Victor Trucco has created one of the most advanced MSX FPGA available. The first units were shipped to users and ours arrived a few days ago in Europe.

Hardware-wise this OCM clone differs fundamentally from its original model. Although it is able to use KdL's latest firmware as the base firmware, it benefits from a larger FPGA chipset that allows more features in the design. Amazing specifications characterize this FPGA based MSX computer.

HDMI support is a long time wish in the MSX world. Even when the current solution is not supported by every modern TV, Victor is working on an update to get more resolutions working with the SM-X. Digital Audio out via HDMI would provide audiophile users unrestricted possibilities. Also the opportunity to integrate a MIDI interface via the Joystickport is new in the MSX FPGA world. A third cartridge port, a scanline generator, a turbo function plus the usual OCM and Zemmix features elevate this device to the Olympus of the produced MSX devices.

The price is 318 euros, shipping to Europe and Paypal taxes already included. Please contact Victor via Twitter or his homepage to make sure you don't miss the reservation for the second edition.

What a week! Three new MSX machines, each with its own qualities. It is a relief to experience this!
Thanks to all the makers and supporters!
For the SM-X I have provided even more photos on MSX.PICS.

It's risky to put a cartridge connector on the outside. I'm sure someone will someday put a cartridge upside down for one reason or another.

sorry for my translation "google traslate"
the truth is that I like the project a lot, that FPGA I think I could get to the turboR with music module (in the Sidewinder / a girl gives up to 1200 + 030), the problem is the R800.
I will still put it on my watchlist (the MSX deserves it), to see if KDL launches a core that gives it the missing boost.
I know that it is asking a lot, but it would help some European to acquire a manufacturing license to be able to buy it cheaper.

One question I have (and I couldn't find an answer) is: How fast can the z80 be accelerated in SMX without getting graphics corruption or any other problem? 8 mhz? 10 mhz ? More ?

The core is based on KdL's but KdL isn't responsible for it. I'm not holding my breath for R800, though. It would take a lot of FPGA space, and since you can't use R800 and Z80 at the same time anyway, a lot of FPGA space would go unused at all times. Perhaps a hybrid solution could be possible? Like a Z80 with a switch to enable support for the extra instructions and change the timing?

Currently it's 8MHz like any other FPGA-based MSX. According to Luís Luca, who worked on the Brazilian Zemmix Neo, anything faster than that would put too much pressure on the memory interface and could damage the memory chips. But SM-X may be different in that respect. Let's wait and see.

Victor has just sent me the SM-X and is still traveling from Brazil to Italy. In the current firmware, CPU and VDP are still equivalent to 1chipMSX and Zemmix Neo. But its firmware can be modified by anyone because the project is free. Surely it will take a lot of work but sooner or later it will evolve, or at least I hope so! Wink

Well KDL if you're going to have an SM-X, does that mean you're going to try some new core in it?
it would be very interesting.
As I said, there are cores of z180 (nextz80 & y80e), which with certain tweaks could do the basic functions of the R800, are you ready for the challenge?
the MSX and the SM-X need you
I think asking for the v9990 would be asking a lot, although the fpga of mysticism is that of the SM-X (I think), and an AGA, or an SNES, enters.

It hasn't arrived yet so I can't give early judgments on the future of this board.

Thanks for your answer Parn. I hope someday we can break this 8 Mhz barrier, we need a 15 or 20 mhz Z80 in a FPGA MSX. Smile

Indeed, a MSX FPGA With V9990 superimposed with V9958 in one single output would be a dream. Smile

It would be lovely to have this switchable somehow. Having double outputs (maybe one VGA and one HDMI) would be nice for extended desktops and games like Codename: Intruder.

I think that before we start running we should walk a little.Step by Step
I mean, first that is achieved (if possible), implement a TurboR, and then if there is enough space we will start thinking about v9990.
there are V9990 cartridges, but there are no turboR cartridges

With all this passion, I don't understand why you don't propose yourself to write the missing components. Wink

Frankly because I lack passion, but my knowledge is 0, so I can help little.

I believe that it isn't doable on SM-X, the HDMI encoder encodes the digital video output from fpga, and the vga output does an digital to analog conversion of the same pins, so a dual head set up is not possible as both outputs use the same output as source.

Just out of curiosity, the extra gates we have in SM-X would in theory allow for a V9990 implementation? It was said by Trucco himself that a OPL4 wouldn't be possible, but a V9990 would be possible?

I believe the main issue with V9990 in FPGA is that V9990 is far from fully understood. Yamaha's docs are very lacking and even the best emulators around don't fully implement V9990's features (as available on MSX cartridges, since V9990 itself has even more features that current cartridges don't or can't use). It's hard to even gauge how much work would be necessary.

Then again those features are not used by the software available at this moment so emulation nor FPGA implementation have to necessarily implement such features.

I'm tempted to say that there's a chance of an hybrid 9958/9990 core without removing opl3, but this is just a guess... Main issue is that you need someone to understand the current usage of 9990, perhaps knowing a bit of what OpenMSX does wouldn't hurt, and then mixing it in the vdp code...

As you can imagine, there is a lot of time required to do that, to understand ocm vdp implementation, to understand v9990 (and perhaps its emulation on OpenMSX) and then add it to vhdl... So, it is a matter of having someone willing to do it (and probably learn a lot on the whole process). Any candidates? Big smile

I'm sorry for not being clearer. I meant not even just those features used in current MSX cartridges are fully understood yet. I don't care for unavailable features, like VGA mode (although a future cartridge could have it, but let's not go there). However, I wouldn't bet on leaving out features available but not currently used, since those could be used in the future anyway and we would hit a roadblock if there isn't any more FPGA space to implement those features then.

Of course all of this is currently a pipe dream. I don't see anyone trying their hand on a V9990 in FPGA any time soon. Smile

It would be great to get them produced in Europe. Maybe Victor is willing to license them to a local manufacturer. IMHO this is the future of FPGA based MSX computer.
