Playsoniq: I don't get how it works really.

Okay, so I read the online manual of this new multiexpander cartridge Playsoniq, but I must say it leaves many question of how it really works. Maybe I'm not technically skilled enough or maybe it makes much more sense once you have the cartridge. Anyway here's some questions regarding the cartridge I just couldn't figure out. I've also sent mail to SuperSoniq concerning some of these (a week ago), but they don't seem to be able to answer at the moment:

1. The Video/auido output:
Okay, so the cartridge have a VGA connector which send both video and audio signal. When connecting the MSX with the cartridge. Should the computer only send vidoe/audio through the cartridge or do you need two sets of monitors to operate the Playsoniq? I found this video online, where someone first load the MSX to a monitor and then when starting a game thorugh the Playsoniq and it transfers to a second monitor. Does this mean the cartridge sends one output and the MSX another one oO

2. FM Pak:
Does the cartridge have FM-pak sound in itself or am I suppose to use the Playsoniq together with a FM pak-cartridge?

3. Modluon compatibility.
In the manual is says that the PLaysoniq is not compabitle with cartridge expanders, but does this mean it can't be inserted to the Modulon? Or was the Modulon created after the manual, so its sort of a typo?

4. Loading games. From where?
I get that the main program to start games is sega.bas which you enter through BASIC, but once you start the program, from where do you load the ROM or DSK file. Does the cartridge have a built in Loadrom-like program? And since it do not have any SD-card interface like MFR, from where do you load the game? The manual tells me to type the game name but from where is the game loaded, do I need an additional cartridge like MFR or Canivore 2 to load the game or is the sega.bas simply sort of a DOS-program?

thanks in advanace /Sid

1. You need either two monitors or a SCART switch.

2. It does not offer MSX-MUSIC (FM-PAC) sound. It refers to the automatic rewriting of I/O that it does. For the Japanese master system game ROMs that support OPLL, it will rewrite the OPLL I/O to the ports used on MSX. However you still need MSX-MUSIC built-in the MSX itself or as a cartridge for it to function.

3. The Playsoniq is internally expanded and since expanders can’t be nested, it does not fully function in an expander. However I think if you do put it in an expander, you simply get 4 MB RAM instead of 16MB, it uses only one of the internal slots. Pretty sure that works (as-in I’ve done it). Though I haven’t tried SMS ROM loading, I think it depends on which of the four internal slots is used.

4. It loads the master system games into its own internal RAM, which is then switched to read-only mode to simulate ROM, and all I/O is auto-translated by the FPGA to use MSX-compatible I/O (a pretty clever idea btw). The game can be loaded from disk or SD cartridge.

Many thanks for the answers.

Okay so If i have a ROM or SMS-file on a diskette, I will simply start sega.bas and use i like MSX-DOS, typing A: and then type the rom- or SMS-name (like if it were a startgam.com-file) and the game will be loaded into the RAM on the cartridge?
