Sorry, please read "public release" (final = not alpha, not beta, not rc).
However with regards to the release date I hope to do so by 16th Dec 2019 or at most for Xmas. Santa

In addition, Dual-EPBIOS can be set to have MSX2+ and MSXtR on the same machine or other combinations as you wish.
I stress for everyone that Dual-EPBIOS is only for SM-X and DE boards with at least EPCS16.
1chipMSX and Zemmix Neo are NOT able to do this function.

VGA output problems have been discussed for a long time and change for each monitor, have you compared with an old crt monitor? Anyway the VGARATIO.COM from OCM-EXTRA Pack can solve this issue with some LED Display or TV, but you need a bit of luck and a quality monitor with a very accurate image control circuit.

@HRAI, I'm curious. Do you have a roadmap for S1990 that you could share with us? Or at least a bullet list of features you intend do implement?

I would like to implement up to the level where turboR software works, and V9990clone if possible.
However, it is only a goal and I do not know if it can be realized.

In addition, we will make minor corrections to improve compatibility with actual machines.

I still wonder how we can purchase DEOCM from outside Japan? Because these are nice developments and I would love to try it out with DEOCM. Maybe we can arrange a group buy? Or try to find a European manufacturer, but I don’t know if the DEOCM is available for licensing to European production? Is anybody else from EU interested? Is there a way to contact the seller/producer, preferably in English via email?

DEOCM is probably only for sale in Japan.
However, DEOCM is a clone of caro's device and the circuit diagram is also available.

Also, emsxcv-yyyymmdd works with DE0CV alone.
The DEOCM board is an optional board that adds a cartridge slot, Joystick port, audio output port, and CMT output port to DE0 / DE0CV.

The DEOCM board does not supply +/- 12V to the cartridge slot. If necessary, additional parts must be installed.

I'm not sure if it will accept purchases from outside of Japan, but I will inform you of the Japanese sales site.
