Can I load a MSX1 MegaROM game (i.e. Nemesis) from Nextor (SD card will have ROMs organized in directories) on a msx1 without mapper using this version of MFR?

Yes, but you will need the version with 512K RAM in order to user Nextor.

And what about a bigger game, like Portuguese version of Shalom (bigger than 256k, I use a 512k file but it is probably "padded" to work properly with rom loaders)?

Yes, it should work.

Hi guillian
Did you read about epsg card, the project to double the 3 voices OF PSG to have a stereo sound or a multitrack pt3 player etc.
YouR MFRSCCSD gas a builtin PSG. Can we obtain same results with msx PSG and mfrsccsd PSG working together?

Regards

Darky is a more powerfull PSG device. MFR SD can be used to get 6 PSG channels (example). But it can not offer the same features of Darky.

Cool anyway.
Which player to USe?
Where to find 6channel pt3?
How to USS both PSG?

Thanks in advance

Hi,

Apologies if this is not asked but I could not find an answer and the search is not helping me....

1) How to mad legacy drives?

Details: In my NMS 8255 I have two floppy drives. As default, the A: -drive will be added after all drives mapped by Nextor automatically (either C: or D: depending on how many SD cards I have inserted). I can map another partition over them, but can not re-map A: without a reboot, or map B: at all. Is this possible? I can't figure out what to type for mapdrv.com...

2) I can not add partitions to an existing partition scheme

Details: I have added two 16MB partitions. I was about to add more, but with fdisk, there is no option to add partitions - only to display them and delete all? So it is not possible to add partitions afterwards?

3) How to mount disk images / enable dsk emulation without MultiMente

Details: MultiMente is nice, but I prefer to work in DOS ;-)

4) Is it possible to just remove the read-only romdisk (I have already replaced it) and have the A: drive as a R-W drive (on SD card)?

2) Indeed. Back up all your files, repartition, and copy them back. Your drive will be defragmented for free ;p.

3) Read the MegaFlashROM SCC+ SD manual, “[DSK new]” and “[DSK–flashing method-]” sections.

4) Read the MegaFlashROM SCC+ SD manual, “[RECOVERY]” section, “Erase ROM disk” option. Be sure to copy the NEXTOR.SYS and COMMAND2.COM files to your SD card first so it can boot from it. Probably best to copy the entire contents of the ROM disk.

Also I recommend to read the Nextor manual.

From Nextor user guide:

Quote:

If “d” is specified instead of a partition number, then the drive will be mapped to its default state, which can be one of the following:
● If the drive was unmapped at boot time, then it is left unmapped.
● If at boot time the drive was assigned to a MSX-DOS driver unit, or to a Nextor drive-based unit, then it is mapped to the same unit.

MAPDRV drive: d

With this tool it is not possible to add new partitions to an already partitioned device. All existing partitions must be removed before defining new partitions.

Mount a DSK on drive G
MAPDRV G: TOOLS.DSK

Disk emulation:
EMUFILE file1.dsk file2.dsk file3.dsk

Yes, delete it from recovery using F3

I have already read this, I already know how to flash disk images as ROM disk... but the solution for what I want was staring me at the face all the time. Guillians response helped me to notice it!

I will try this. I was thinking it could be this easy, but it is not apparent from the documentation what happens if the ROM disk does not exist - i.e. will MFRSCCSD+ try to load an partition from the SD card, or just fail. In case of failure, I could of course just flash another ROM disk but that could be a little bit of a hassle :)

This does not achieve what I want. If I type:
mapdrv A: d
A: is left as it was at boot time - i.e. as ROMDISK in my current configuration.

At boot time, I only got the first (real / physical floppy drive connected to NMS8250 MB) as drive C:. Not real physical second drive (i.e. the one that will be without MFRSDSCC+ inserted mapped as drive B: by MSX BIOS) is not mapped at all.

The physical drives (or the absence of them) is not a big deal, however - I can live without them :). I was assuming that either there is a way to map other drives (not on the MFRSCC+SD) at will, or that no one cares about them and only one of them is accessible as drive C: (even if there are more on the system).

I can restore drive C: as the physical floppy drive with "mapdrv C: d", however.

Thanks, this works like a charm! Again, I was sloppy at reading the documentation.

Guillian wrote:

EMUFILE file1.dsk file2.dsk file3.dsk

I will try this! I was looking at the listing of .COM files but didn't know what to look for.

Thanks for your help! I'm sorry if I'm asking things already in the documentation, I know it can be annoying :x

Before erasing the ROM disk, copy its content to the SD card as Graw said if you want boot into Nextor/Multimente.

Sorry, I understod you wanted to remap the disk drive after mapping a SD partition on it.

If you want to use the second disk drive, try holding CTRL while booting.

Quote:

Starting at version 2.1 alpha 2, the following changes apply to the boot keys:

- CTRL: Enable the virtual second floppy disk drive. Not pressing the key will disable it. That is, the meaning of the CTRL key for floppy disk drives is reversed relative to how MSX-DOS works.

@Guillian You mean there are a version of MFR with both (Mega)FlashROM (to run MegaROM cartridge games) and another 512K Mapper RAM in an internal subslot? That's make a lot of sense.

Yes, MFR SD can be configured with 1 or 2 SD card slots, and with or without 512K RAM.
The cartridge works as a slot expander with different devices connected (recovery, MFR SCC+, 512K RAM, Nextor/SD interface)
