@rexfesto696 Ahh, I didn't think of multiplayer. That makes sense.

@Zering said in Neogeo - Problems - Hours wasted.:

Your bios is all wrong for neocd, you should have a neocd.zip and a neocdz.zip and they should not be in a separate folder. I'll have to check later but they should be in your BIOS directory.

No, as i said, you are trying to launch games for 1 system (neogeo pocket games) with an emulator for another system (lr-neocd, which emulates neogeo cd) while using the bios for a third system (neogeo mvs/aes). You need to decide on 1 system.

If it's for your father, you can never go wrong with neogeo aes/mvs, which was the dream console for anyone from my generation. Neogeo cd was the "cheap" version of that console, and while emulation cancel its main drawback (loading time), the graphics are still inferior to the mvs/aes and the games use more storage, so i don't recommend it. Neogeo pocket was a handheld, and a niche one.

Documentation about neogeo emulation is there : https://retropie.org.uk/docs/Neo-Geo/ . You'll have to read all of it and the linked documentation specific to the emulator you'll chose, otherwise i think you can give up on neogeo emulation.

@dankcushions said in GBA Not Launching (bios added):

update retropie-setup script, then install lr-gpsp from source.

Fantastic, took a while, but that's fixed it!

Apologies for not spotting the earlier post, I was scouring through the tag PI ZERO W rather than RASPBERRY PI 0W

Welcome to this forum. 👋

See https://retropie.org.uk/docs/Playstation-1/#bios

While both lr-pcsx_reamrmed and PCSX-ReARMed have an emulated BIOS to fall back on, it has limited compatibility so most games will have issues running with it (or not work at all), and all games that use memory card saves are prone to save corruption. It should be considered mandatory to manually install an official BIOS.

@mitu
tank you...
now , I can play Vigilante 8 with reicast oss.

Here it is, I hope this helps.

[edit]

Had a quick read through of the log myself after posting it. I noticed I didn't actually have a bios file to boot to. Bios file copied, problem solved.

Thanks @mitu

I found out that the problem is caused by shader I applied to all liberto emulators,
I guess Atari800 emulator doesn't like shaders.
Disabled it for this specific emu and it's working now!
Thank you mitu for answer.

Thanks for the input everyone. I've got a handful of working games and I'm happy with that for now. I have far more on my Linux tower RetroPie build that is more fit for this kind of thing.

@mitu I transplanted the configurations from a newly installed Retropie card to my existing installation, and have lr-atari800 working again.

Thanks

The BIOS started the games. Thanks @mitu!

@mitu IT WORKS! Thanks for your help it works very well!

@jbuente I got this game to run from a non-merged mame 0.78 rom pack, indytemp.zip, 352kb. I think you may be using a rom from a merged rom pack, as the errors seem to indicate mame is looking for parent/children roms. Before I eventually found it from the non-merged pack, I was using the German version. It works perfectly, other than the spelling is in German.

@mitu I have been trying to run Flink(U) and Dragon's Lair

@quicksilver thank you, I was going to try that it's nice to have a confirmation beforehand

Hmmm im getting to a point that i think Reinstalling retropie will maybe help
what do you think about reinstalling ?

@mitu Oh ok, that’s a bit of a bummer. At least I know why it doesn’t work though. No big deal, I mainly use it for MAME anyways. Thanks for all your help!

Self-Solving Problems Department: the trick is to put "cocoe" in the EMULATORS.CFG line rather than "coco"...

@dmmarti It was simpler than that - I'm a dumdum and I had so many folders with CoCo BIOS files in them from when I was trying to get it work that I'd added the Extended Basic ROMs to every folder except the right one :D

@Thorr69 Thank you so much!

Happy to help. =)

This info is covered already in the Docs - including where to copy the BIOS files, since RetroPie already configures RetroArch.
Note that some games have issues when the 'boot to BIOS' option is selected in lr-pcsx-rearmed.
