lr-fba-next and unibios

lufeig

retropie 3.7 => lr-fba-next 0.2.97.37, based on mame 0.167

retropie 3.8 => lr-fba-next 0.2.97.38, based on mame 0.173

you are using an outdated neogeo.zip bios file

get the one from mame 0.173 romset, it will work fine.

it does for me.

I can confirm this worked.

I also had wrong version ROMs, which was preventing the bios from working, so I had to go find some of the recent versions. Will report back later once I've had a chance to install.

Thanks a lot @lufeig and @gt4chuck I'll take advantage of your advices right away

Strangely even if I update the neogeo.zip file to the latest, lr-fba shows the unibios splash screen, while lr-fba-next doesn't. Are we sure that both emus read the same config file (/opt/retropie/configs/all/retroarch-core-options.cfg) and that both understand the fba-unibios = "enabled" option?

gt4chuck

Yep! I got it booted in next.

I would bet it's a romset mismatch. I should be able to verify that this afternoon later!

mauro123

unfortunately I don't think so. I have updated neogeo.zip and one rom (maglord.zip) to the latest and still lr-fba shows the unibios splash screen, while lr-fba-next doesn't :(

gt4chuck

are you using neogeo or FBA versions of the roms?

mauro123

mame ROMs. I have tried different sets, including split and merged 0.174. Always same behaviour. lr-fba works, lr-fba-next always loads the stock bios

mauro123

Just to clear up things: both lr-fba and lr-fba-next do work, but with the fba-unibios = "enabled" option, only lr-fba shows the unibios. lr-fba-next keeps on working, but with the standard bios.

If it was a ROM mismatch problem, I think lr-fba-next wouldn't load at all. It seems to me lr-fba-next doesn't recognize the fba-unibios = "enabled" option. Is that possible?

I can post the configs if needed

Thanks a lot guys

gt4chuck

Mine is working intermittently. For instance, WindJammers shows the unibios even on next.

mauro123

Tried Windjammers. No luck: lr-fba-next still loads the stock bios...

gt4chuck

Yeah it's weird.

mauro123

Could it be a bug? In that case I'd report it to the Retropie dev team. Please let me know if your tests confirm my findings, so that I can file bug report. Thank you

mauro123

Solved!

It seems that lr-fba looks for the bios under /home/pi/RetroPie/BIOS while lf-fba-next looks for it under /home/pi/RetroPie/roms/neogeo

I have updated both dirs with the latest neogeo.zip and now the unibios splash screen is showing on both emus

gt4chuck

Nice work!

gt4chuck

Ok, so I tried that and no luck for me.

My bios, when unzipped, has up to 3.1 unibios? Is that the right one?

mauro123

Have you added fba-unibios = "enabled" to /opt/retropie/configs/all/retroarch-core-options.cfg ?

gt4chuck

Oh no, I just had it enabled in the gui you can pull up during games.

I'll give that a whirl and report back.

gt4chuck

I got a chance to check on this again, and still no luck.

i've got neogeo with 3.1 unibios in there, I just did a fresh install of Retropie, i've got the line in the config file, I've got the zip in the bios folder, the neo geo folder, and the FBA folder, it works fine in lr-fba, but not lr-fba-next.

any help?

What does enabling this do? Does it just show the NeoGeo splash screen?

And your NeoGeo zip file needs to be the right version. It can be a painful exercise finding the right one. FBA and FBA Next uses different romsets, but I have no idea if there's a difference in supported NeoGeo bios.
