I only said that because of the size of the 7z. He is correct. Some of the Sega Genesis games had a problem loading. I think it was Sonic had that issue. I remember it used to pop and sounds lag. That when I was using a shitty computer back then. I don't notice it now because I'm using a better computer. Better computer is the faster it will load. Shitty computer is the slower it will load. Have something to do with pressing the size down.
If the ROM's loading fine then there nothing to worry about. That mean your computer can handle it.
