The potential for HDR given the chosen HDMI retiming chip
Now that we have the open source schematic files we can see that the chosen HDMI retiming chip is the SN75DP159. This only supports up to HDMI 2.0b which limits high data rates as it only supports TMDS signals rather than FRL signals. While technically you can do 4K60 HDR on HDMI 2.0b, to get the 10 bit color required for HDR you need to do 4:2:0 chroma subsampling (though HDR for filters should be mostly luma). I think this will somewhat limit the capabilities of HDR-capable filters on the M64, though HDR should still be possible. I really wish they'd gone for a chip that supports HDMI 2.1.
Worth mentioning that this also means 4k120 is not at all supported and will not be supported. The chip only supports 18 GBPS total data rate.
Worth noting that the HDMI retimer chip is driven directly from the FPGA without any intervening circuitry which is what you want to do if you want to minimize latency. They also have very fine-grained control of the HDMI signal, at least at lower data rates (if it weren’t for the legacy HDMI timing chip that limits data rates it could likely go faster as well). Though my bet is that they're using a pre-made display port IP core (which would limit their ability to open source the code, but we'll find out soon enough).
I'm not an expert in this area by any means so I want to open this discussion up to hopefully learn from some people who understand this better than I. As I may have holes in my understanding.

UPDATE: ModRetro has responded about my sticking Pro Controller D-pads
Wanted to give everyone an update on my original post about both of my M64 Pro Controllers developing sticking/creaking D-pads after only a few hours of use.
ModRetro support has now gotten back to me and asked me to return the controllers. They’re issuing an RMA/return label, and once they receive the faulty units, the plan is to send replacements.
I was also contacted directly here on Reddit by one of ModRetro’s engineers, who had seen the video I shared of the issue. He said they haven’t been able to reproduce the sticking on the controllers they have in their office and specifically wants to get his hands on mine so they can investigate what’s happening.
I made sure to clarify with both support and the engineer that this happened independently on BOTH of my Pro Controllers. The first started creaking and physically sticking after a few hours. I switched to the second controller, and after roughly an hour of use, it began doing essentially the same thing, including getting stuck when pressing right.
So, as of right now, ModRetro is taking the issue seriously and their response has been encouraging. I think it’s only fair to give them credit for that.
I also want to keep documenting the process here since several other people reported D-pad issues in the original thread. It gives everyone a better idea of how ModRetro handles these early hardware problems and what to expect if you run into the same thing.
I’ll update again once I’ve shipped both controllers back, when ModRetro receives/inspects them, and when I get the replacements. I’m also very interested to hear what their engineering team finds when they tear into these two.
Hopefully this ends up helping them identify whatever is causing it.
I’ll keep everyone posted.

Elon Musk: "All indications from data and visual inspection suggest we have solved the heat shield problem, which is arguably the single biggest problem. That doesn't mean we won't make improvements to the heat shield; we don't see any technical obstacles to achieving full and rapid reusability."
During the Earnings Call Q&A at 58:47 :
Question: "Is the heat shield the hardest remaining problem for Starship?"
Elon: "I don't want to jinx it or anything, but I think I would consider the heat shield problem solved at this point. Now, we want to take a close look at the ship that is currently floating in the ocean, but all indications from data and our visual inspection suggest that we have solved the heat shield problem, which is arguably the single biggest problem. That doesn't mean we won't make improvements to the heat shield; of course we'll continue to make improvements to the heat shield, but I would say that we do not see any technical obstacles at this point to achieving full and rapid reusability."

Best cartridge case/protectors?
I've been getting more modretro games of late and I realized I should probably get some cases for them. Does anyone know some good high quality cases?
Requirements:
- Easy to open and close without wearing
- Latches shut so they can't pop open accidentally normally
- High quality/durable
- Easily available in the US
- Transparent to see what game is in them
- Affordable (not sure what these go for but they shouldn't cost more than $5 per case)
- Ideally easily stackable, but not a hard requirement

Launch Update & Software Roadmap
Hey everyone,
As we are about to ship, I wanted to follow up on my last post and lay out our roadmap for the first few months of updates for both the console and the controller.
Quick note on how to read this: Out of Box means it’s already on your device the moment you open it. The Day 0 Update is the first update you’ll want to grab when you set up your console. It’ll be ready and waiting for installation with a Wi-Fi Update (or USB or SD card).
P.S. iFixit guides are now up for both the console and the controller. You can also find our quick start guide here and helpful "how-to" videos over on our YouTube channel.
P.P.S. Our full open source offering will roll out as we put a ribbon on all the public facing documentation, but shipping is prioritized.
Out of Box
Below are recent updates that will be baked on the device out of the box. Not a comprehensive feature list, but items you may not have seen in reviews of pre-production units.
Console:
- Flexible Update Methods: Wi-Fi, USB, and SD card
- Extended Video Profiles: Scanlines, CRT, Clean, & Custom
- Extended Video Filters: Bloom, Deblur, and more
- Controller Support: M64 Pro Controller, 8BitDo 64, OEM N64 Controllers, and wired Hyperkin Captain+ all are ready to go
- Cartridge Compatibility: Everdrive and Summercart support
- Auto-Resolution: Automatically selects the optimal resolution (4K, 1440p, 1080p, 720p)
- Customizable LED: Adjustable console brightness
Controller:
- USB Firmware Updates
- Wired Rumble Support
- Joystick Calibration
- Windows, Linux, macOS, and Android Bluetooth® Support
Day 0 Update
The moment you power on and connect, an update will be ready for download. Key highlights:
Console:
- Stock Performance Boosts: Addresses FPS bugs in graphics heavy titles
- Plug & Play Toggle: Fixes multiplayer in Star Fox 64 and Jeopardy!
- Cartridge Compatibility: Everdrive X5 save support
- Overclocking (experimental): Choose from four performance profiles, delivering up to a 67% boost
| Setting | Boost |
|---|---|
| Off | None |
| Super | 16% |
| Ultra | 33% |
| Extreme | 50% |
| Insane | 67% |
Controller:
- Adjustable Sensitivity: Configure joystick sensitivity via hotkeys
- Improved battery life of the Controller (over 200 hours without rumble)
- Fixed several issues with the wired experience
Post-Launch Software Roadmap
Console:
Controller:
We’ll post full changelogs with every release so you know exactly what’s new. Huge thanks to everyone for the continued excitement and support.

With Playstation ending physical game sales companies like Modretro who care about physical games become all the more important
With the news today/yesterday that Sony is ending all future disc production for Playstation consoles and also closing the PS Vita and PS3 online stores it, companies like Modretro become all the more important. Companies that value physical game releases.
Personally I'm not going to ever buy a Playstation device again for the rest of my life.

How do I downgrade my game version?
I want to stay on the previous game version for now as there's a bunch of breaking changes, but there doesn't seem to be an option to do so.
