A lot of emulators are great which is why I never bothered buying certain systems such as neogeo, turbo grafix 16, and even the NES. the emulators just played the games fine and I played the crap out of em. You can't really compare a jag emulator to a system that has been worked on and perfected in emulation over and over such as nes, tg16, any sega cart based console, coleco, 2600 and on from there. The Jaguar stuff took longer to come out and I imagine it still needs some work. It would be cool to be able to fully emulate it on a PC because then everyone who ever wanted to check out the games could and you wouldn't need to wait for a flash cart to get released again (or hope that someone doesn't think the system is an entire waste of time and effort, which I am uncertain is the case with KRIKzz so I'm not implying that but it could be

).
There are certain systems I prefer to use the original console and some consoles I actually own I would rather play on emulator, or at least some of the time. Sega genesis is one I would prefer on emulator as the actual hardware is clunky and junky. But the caveat with playing genesis on an emulator is 32x is only emulated on x86. But I wouldn't spend over $100 on a 32x add on anyway. I do own a flash cart for the genesis but I prefer not to use it when I have a Wii plugged into the same TV set.
Hm well KRIKzz NES flash cart is beyond awesome but I played so much nesticle back in the day and the emulators on dreamcast and such that I'm uncertain if I'm ever going to get an actual NES again.
NGPC games, last I checked, most of them were pretty cheap unless you are looking for some of the more rare imports (which probably aren't even rare at all..) I just bought gal's fighters and it was cheap and pretty fun, nice graphics and smooth gameplay.
Anyway hopefully the next system KRIKzz does, if he does more, is something cool. There's Flavor working on wonderswan color (who owns one, beats me) and not sure if KRIKzz is making more stuff. At least KRIKzz gave us a good sd2snes and a really decent NES flash cart among all the other stuff he made. Plus his N64 flash carts are incredible. Talking about Jaguar, 64-bit on N64 is quite decent and there's more than a baker's dozen of games that were great on the N64. I can think and list out 20 games usually off the top of my head so there's probably a bunch more. Nobody can list that many good titles for Jaguar lol.
