FBN is pretty lenient about romsets in my time with it, it's MAME that's gay about having perfectly decrypted romsets with the precise version you're using. You also didn't mention you updated the core after "firing up retroarch".
lol, several months ago I updated all my cores and all my fucking arcade games stopped working. I got lucky and a few of them still ran but not all of them. Today I tried adding some more from multiple updated sets that match the latest FBN (1.0.0.3) and it still pulled up that message every fucking time. I deleted that fucking piece of shit and tried MAME current instead, and since it's easier to find games that are already set for the latest version, I got it working without much hassle. Except for the fact that newer games that ran fine on FBN were lagging like fuck on MAME. Unfortunately the only "solution" you will find is faggitors telling you to get FBN which I just deleted because, as I mentioned, it's a fucking piece of shit. And no, there doesn't appear to be any way to rollback core updates without already having a backup nor do they provide downloads for old versions of cores. They just fuck you in the ass with the newer updates and leave you in the dirt like every other fucking gaming anything does now. If you don't back them up and the newer core breaks something, you're fucked.
Everywhere I look online is some faggitor saying "DUHHH YOU HAVE TO DO ROCKET SCIENCE AND REBUILD THE ROM SETS WITH A TOOL YOU HAVE TO BUILD WITH VIRTUAL BASIC TRANNY PROGRAMMING SOCKS EDITION" fuck that shit, nigger. I never had to do this shit before and it's only arcade games that are like this, I never have to update console games. It's only because these faggots at MAME and FBN for some absolutely retarded reason decided updating the emulator = breaking all your roms. BULLSHIT. I will
not go through unnecessary extra bullshit because some faggot tranny developer wants me to. Fuck that. I guess I'll be enjoying 80s arcade games for a while since those are the only ones that don't lag. I update my cores every few months because sometimes some emulators
do get improved, but I suppose I'll have to completely avoid doing so now
Can someone explain the appeal of retroarch to me? I've always thought of it as a scam, a mainstreamed retro streaming service for free sounded too good to be true. I've been doing rom stuff since I was 14 and I always had different folders and emulators organized properly for roms and isos, never once have I come across something like retroarch which seems to be held together with cellotape and cardboard. The closest I did was wii u usb helper which is an application used to collate and download/update wiiu 3ds games with appropriate emulator updates. That was good though, retroarch seems to be just bad.
I use Retroarch because it consolidates many different emulators in one place for me and its available on several platforms. If I want to throw, say, Gunstar Heroes on my phone or TV then connect a shitty chink bluetooth gamepad to play it, I can do that. I am also a bit of stickler for integer scaling + proper aspect ratio, and Retroarch allows that feature even on emulators that don't support it in their standalone versions. Think of it like Steam but for emulators. It's not a streaming service, it functions totally offline if you want it to. It works fine when it works fine, and for consoles it usually does. Unfortunately it's not just arcade games are a fucking pain in the ass, many retro computers (ESPECIALLY Amiga and NEC PCs) don't even work no matter what you do. Doesn't matter if you have everything set up perfectly. They
don't work. I only ever got Commodore 64 to work reasonably well and even then it depends on the game. Even using a real keyboard doesn't work very well for games that don't support the joystick.
Also I've had this experience with mame bro. Hunting down specific sound and system drivers for mame just so one game can run is a nightmare at times.
It truly is. I'm sure you know this now, but first thing you should do when setting up a new emulator is to make sure you've got all the system/BIOS files ready. It's not too hard to find premade BIOS packs these days. Saves you lots of headaches later when you just want to fire up some games...most of the time
