Nice! and about FPGA implementation have you completed?
Procycon 2.0? have i missed something and there is there a 1.0 already in 'production' ?

Procyon 1.0 is the technology demonstrator. It has no video genlock and analog PLL. That part was added last year.
So, the schematics and the board will be changed. On top of that I add ARM Cortex M4 uC for DFU, SD card and other peripheral emulation (you can read a couple of pages above the detailed report). So, the version 2.0 will go into the mass production.

@maxis Cool! One 2.0 specs are closed, please share with us Wink . As far as I know, this device will convert any MSX1 into MSX2+ with HDMI output, maybe?

If you read the thread you will see that it does.

See the post page #43. There I've listed the 2.0 features.
Regarding the MSX2+ conversion, I'm investigating the compatibility when intersepting/overlaying the ROM with the patched version and VDP sitting at 0x88-0x8B addresses.

Otherwise, I'm still waiting for the license to include/modify MSX ROM

Short updade:

Schematics of the rev 2.0 is completed.

No BGA components yet (I'm questioning it all the time, however). Will stick to the 2 layers PCB. With 35 ICs, around 130 resistors and resistor assemblies and same amount of caps, hand assembly will not be the weekend project any more (never was).
