Play backups, imports, and homebrew for ALL models of PS2, via memory card

[misfire]

Can you tell me more about the GateCrasher?

With Memento, I'm sure the secret lies in the innards of the PS2 player update ELF. I'm not sure if they actually simulate MG (using hardware). AFAIK, EEUG was able to run code from an ordinary memory card using software only.

Have you heard that Sony might be headed toward something called OpenMG?

Here's what I have on the GateCrasher: http://gshi.org/wiki/index.php/AR_Max_Memory_card

Also... OpenMG is pretty much totally unrelated. It's meant as a licensable DRM system, rather than a way to vaguely secure nonvolatile storage...
