I do not know if files can be shared here

mitu

@obliv As I said in the other thread, there's no ROM sharing here. Please stop asking and re-read the Forum rules. You can verify your ROMs using RomCenter/ClrMamePro - I guess you didn't go through with that - , there's no need to compare ROMs.

One idea - did you keep the names of the .zip files from the ROM set you downloaded or you renamed them ? My ROM zip is called mslug4.zip, yours appears to be named metalslug4.zip.

obliv

@mitu sorry. Thanks the new rom works and is called like yours. Thanks again ! :)
I did check with Rom Center yesterday though. It did not prompt me any error about those ROMs. That is why I still had the doubt. I will simply replace the ROMs. Thanks again !! :)

lostless

@obliv never rename arcade / Neo Geo roms. They won’t work if you do
