Ok just got the modchip installed, The points are very small and the modchips PCB is a little thick (which is good, and bad) It makes getting to those tiny points really tough without bridging neighboring points.
I ended up using a wired install using 30awg solid kynar wire from radioshack.

Modchip works fine, haven't had any issues so far.
A wireless install should work fine, but i found using wires to be safer to avoid bridging.

This the best chip for the gamecube! Install is very easy 6 solder points not tht hard, and what was even greater was that I didn't have to do the pot tweak it worked right after install!!! Got here fast too A+ modchip central I will be ordering a lot more from you guys again. You guys are the bomb.......

Sold me Xen8gc(knockoff) not Xenogc as pictured on the product page. Chip menu loads black and white and with static instead of stable and colorful. When i switxh region it plays in black and white with static. Price i paid: 22 dollars not 9 as mentioned. Ebay prics for xen8gc is 4 dollars rippes off: i think so

Got the "generic" (knockoff) XEN8 chip, not the real XENO chip. Shipping to Florida took a long time. I ordered on 9/18, order received 10/12. Don't expect the authentic chip from this site and be prepared to wait.
