Hi, i just received my SX-1 and want to test some MSX2+ DSK games.
I thought using EMUFILE.COM would work, but unfortunately to no avail, getting a 'This programm is for Nextor Only.' error
This is because the SX-1 is using the MSX-DOS version 2.31 kernel.
By renaming NEXTOR.SYS to MSXDOS.SYS i got Nextor to boot on the SX-1.

Is there a way to flash the Nextor Kernel in to the SX-1 ?, so i can use a Native Nextor with EMUFILE.COM... ?

Hi, you need to use the sdcreate.cmd in the Extra Pack and make sure the Nextor kernel (n34 variants) OCM-BIOS.DAT ends up on the SD card. This will be loaded by the software in the FPGA and then booted. You will then have the Nextor kernel (which will boot NEXTOR.SYS).

Thanks for your help, only one queston tho,

◦ Standalone ROM with ASCII 16 mapper:
◦ Standalone ROM with ASCII 8 mapper:

Hi. You need the OCM-SDBIOS Pack not the OCM-EXTRA Pack, send me an email in pvt.

What version of EMUFILE do i use with Nextor kernal 2.1.0... version 3/2019 or 2/2015 ?
Do i have to hold the '1' Key while the SX-1 is booting for the DSK image to load ?
NEXT_DSK.DAT is only 80k, is that normal ?
