I switched GR8Net and SD/Mapper, so the first was in slot 1 and the second, in slot 2. And SD/Mapper was drive A and B, and FM works. Hoorah! Big smile

Now I need to know how can I use Nestor Soriano's network utilities in GR8Net. Thanks for all help!

Is there any new updates?

Look here, usually build datecode is the same as file time stamp. If there's critical update I usually announce it through my Facebook account and in groups.

The CALL NETSETMAP is a little tricky command to master.

You just need to understand the logic. Lower nibble is mapper number (0-14), higher nibble is special reg set appearance (in standard GR8NET configurations = 16, in no-networking mode 0). Second argument is actually not needed in usual setup (GR8NET automatically detects conflicting mapper in the system and turns on/off its own port register reading appropriately). Third argument is also needed only for advanced configurations (e.g. running MG2 with GR8NET mapped RAM disable, that's why its file name contains {311} - mapper 3, expanded mode, no mapped RAM).

Later this week i will release GR8cfg, a basic tool to use most common settings of the GR8NET, without needing too much knowledge if you want to keep things simple. Smile it is non-linear and gives an average user, who doesnt want to go through a manual, the chance to use this great cartridge in a flexible way.

I started today to take a look at GR8CFG, it's a amazing tool to config GR8Net.

But I got a problem... Crying I set the GR8Net to mapper mode 7 (1 Mb mapped RAM) - call netsetmap(7), I think. Now my GR8Net is only seen as a 1 Mb expansion board. Any commands, like CALL HELP returns a Syntax Error message. All other features is gone. Eek!

Any clues? Question

Hi rjp. Thanks for the compliment. Smile
I read this part of the manual, which indicates it is normal and expected behaviour (see quote of this part of the official Gr8net manual under this post). The solution isn't clear from the manual how to return if you used it and it is set to boot by default.
Hopefully Eugeny can shed some light into the matter.

Quote:

11.6.7. Mode 7: 1 Megabyte mapped memory
To change to mapper mode 1 in BASIC please use the
following command: CALL NETSETMAP(7)
In this mode card represents its available RAM to the MSX machine as normal mapped RAM, available in all banks. Mapper is having its internal memory mapping registers at ports 0FCh-0FFh, its readability will be controlled by second argument of NETSETMAP command.
Cartridge is fully dedicated for mapped RAM operation, there’s no GR8NET ROM initialization, and no CALLNET or CALLDSK commands present, and BASIC will return Syntax error if you try using them.
If card will be the one with largest memory installed into the non-Turbo machine, its space will become main memory
for MSX. This may affect behavior of some applications and games which by default expect RAM to be in slot 3.2.

You could try holding down the Arrow Down key when booting, it might force the GR8NET into mode 0, found it somewhere in the manual.

@rjp: did it work?

Yes, this is the only way to cancel reconfiguration to the target mapper.
