Interact Memory Manager for booting?

[NukeTheWhales]

All I gotta say is damn, we sure had it good in the Dreamcast scene. I used to think that having a boot disk was pain in the butt, then we got self booting games and I guess I got spoiled. PC iso's are also easy as heck, so when I arrived in the PS2 scene I was more then a little discouraged. Paying $50 bucks for a mod chip plus having to wire it yourself or adding another $20 or so have it installed. Not to mention that it appears that mod chips are not even all that effective, you still have to use a gameshark to boot. Hell, if I wanted to spend cash I buy the originals and save myself the trouble. This post is not without purpose however, I prepped my PS2 to do either Cog or kife swap trick and was able to eject the tray. However, I was wondering if you have to use the Gameshark (or similiar) to perform this trick. Instead, I was trying to use (without success) the Interact memory manager which came with my 16mb memory card. It has a similiar function as the Gameshark, it loads up on its own, asks you to eject and insert the game, then press X to boot. Also, the swap tricks are a pain in the ass to perform every time you want to load a game, so I was wondering what is the best mod chip for a version 1 PS2? I'm looking for something with the least amount of hastle to boot a game, and also something that isnt a bitch to install, I am not very proficient in soldering. I'm also not in the market for a $200 mod chip, I dont intend to spend more then $50 or so. Any help for a "stupid n00b" would be apreciated...
