Victor Trucco announced MSX-SM

Please understand that I'm not anything other than an owner of an SM-X like you, just that I've really liked it and done and will probably still do a lot of stuff for it and for MSX in general, but all I do is free, and I do not earn a single dime on it... I'm in no way linked commercially to this project... Keeping this in mind, what I can tell you about what I THINK that I know:

1. I'm unaware of KDL taking this task as well, as SM-X is different in many respects and not just a simple OCM clone. It has different hardware around the FPGA, different connections, use different flash memory, etc... So the firmware KDL generates for OCM/Zemmix and other OCM clones DO NOT WORK ON SM-X AND SHOULD NOT BE USED. If KDL release something for SM-X he will tell that and will make sure to distinguish SM-X files from the other devices. Now, all changes KDL makes are merged into SM-X in a couple of days once a new version is released, I usually do this if I have free time, if I don't Victor or someone else will do for sure. The question about WHERE to officially get the latest releases, only Victor can tell.
2. SM-X firmware is a super-set of OCM, so it contains all functions of it and adds upon it. Regarding the DIP switches, as far as I know there is no difference but I might be wrong
3. Victor is the guy that can answer that, again... As far as I understand, other than what you find on regular OCM you have OPL3 support in VGMPLAY and a MIDI interface compatible with the one in Turbo-R, through joystick port 2, but I'm not aware about the details on how to connect it
4. As an user I agree with you and I know that Victor is very supportive of having users help (i.e.: I do this sometimes), so just tell him you are willing to and I'm sure he will be thankful
5. I'm not aware of any changes in respect to that, as far as I understand the SCC code is the same as in OCM at this moment, but I could be wrong. A simple test would be to get any enhanced versions, like Salamander, and check if the dual scc is working (voices and game sound/bmg)
6. Well, I'm always open to listen for suggestions, but keep in mind that I'm just an owner, like you, the difference is that I just had my SM-X since last year (prototype) and decided to do stuff on my own, on my free time (which is not much lol)... Regarding Victor or KDL, it is up to them to answer that... I would not get discouraged by FPGA space, in my mind, if an idea is good and needs more space, and someone do not want OPL3, you can just fork the SM-X firmware and create a variant that has a V9990 built in (just a silly example, I have no idea how many cells would be needed for that)... I really think that users helping on new stuff (like I've done with WiFi) will be the driving factor of cool customized versions (which might end-up being integrated as far as space allows and it is something that most would use).

About audio, I think that Victor goes in the same direction and he has worked really hard to have OPL3 and MIDI done before officially releasing the project, so I think that if anyone is willing to help on that department, help will be accepted, but again, this is me talking, an user that just happens to have his development upon this open platform merged in the main code, Victor is the guy that can oficially tell about all of this and give better directions on how each of those concerns are going to be addressed.

I have to say, the prospect of an FPGA MSX without the space limitations of the Cyclone 1 is very good.

Awesome, @ducasp, thank you very much for your clarifications. It sure makes it much clearer what role everyone plays on this project. And also thank you very much for all the hard work you poured into making this project even better. UNAPI Wi-Fi is awesome. I hope I get to play a little bit with it this weekend.
