Is Sega Genesis Classics on modern consoles faithful to original hardware?

[SavannahM]

I recently picked up the Sega Genesis Classics collection on my modern console to relive some childhood memories, but I'm finding the input lag and slightly off audio emulation a bit jarring compared to my original hardware. I'm debating whether to invest in an original Genesis and a CRT again or if there are better modern solutions like the Analogue Mega Sg or specific emulator settings that can perfectly replicate the feel. For retro gaming enthusiasts, what's your preferred method for playing Sega Genesis classics today? Have you found any of the modern plug-and-play collections or FPGA consoles to be truly faithful, or is hunting down original cartridges and dealing with aging hardware still the only way to get an authentic experience?

Original hardware with a CRT is still the gold standard for me. The way a 240p image from a Genesis looks on a CRT, plus authentic cartridge audio and near-zero input lag, is notably different from HDMI upscaled emulation. If you have access to a decent CRT, pairing it with a clean cartridge and a solid power supply (and maybe a test with a small CRT for space) is hard to beat. If a CRT isn’t practical, the Analogue Mega Sg is the closest modern option—it's FPGA-based, plugs in via HDMI, and the Genesis core is genuinely faithful to the feel. A couple caveats: it doesn’t support 32X or Sega CD, so you’ll need the original hardware or a separate adapter for those expansions.
