But I do use the OpenXenium firmware. Kekule had seen my work on the PCB design and introduced me to Ryzee119 while he was still working on the firmware. In the end I had a working prototype within a few days of the initial release of the OpenXenium using my own hardware design. I use OpenSource firmware but all hardware designs are of my own. EDIT: I actually found one of the first interactions Ryzee119 and I had back in early October 2019 Should I clone the "Xenium Ice" - Page 3 - www.emuxtras.net Alot of the images in that thread are gone but some still remain on page 3 Edited June 18, 2023 by NeMesiS 3 Quote Link to comment Share on other sites More sharing options...
NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 I'm going to find myself in a similar situation with the HDMI mod. There are going to be similarities when working with existing hardware (fitment). And even more similarities when everyone's following the same datasheets (schematic). But I've been using Ryzee119's XboxHDMI for reference as there wasn't much of a datasheet for the ADV7511. https://github.com/Ryzee119/XboxHDMI-Ryzee119 I only just noticed that LoveMHz was a contributor so I'm not sure which project came first. With some small changes I don't see why Ryzee119's firmware couldn't work on a MakeMHz device with an STM32 mcu. Or vice versa... 2 Quote Link to comment Share on other sites More sharing options...
dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 Just to clarify… I wasn’t insinuating anything. I just thought since the firmware was of open sourced…. That your project also had to be open sourced. 1 Quote Link to comment Share on other sites More sharing options...

Wait a minute... are you saying that the chipset (one used in the MakeMHZ design) can be theoretically modified with firmware that you can write to allow for any bios to be used? Is there any way for him to block that without completely changing his design? 1 Quote Link to comment Share on other sites More sharing options...
dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 (edited) It’s not the board that is limiting the bios. It’s the patches that tell the Xbox how to use the hdmi board. There has only been patched for M8. (As far as I know). Other bioses could be used if someone made the patches necessary.

I wish it could be done... especially since he's already mass producing hardware that can be used with a certain bios if it's patched. (Ahem CERBIOS!!!! cough cough...) Excuse me.... Wish the already patched bioses could be reverse engineered to find the code that would make Cerbios work. I think that can only be done with source, though... Well, There's going to be HUGE demand for this hardware when you finish it. Because it's awesome. You will enable any bios to be used... Sounds like there's gonna be a line of people waiting, or people are going to have to solder them on their own if they want them... maybe it's a good time to learn to PCB solder, eh? 2 Quote Link to comment Share on other sites More sharing options...
NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 Comparing the StellarHD+ and the older XboxHD+. I immediately noticed the lack of an MCU which seems to have been relocated over to the Stellar modchip. So the HDMI mod is more of just a daughter board now and cannot operate on it's own. If you just wanted the modchip you're still paying for much of the hardware for the HDMI mod. The HDMI mod now seems even more over priced considering there's no MCU or firmware. It's not difficult to work out how much the components are worth through sites like DigiKey and Mouser. Your only really left with the ADV7511 and a bunch of other basic components. 3 1 Quote Link to comment Share on other sites More sharing options...

Is there a difference between the two HD+ units, other than Dustin making it impossible to use without Stellar and pulling an Apple move? How many units do you plan on producing anyway? Enough to cover the demand I know there will be? That's a lot of soldering if you're doing them by hand. Quote Link to comment Share on other sites More sharing options...

There's no MCU on the StellarHD+ HDMI module Thats as about as far as I looked into that. I'll keep making them so long as they keep selling. After I'm confident with final design and had some testers try it out. I'll probably start with a small batch of 100pcs. 2 Quote Link to comment Share on other sites More sharing options...

Everthing comes down to your personal skill (in the very first place) and the tools you use. Look at one of your TSOP's. If I'm not wrong those are 0.5mm pitch. Not to hard to solder under a microscope and the right tip. Quote Link to comment Share on other sites More sharing options...

dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 When you get down to it. I can test if you’d like. I have all the equipment and have already installed one . One way to help with cost is to ship all units to one US tester and have that tester ship to all others (just an idea to reach more testers) 1 Quote Link to comment Share on other sites More sharing options...

NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 (edited) Well I';ve installed a few of these for customers. There have been a couple of times where they would send me a standard black console to mod. But would swap everything to a crystal or halo console once they got it. I've been thinking doing without solder pads in exchange for connectors. So like a 3pin connector for 5v, GND and SPDIF. One side of cable gets soldered to the mobo. Alternatively I could forward 5v and GND (plus sda/scl) from the Xenium modchip, leaving only SPDIF to be connected. But then not everyone's gonna use one of my modchips. I dont think it would hurt to have 5v coming from 2 different sources as they are all the same 5v line to begin with.

Tomcat's definitely more qualified right now to install an HDMI mod. The ribbons worry me because I can't see what I'm soldering, I think. Aren't the points underneath? By the time you start testing or shipping these, I will be able to do an install. I learn fast and just haven't because I've been working... up until now. Lol. I definitely need a better Iron, though... Quote Link to comment Share on other sites More sharing options...
dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 Not familiar with 5V sources on LPC. Only concerned would be what it can source … and what type of noise the hdmi board would induce. Would think the new stellar setup would’ve done that if it was feasible (guess only). Or could be stellar pulls more current and none left over. Or simply leave as is to make switching from old to new easier Quote Link to comment Share on other sites More sharing options...

MakeMHz moves the 1.8v regulator over to the QSB board. But uses 2x 3.3v regulators on the HDMI board. Either those tiny regulators don't produce enough power on their own or it's to help with noise I'm not entirely sure why they've done that. I've been working on a 2-layer design but might go with 4-layer, keeping data traces in the center sandwiched between alotta grounding. But the consoles shielding should be enough for most external noise. I tried to boot a motherboard outside of the console without any shielding one time and I couldn't get any picture via component cable whatsoever... 1 Quote Link to comment Share on other sites More sharing options...
