@danyo Got it running. Thanks!

Just for another subjective opinion, I'm content with MAME 2003-Plus (in arcade) and FB Neo (in fba) next to each other and see no need to change that after moving to a Pi 4. For more recent MAME versions, I have my bigger computers. But I didn't feel the need for that for over two years now.

In RetroPie, the NeoGeo system is separate, so you can copy the NeoGeo romset collection to the neogeo folder and the arcade only romset to arcade. You can combine them if you want, but you might want to keep neogeo separate just in case you'd want a different configuration applied to it (see this post for an example of why you'd want that).

@Neo-Rio why not just install and use lr-bluemsx?

thank you @barbudreadmon , i had made the leap of faith that since, for example, Xain'd Sleena had an entry in the file it was supported. I'll retry 1942... Appreciate the confirmation.I'll just have to keep grabbing a save state until some support hopefully comes! If i had the ability I'd look into how to do it myself...

@langest Thanks for reply, mine were working very strange I'll try another bios then. Thanks Sim Edit Yes bios was the problem sorry for wasting your time. Thanks Sim

@TheBlueBanner could you try again when running in verbose mode? it's an option in the runcommand when launching

@barbudreadmon More weirdness: I normally only use the arcade folder, so as a test I copied the rom from there to my fba folder and it worked as intended. I then moved it back to the arcade folder and it now works as it should... So problem solved, I guess.

@barbudreadmon Cool, I'll check it out soon.

@WeirdH said in FBNeo glitching roms after update: This did the trick, awesome! A thousand thanks to you for helping me. Your very welcome my good man glad it s working for you :)

@barbudreadmon nice, thank you, I will donate to the cause.

@BuZz ok thanks. I was actually able to get it by updating from binary. It showed I had it and that it was installed, but I had to reinstall/update and it’s now working. Thanks

@Clyde Done and pushed, thank you Now I've got a first user on Mac and a tricky issue with Tkinter not scaling correctly on that !

@giangio cchip_b22-15.53 is in the rbisland romset while cchip_upd78c11.bin is in the cchip romset, both files are required and part of recent MAME romsets (if you are using FBNeo)

OK, may have solved this, Button B is now working and have swapped over A and B so A is fire, B is bomb for instance by going into the Core remap options. If this is indeed now working, can someone just point me in the right direction for which options to change in the core remap so that my C and D are the same as C and D on a neogeo control panel?

@barbudreadmon Initially I did not have any intention, but after I read this on "validating, rebuilding and filtering": "Sample: Some games require an additional zip file with recorded sounds or music in order for audio to work correctly" Then the doubt came up I will read your link and will come back later. Thanks
