* CD-i: Fixed buffer overflow
Fixed reintroduction of the buffer overflow by
commit 1addb89ff
Originally was fixed with c0171c9 but not yet
well understood.
* CD-i: Mount root folder NvRAM after core load
Instead of starting with an empty NvRAM,
"saves/CD-i/CD-i.sav" will be loaded instead.
Avoids machine reset by NvRAM change in case
a root folder CD image shall be used
