Added July 24, 2019.In the second post, I'm asking for Tile graphics mode, but I split the post.
"TBBlue SD Distribution v. 1.0" (CORE 2.00.00) was announced as "GOLD EDITION" on September 25, 2018 last year.
"Sprite function" is a thing that displays 64 images of 512 colors of 16x16 size and together with "Layer 2 graphics" that can express 1 pixel with 1 byte (8 bits), it is "creative" but it is game graphics Using it as a CPU is high and requires programming skills.
The reason I wrote the "preamble" in this thread is because I got a reply that "core development has already ended" in other threads.
"The development of the core is already finished" or "the core team does not want the core to violate the IP of the manufacturer (Actually, isn't that the author now claim to be non-commercial or open source for free FPGA cores?)", TheSMoG 's remarks, I read the forum in May,2019 this year all It was deleted.
On January 27, 2019, "TBBlue SD Distribution v. 1.03"(CORE 2.00.26) was released this year. The "tile map mode" required for game graphics has been added, and improvements to the sprite function have also begun from this version.
The system card released today on July 24, 2019 changed its name from TBBlue to "System/Next"(CORE 2.00.28).
Since last month, the image of "Pentagon 128" demonstration program has been posted on official Facebook. I tried to discuss the possibilities as a "multi-core system" of ZXSpectrum Next, and posted this thread on the bulletin board of "Other Cores".
A video of a demonstration program for "Pentagon 128" is pasted on the official Facebook and a demonstration of TBBlue's "profile change function" is released.
Also, the profile of "Pentagon" has a comment that it will not work with HDMI because the vertical sync frequency will be 49 Hz. (To be exact, this upward compatible machine has a VGA or HDMI terminal and it has a 640x480@60Hz screen Will it be converted?).
And the "Across the Edge" demo by demarche.
Also, for those interested, this is over the SCART cable.David Saphier
Note that this is a Pentagon demo and uses NO Next featuresJim Bagley
The HDMI and VGA are different timings, and the Pentagon ( russian clone ) needs 48hz which HDMI won't support, so if you want to run the border and colour effect timing specific games, you will need to use a SCART cableVadim Akimov
at 4:00, it is clearly seen that not the whole visible border range of the original Pentagon machine is visible. The original Pentagon had approx. 384x304 visible screen. However, even ZX-Evo does not show the whole pentagon screen.

Although "Pentagon 128" is compatible with ZXSpectrum, it has evolved independently, and the aforementioned "demo program" adopts a "wide" resolution graphic screen.David Saphier
Normally switching between personalities has to be done via the boot menu. If you need to do this a lot, then a quicker way would be nice, so .boot! Not super special but super useful - for me anyway!
Does personality changing flash the FPGA?David Saphier
That's a good question, I believe the core is flashed to FPGA upon startup, not sure about hard reboots. Sure someone else more inclined on matter could answer that.Allen Albright
The core is not flashed... the personalities are all using the next core but have features disabled and timing changed depending on what the machine is.
There are 32 available slots to hold cores in the flash. Slot 0 is the anti-brick core that will rescue the machine if something goes wrong during a flash. Slot 1 is the zx next core and the other 30 are currently empty.
