Let me present an ambitious research project that's coming together now :) It's a drive emulator unlike anything that came before! (Sorry for the video orientation, I'll do some more later) (1/2)

The crazy research experiment that started years ago is now getting real, many thanks to @Xrider_74 for the nice hardware! Physics model done, code base almost done, SIO port still WiP... Soon! :)

mStation update! I'm no video producer, and it shows, but we're happy to see that Proto 1 hardware worked out, and it demonstrated what we needed it to. Here's a bad video of the world's first "RF ODE" (I think?) starting easily on an NTSC-J machine :)

This generates a reed-solomon coded, scrambled and eight to fourteen expanded CD bitstream (to the Red Book standard) in real-time, enabling the ODE to be compatible with any CD system. It's specialized to the PSX here, where all analog functions have been implemented :)

xStation 1.6.1 is out now, a performance release :) There's many new findings in this version, leading to significantly better performance, at less resource usage. It was a bit of a rabbit hole, to be honest.. Sorry it took so long, hope you enjoy! :)

A new xStation release :) Highlights are the embedded loader, much better dealing with slow SD cards, and the Mechacon tweaks. Once HW ships with this, boards can start without any SD card (for basic trouble shooting)

Small update: Working on xStation for a while now, as there are some bugs in 2.0.2 that really needed to be addressed, and mStation work is taking too long. I hope to deliver on xStation soon'ish (DDR games, Legend of Legaia, SD card troubles) :)

The shown game exercises the (analog) seek capability, which almost took longer than the Reed Solomon to develop :p Just want to add that it's still in research overall. Please don't expect this to be ready for a while still :p

So pretty boring stuff to look at, maybe, but it's what powers this that counts. We'll be able to plug and play into every PSX, compatibility will be perfect, now we just need to reduce the part count and size of the thing, as well as doing all the pad / wifi stuff! Stay tuned!

Everyone that's using a 3D print SD card mount, please be aware of this issue! You should file down the edge a little as shown, preventing it from damaging the slot pins. The SD card standards demand a bevelled edge here (and every standard card has it).

@ShankMods All options are very difficult to begin with. A traditional (soldered) ODE needs to work in the 10+ mainboard revisions, which makes that a logistics / economic issue. A laser level (plug in) ODE needs to run at lightning speed and likely cheat to get there.

As many are aware, the earliest run of Zelda cartridges used tape for the game save, due to the shortage of low power SRAM chips at the time. This is the reason for the warning to hold RESET when powering off the NES, to give the tape time to finish winding.

There was an actual problem with the DSP used: It's the rather obscure CXD2516Q, a 100 pin version for which there doesn't seem to exist any pinouts. Figured it out anyway: lift SENS, SUBQ, SCOR and C2PO.

@8bitmods We have figured out how to emulate a full CD based system, but ramping it up to DVD is a whole other thing. DVD in the PS2 uses different maths, it's much more memory intensive and much faster. Let's see the CD emulator come to light first :)

The Raspberry Pi Pico is a great board for collecting data from several sources, then combine and print it to the USB UART at high speed. This keeps up with an external 3MBaud UART, its own data collection from the PSX decoder bus, and even an additional SUBQ line. Great stuff

@ArielAces @Xrider_74 No real advantage, it would be a sidegrade :p It does the same things at the core, which is to run CDs, but now it is able to be plugged into all console revisions and needs no soldering steps. Of course this uses beefier hardware, so some things will be nicer on it :)

@jeffqchen You are describing the RF ODE. A "next gen" ODE that can send virtual pits and lands reflection current to the console and that reacts to motor signals. It'll require a ton of research, but has the potential to be amazing :)

@HilltopWorks @mrnobodystudios @EsperKnight @Cargodin Always great to see new PSX translations! This seems to run fine on xStation / real hardware, but the patcher creates a .cue file that is named different to the tracks. XStation bases .bin/.cue sets on data track 1, so the .cue needs renaming to "Addies_Present_1.cue" :)

@FenrisRetro @Xrider_74 So the working principle is very universal, but different systems have different approaches, so that means cables and signals on those cables vary. We'll have to see what can be done to try and address this, potentially adapters and such. It just needs research = time :p

@jeffqchen What's going on: These adapters come with a pull resistor on the clock, maybe for improving some aspect of the long signal wire. The problem is that the resistor value is far too low, so the clocking chip has to work super hard. It's best to remove it.

@RileyRShard @Xrider_74 Sure, let's see: I want to avoid making too sweeping statements, but every PSX console will work with this, with the early revisions (PU-8) potentially requiring the user to tweak laser adjust pots on the board. Keeping the old drive would be something on top. We have it in mind.

@knightoftism It depends? :) For now we know how to create Red Book in real time (restartable). This is the CD bitstream, and every CD decoder understands this. The other part of a full system is the emulation of motors, magnetic coils and their feedback. This differs between systems.
