Impossible run Nextor-DOS and Nestor BASIC on MSX core

[desUBIKado]

The members of the Spanish telegram group of the MiST have tried during the past months to run Nextor-DOS and Nestor BASIC in the MSX core.

We have made it work in ZX-DOS, UnAmiga or MiSTer, but not in MiST.

We believe that the problem is in the access to the SD or to the MSX.VHD file through the ARM chip

Has anyone succeeded in running Nextor-DOS and Nestor BASIC on the MiST?

Why all this? To run MSX1PACK 2.0 on the MiST

What's the difference between accessing the ordinary BIOS and this one?

What's the difference between accessing the ordinary BIOS and this one?

Nextor-DOS 2.10 provides the MAPDRV command, and be used as a command from the MSX-DOS as within the BASIC. This command allows you to mount .DSK files as disk drives. This allows enter inside of 133 .DSK files of the MSXMANIA compilation and launching the games individually.

In addition, NEXTOR-DOS 2.10 provides another very useful command, EMUFILE, which allows you to create a copy of a floppy disk image and boot the computer with it. This allows to execute games that are in images of protected diskettes, something that sometimes does not work in other utilities like the SRI of SofaRun.

Both MAPDRV and EMUFILE are used profusely in the MSX1PACK 2.0 application that allows you to run almost 1,500 MSX1 games.

I thought about what's the difference of _loading_ the ordinary BIOS and the Nextor one? The core definitely doesn't know about what type of BIOS do you want to load. So either it's written wrongly on the FAT FS of the .vhd file (as I know that the BIOS loader is very picky), or it starts, but hangs on something.

This msx.vhd image with Nextor and MSX1PACK 2.0 works well on MiSTer but not on MiST.

Sorry, I can't say more, I'm a simple user.

It boots for me into Nextor BASIC version 2.10

[desUBIKado]

OK, but that's wrong. If was all correct, the system must boot on MSX-DOS and launch AUTOEXEC.BAT. But don't boot on disk, and BASIC appears.

You can type FILES in BASIC and you see "Bad drive name" error. Don't works "CALL SYSTEM" to go to MSX-DOS.

That same disk image works correctly on MiSTer and starts the MSX1PACK 2.0 application.

I see now. The sd_card wrapper doesn't implement the multiple blocks read/write commands, and Nextor uses them (even for 1 block access). Will add support sooner or later.

What great news you discovered where the error was! There is another great application that did not work well due to errors in disk reading, SymbOS. It would be great if the same solution also worked to work properly. Thank you very much Slingshot.

thanks for the help

Thank you!

Thanks

Wonderful. I thought the solution would be a change in firmware, not in the core, I don't know why. Thank you very much Slingshot, now many people can enjoy the MSX1PACK 2.0 on the MiST / Mistica FPGA16 too.

Thanks a lot !
With this enhancement it's pure diversion

Yesterday Invertigo and I released MSX1PACK 3.0. I made a msx.vhd for MiST / Mistica FPGA16 in case anyone is interested in trying it with the latest MSX2+ core.

MSX.VHD-MiST-MSX1PACK_3.0.7z

Instructions and much more here (in spanish, but there is a integrated translator in forum)

Works very well on MiST, good work
