I have no flash carts either for the same reasons, they're just too expensive for me to afford currently. I do have original Sega CD hardware but it's been years since I've used any of it so I'm not sure if it's still working properly, I'm hoping it is but I'll need to test it all again. I've just not been able to have any of my video game systems hooked up for various reasons so I'm just down to my PC and some portables currently. I'm really hoping I'll be able to play my Sega CD again soon, there's a lot of good games available for that platform.
Still wish I would have bought a complete JVC X'Eye that was offered to me years ago. I was trying to limit my collection at the time due to space concerns so I didn't buy it, but it was priced very well compared to current pricing so it is a regret I have.
