So, I put this (and only this) on an SD card:
Autoexec.bat
Command2.com
MSXDOS2.sys
ReBOOT.BAT
ocm_sm.pld (from 11/26/2022)
smxflash.com
xflash.bat
And I'm going to put it in the SX2 set to 2MB and type:
A:\>SET EXPERT ON
A:\>SMXFLASH OCM_SM.PLD
Will this work good?
As long the OCM_SM.PLD is from a SX2_ folder, yes... The two important things are:
- Never use anything other than SMXFLASH, preferrably a version that came with 3.9 or 3.9.1 that have no issues with any DOS, be it MSX DOS or Nextor
- Never, ever, NEVER NEVER NEVER use a firmware that is not placed in a SX2 folder, pinouts are not compatible with SMX or other OCM_SM devices, that surely will brick your device and you will need an USB Blaster (can be a generic cheap Chinese clone) to restore it to life
Of course, this applies to SX2, for SMX, the instructions would be SMX folder... For OCM or Zemmix, those use PLDFLASH so my instructions do not apply at all 
P.s.: I recommend you just buy and have an USB BLASTER, once you have it, you do not need to fear bricking it, you can always restore it pretty quickly using altera tools 
We never expect bad things to happen, and with latest versions of smxflash you will brick it only if the power fail mid flashing or if you choose a bad PLD file, but since a BLASTER is so cheap, I recommend every OCM/SMX/SX2 owner to have one

I actually looked into this, but I kept reading that the Blasters that are available are not the "good" blaster and no one makes the "good" blaster and the ones available are clones that don't always work right. Can you link to one that is high quality?

That's something I can't help, when I've bought my SM-X prototype from Victor Trucco I've asked him to send one Blaster as well, I know it is a Chinese clone and that it works well so far, but won't be able to give you a link of a reliable source

Victor said they all use the same program now so they all should work. So, it should not be a problem finding one. On Amazon Reviews, a user said they say they are version 2, but only work in version 1 mode.
