Happy New Year everyone!
A preview of something some friends and I have been working on.
The Skeleton Key ENDGAME payload contains PrometheOS, Insignia's Setup Assistant, XCAT, a controller and memory test and Rocky5's softmod, all sized down to fit on an 8MB memory unit! 1/3

Context: LoveMHz uses this as an example that PrometheOS stole parts of his code. When I asked the author, Equinox, about this he has this to say about the apparent similarity (attached).

Team Resurgent let us play around with PrometheOS. EQ gave us the base for a neat little FTPd addon for UIX Lite.

The shields were sanded and repainted, and a 500GB SSD installed alongside a Startech SATA2IDE adapter and an ASUS UDMA ribbon cable. A ModXo modchip with PrometheOS was also installed, Cerbios 3.1 in bank 1, and the UIX Lite dashboard 😊

I then proceeded to upgrade the RAM. I used an Aladdin chip with Xblat to test the installation (I wish PrometheOS would have a RAM test too!)

Next up the Topvint ModXo installation. The previous LPC rebuild had a couple of missing pins in the port, which I had to put back an resolder. The Topvint ModXo modchips come with PrometheOS and the latest Cerbios in the first bank.

But the best feature of the ModXO is that it is based on the well known RP2040 microcontroller platform, and the firmware is open sourced, making it pretty future proof! For example, you can run the #PrometheOS BIOS, which starts a web server for futher customisation, all running in your modchip!

Pandora is a means to accessing Xbins, and Xbins hosts Cerbios (a custom BIOS for og Xbox) and PrometheOS (open source firmware for Xbox modchips). MakeMHz claims these two pieces of software used parts of his code without permission.

With a Cerbios Flash you can use Drives with up to 16TB.
There are some good inexpensive internal HDMI solutions that should even help you squeeze out DTS.
If you look for a decent modchip, look for a ModXo and flash to it PrometheOS.
As a dashboard look for XBMC4Gamers or UIX Lite.

PrometheOS let's us enable RTC use and adjust the time and date. The project page says that it should last 6-10 years 😎 Customer didn't want a new HDD so I installed UIX-Lite in his existent partitioned HDD. Maybe it can hold 2 or 3 games? 🤔😂

ultimately what this allowed me to do is drop in a much larger hdd than the 10gb it came with, fill that full of games, and i'm off to the races. down the line it will also let me set up an lcd display for temperatures on the front of the case and hook up rgb lighting as well.

Also don't mind the version number it'll make sense once I get all the lore out there.

It would make sense as a kind of super advanced version of the Prometheos multi vector mode. But then again, i dont need to see them overplay that feature

Is a Raspberry Pi in there. It runs PrometheOS, which can handle multiple BIOS banks. So the software that boots the chip is different than the BIOS replacement for MS' firmware, if that makes sense. You can upload new BIOS though a web browser. Is really cool!

It's better to just brick a modchip than to brick the TSOP that is soldered onto the motherboard.
Might even replace the caps that are responsible for CPU and GPU.
This is going to be a fun "My first console repair" project for myself.
On the Modchip i plan on putting PrometheOS and Cerbios.
