Noticed one more thing today when playing some SCC games like Kings Vally II and Space Manbow

1) SX-1Mini+ with MFR...
Game selected in MFR menu.
No SCC sound, only the crappy normal sound.

2) SX-1Mini+ without the MFR, and set to Internal MEGASCC+ (jumper 4 ON)...
Game run from SD card using SofaRom.
SCC sound is present and sound wonderful.

3) Real MSX (Sony HB-F700P modified to MSX2+, and a Philips NMS-8250 with extra memory) with MFR...
Game selected in MFR menu.
SCC sound is present and sound wonderful.

I'm loosing my mind here...

Just to make sure, have you tried increasing the volume of scc when using with sx-1mini+ ? (Can't remember which key on the keyboard)

Do this experiment: enter MSX-DOS2 with the MFR inserted in the same conditions as the test, start the A:\> SETAUDIO /S command and then load an SCC game (start it without pressing the hardware reset).

You should hear the sound of the SCC on the left side and the internal sounds on the right side. This function is called Pseudo Stereo and disconnects the audio line of the slot from the internal sounds. If it works, it means you have an audio mixer resistive sizing issue on the SX-1 Mini+.

The SETAUDIO command is inside the OCM-EXTRA Pack.

Didn't touch the volume, but does that matter if it works fine without the MFR ?
Should be the same right ?

The internal volume cannot adjust the volume of the cartridges. The volume of the cartridges is regulated by the resistors on the pcb, so do the test I recommended, you should be able to hear the sound of MFR on the left side.

I've decided to use the SX-1 Mini+ without the MFR.
I now use SofaRun to select the games, and modified the settings a bit so that I only see the games and not the rest of the files.
I wanted the perfectly made multi-game menu of the MFR, but SofaRun will have to do for now...
(until I made my own menu or find a program to make a menu)

Even though the SX-1 Mini+ is a beautifully made machine, I must say that I'm a little bit disappointed.
Not because it doesn't want to work properly with my MFR, but more the fact that some games won't work that do work on a real MSX, meaning it's not really 100% compatible as stated in the specifications.

Thank you all for your support !!

It is indicated 100% compatible because this compatibility can arrive over time thanks to the updates that are produced continuously. Have faith!

Hey SkalTura, when you added the capacitor to the USB 5V, do you know if that brought the 12V cartridge lines down to 12V even? I'm getting some gnarly clipping with an SFG clone cartridge on the SX-1 Mini+ and I'm wondering if it's because it's being fed too much power. And when you added it, was it the positive leg to the leftmost pin with the USB connector facing you and the negative leg to the rightmost?

also re:compatibility, I had some trouble with a handful of games with Sofarun that I managed to load with MGLOCM if that helps with compatibility, even for disk-based games converted with DSK2ROM which was a pleasant suprise
