No offence taken.
Some things I'd like to point out though:
- Picture quality is better than you'd expect and better than any other composite signal you've seen - I'll provide a photo to prove it (the blur on the main character and fish sprite are from them moving - should have paused it sorry).
- I would much rather play on a large CRT TV than a tiny LCD screen.
- I can also play my real MVS carts and many other jamma based arcade PCB's with this setup, it's not Neo Geo exclusive.
- Re the multicart, I use it as it's less hassle than constantly ripping out and inserting a new cart, plus aside from the hacks the games play identically to their counterparts.
- I can easily use an AES joystick.

^ Neo Geo on actual hardware via a nice CRT TV beats the crap out of Mame/Kawaks.
