I love playing Ikaruga, Chaos Field, Capcom vs. SNK 2, Metal slug Anthology on Gamecube/wii. However I hate using the controller for these types of games. I use a weird setup that works great for me, especially since I have a limited budget. I was able to get my hands on a Tekken 5 bundle, they are 29.99 now which is a steal for the Hori stick alone. Second, there are PS2 to Gamecube converters on ebay that can be bought for less than $10 with shipping included. Although the buttons take a while to learn, it does a better job of re-creating the Arcade feel of these games.

Just thought I would share this with everyone.
