Use generic portable console LCD screen on a DIY project?

So I was wondering... there is this device on sale online and I thought it would give a nice raspberry pi project:

But I wanted to check here first if anyone know about some type of microcontroller for the device' screen. Since it's a generic video game console and I'd like use a raspberry pi with its screen, it means that I'd have to discard the original circuit and use one that could convert a hdmi signal to be displayed on the screen, it would obviously have to feed the screen, with a power supply, too.

In shortly, I'm just wondering if there's a way to connect a raspberry pi to this device screen.

Specs
Brand name: albabkc
Resolution: 960x480

There are others too, like:
MIYOO MINI V2 and Nova X20mini handheld.

EDITED: As requested, here are the links of the consoles that I'm talking about:

For about $20 you can buy an LCD screen that's compatible with Arduino and/or Pi. Converting from HDMI to LCD will cost more, more than a complete used LCD TV or monitor.
Now, that handheld game console is probably running something like Linux, so there may be Rx/Tx pins to connect over serial. I can't be bothered to watch the video and see if gets into stuff like that.

It's not just the screen that interests me, the housing too, as I need both the screen and the housing for the project. And judging by the size of the screen, it's way cheaper to just buy this console and then try using a raspberry pi inside. I just need a way to connect the raspberry pi to the screen. Take a look at the video, it's a short video and you can skip to the parts that will interest you. There's a part where he says that the TFT display is a generic LCD display. If that's a generic LCD display, there must be a microcontroller somewhere for it, or a pcb to directly connect the raspberry pi through GPIO, or at least a datasheet/service manual for the screen.

There is no telling whether the display has a standard interface or is directly controlled by a custom single chip micro. If it is the latter, there is not much hope for using it.

Yeah you're right. I was just hopping that I could find some info here. Anyway, it will be cheaper for me even if I just "recycle" the housing, because I found the entire device, brand new, for $8.67 on sale. As for the firmware, it really needs to be something with a raspberry pi zero, that's just not a gaming console, it's also a cryptocurrency wallet, and I he firmware only works with the raspberry pi as far as I know.

Utilize the housing and sell the rest.
