Sorry for infecting you with the retro-virus. My condition has stabilized into buying just one Everdrive per week. I picked up the Gameboy ED and Super Gameboy player today. I got the purple paint job so it will look good on my SNES. It's important to consider such things.
I haven't decided yet how to handle the TG-16/PC Engine. There are a lot of options for those consoles and I've seen almost all of them modded in various ways. If I get the Duo, it will be for one CD game only - Dracula X. It's been a dream of mine to play the original Dracula X. Some people dream of winning the lottery or living forever, but I dream of Dracula X on the Turbo Duo.
I've read about the Framemeister and it adds about 20 ms of lag. I was told by a retired professional gamer (who works with me) that when buying any type of HDTV/monitor for gaming, you want the lag to be 2 ms or better. CRT solves the lag problem because there is no lag. It's measured in nanoseconds, which is the same as "no lag" to a human being. He went on to tell me that there a lot of people that go online with CRTs and destroy people using LED/LCD/plasma sets. So if you're wondering why you get stomped sometimes, the other guy might be using a CRT. Myself, I won't touch anything other than a CRT for gaming. I experienced the lag problem recently with my old plasma and it wasn't fun. Plasma is noted for its exceptional picture, but the lag is atrocious. What happened is that I could barely beat the first level of Crisis Force on my plasma, yet could easily beat it on my CRT.
