I've been working on modifying the RetroStone screen. I replaced it with a 3.5in IPS LCD with an HDMI input. Here is a link to a short video (work in progress):

Yes... this is cool, I notice the scren is slightly smaller than the stock screen, this should not be hard to do at all Very interesting indeed

How easy was it to do this mod, do you have anymore details about it?

Hi Ruffnuts,
The screen is a 3.5in Waveshare HDMI IPS LCD.
https://www.waveshare.com/3.5inch-rpi-lcd-a.htm
It is not exactly 4:3, it is a bit wider so not a perfect fit. This mod is a work in progress, I needed to remove the RJ45 jack and some of the USB ports to make room. I am using a WIFI USB dongle for network, there is most likely room to put back some of the other USB ports if I need to. The four holes on the left that show power and battery level are currently blocked, but I think I can make them work again.
The screen is powered from a 5V source that is on the RetroStone PCB. I still need to monitor how much power it draws.
This mod so far has been difficult. I had to remove the screen from it's control board and cutdown the control board to make it fit. I also had to cut away some plastic to make the screen fit, it is a bit wider then the stock screen. Once the screen was removed from the control board, I had to extend a flat ribbon cable to get it to reach again. I replaced the small heatsink on the RetroStone and the display with larger copper heatsinks.
The biggest problem is heat, I need to leave the system on for a while and monitor the heat load. I do not want to install a fan.
