Does anyone know if Technobytes are producing a new batch of the Powergraph Light carts?

I've managed to get in on an Amstrad CPC V9990 order with them, but all queries to establish whether they are actually doing another MSX run have gone unanswered.

They will probably produce a new batch, but only when they solve the outstanding issues with international shipping. As far as I know, those are finally settling down and I'm fairly sure Tecnobytes will make another public announcement soon.

It sounds like a V9990 decap is needed, if the design documents never were made public. That's definitely an expensive and labor-intensive multiyear project of course. But at least there are people with that kind of equipment, expertise and the will to preserve such pieces of hardware history. Like this guy or the people working on Mame.

Absent reverse engineering based on a decap (which seems daunting to me), a comprehensive research project involving a large suite of test programs and captures with a logic analyzer will go a long way.

Who is going to pay for that? :P

Such projects are usually paid by donations I think.

I think reverse engineering without the decap is typically done as much as possible, but the decap may be necessary to fill some holes to figure out the exact timing of certain internal things or other such details. Besides I think decap documents is good for history preservation reasons, whether or not anyone are willing to trace out and document every single part of it.

Dear MSX3 potential users,
I have decided to include V9990 functions into new video for MSX3. It will look like 9958+9990 and 2K support.
Best regards,
