cen64/device/cart_db.c
Christopher Bonhage 6b7c2af8d4 Add support for 768Kbit SRAM save type 
Fixes a Segfault when loading Dezaemon 3D.

  * Unfortunately, Dezaemon 3D does not actually work yet. It appears to
    fail the SRAM test, which still needs further investigation.

Adds an option alias for sram256k to disambiguate with new sram768k option.
