The thing is that ROMs and emulators on PC offer some big incentives - stuff like Launch Box, settings and shaders, raw power of the device, controller support, etc. The emulator used/bundled here is apparently inferior to even one SEGA themselves used before on older devices. In theory the ROM sites have a disclaimer that this is archival purposes, to be downloaded by legal owners, etc. - in practice anyone can download them. But if it wasn't for these borderline illegal sites the games would D I E. Nintendo famously used an 'illegal' ROM of Mario and sold copies of it, some people speculated that they lost the original material. Yes, I guess piracy sucks and is technically illegal but even I (and I don't play many games at all) had to download cracks for physical legal copies I owned (including once for a game published by SEGA, funnily enough).
