Kiddy Ride Trans Dakar II, HITBOX3 system (Game Plus Co., Ltd)

[urbanstrike]

Hi all,
I have an old video game machine: trans dakar II (falgas).

Main board: "New HITBOX3 ver 1.10", Game Plus Co., Ltd, Korea.
As far as I understand, this board and game belongs to a Korean company igameplus.com (archive.org, site last worked in 2013 year).
Problem: game loading freezes.

EDIT:
flash memory (nand) is located on the back of the board;
at the moment the system no longer boots at power on (display: no signal)

Did you try the simple stuff like checking battery, power supply etc. ?
Maybe the blue connector near the top could be a TTL serial port?

Of course, I checked the battery and voltage of all the chips on the board according to their datasheets.
I also successfully read and dumped cpld and winbond.
Also, I made a nand flash memory dump, but unfortunately I could not mount to get the files from there.
The file system or bootloader may have been corrupted. Therefore, I will try to connect to the Vrender chip.
The blue connector at the top refers to the rs232, its pins go in parallel to the external db9 and max232 connectors nearby.
And it seems to me that this is only an input for additional equipment. I already tried to connect to rx/tx, nothing..
(I have read in other Magic Eyes datasheets that the chip needs to be switched to test mode in order to be able to use uart)
