I do not encourage the use of slide cards. It can damage the PS2. If you have a v7 console you can get a DUo chip or a Apple Pro for 19.99 +install. If you cannot install the chip yourself then Spedmetal of
www.norcalmods.com is up to the task and is reasonably priced. This is the best advise i can give you. This along with Ritek media and Recordnowmax.
