According to the datasheet cited, the final string on the chip marking is coded as follows:

ABCXXXXXX DEFG

ABC:    Subcontractor Code
XXXXXX: Die Lot No#
DEFG:   Date Code

Given this, we have the following info about the SoC present in the sample unit:

The chip can be temporarily disabled by shorting CLK (Pin 6) to ground like so:

A pair of tweezers bridges the second pin from the bottom out of four on the right side of the Winbond SPI to the ground trace that runs around the mainboard.

RAM

Silkscreened Model Number

Transcription of silkscreened model information:

GBX107-V1.3
2022-12-23

Another Model Number, this time on a sticker

Transcription of the information on the sticker:

GBX107-V1.3
CXPOHS23098
2023-07-03

An observation one may make here is that the board’s silkscreened date is roughly six and a half months before the date on the sticker.

There’s no documentation for this online, so what’s here is what has simply been observed in passing. As seen in captured dmesg output, the kernel for this system was compiled by user sunchip on sunchip-PowerEdge-R740. Searching for sunchip rockchip points to a company Shenzhen Sunchip Technology Co., Ltd as being a possible manufacturer. Sunchip manufactures boards for plenty of systems, mostly using Rockchip SoCs. Boards created by Sunchip bear a good resemblance to the one present in the Gamestation Pro.

Looking for other boards with similar model information, one may stumble across some Arcade1Up boards. Looking into u/BerryBerrySneaky’s post on r/Arcade1Up, one may notice that Generation 5a uses the same Rockchip RK3032 SoC and carries the model number GBX70-V01. The board is also visually similar to what’s shipped in the Gamestation Pro.
