No CMOS emulation on MSX1 / CMOS on/off on MSX2

[atarulum]

I found that most of MSX emulator emulates CMOS absolutely on MSX1/2 or higher mode.

But no MSX1 machine doesn't have CMOS battery.
That means, CMOS emulation must be excluded on MSX1 machine.

Also CMOS is default on MSX2 or higher.
That is correct.

But a few of real MSX2 machine supplies the CMOS batterly power without
integrated battery on MSX2 machine.
That means, if the batter energy is exhaused, a few of MSX2 software
show the message about this warning.

I'll attach this for example soon.

For example, you had better add the following on CONFIG.INI

[CMOS]
CMOS=on (or off) -- off for MSX1 machine, default is on.
Battery=on (or off) -- off for none CMOS battery Power, default is on.

That's an interesting suggestion.

When you quit blueMSX, the emulator saves automatically files in the sram subdirectory : a sram file if the SRAM has been used in the last played game and a cmos file that, effectively, has no sense on a MSX 1.

Your solution seems me good with the following default values :

- for MSX 1 :

[CMOS]
CMOS=no
Battery=no

- for MSX 2 and higher

[CMOS]
CMOS=on
Battery=on

The values could only be changed for the MSX2 configs

If I don't get me wrong, a "cartridge"-battery was also sold in Japan, but I have never seen it
