C64 Cartridge disassembly?

Strange question, but does anyone know how to get a C64 cartridge case apart without breaking it? I have a bad "Epyx Fast Load" cartridge, and need a case for my "MMC Replay" w/RR-Net. I still haven't really had time to do much with the MMC Replay, I have managed to get a few things to run from it (the C1541 emulation is pretty bad). I have managed to successfully get a DHCP lease for the RR-Net, but haven't gotten it to talk to anything. I finally got some of my floppies back out of storage (put them up on accident just before I bought the MMC Replay, and I want to see about making and writing out D64 images. Zane -- | Zane H.
