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
