I think I know why you had issues creating proper .mcs linked files.
You need to align everything to 8192 bytes for each slot (+128 byte header).
So if it's over 16K (2 slots) then create 24K (+128 byte header) with padded data.

Check out the Memory Card file format , mainly directory frames,
bytes ...

I added support for a couple of the boards I had laying around on my table (eg. ESP8266, ESP32, etc..) but probably even more boards are supported as I'm using SPI library now instead of Atmega specific ports.

Check first post for more info.

@L10N37: As you have discovered yourself everything is ...

Thank you. It's my baby, my Alfa 156.

Yup, works normally now. Thanks.

Nope, it just won't go. I tried on desktop and mobile, safari and chrome. I even outright downloaded your avatar Shadow and I can't set it.
I actually remember I had this problem way back also but I didn't bother so I was stuck on the same avatar for so long...

Yup, https://github.com/ShendoXT/padtest. Feel free to use whatever part of code you desire.

Yup, it says "Could not upload avatar to ./images/avatars/upload/32796c757064e007509b9735d1d0b92d_91.png.".

I updated the app and added Mouse support. I also updated pad routines to resemble
the way BIOS does it which was needed to get mouse working properly.

Doing so may have fixed your problem too so try this release to see if the controller works properly now.

I don't know if it's just me but no matter what image I try to upload it always fails to set it as avatar.
I can only use preset avatars. I've tried 150x150 and smaller pngs, jpgs.

This is awesome. While it's not that hard to add a serial port to PSOne, not having to open it makes this so much more awesome. Great job

If you attach ESP8266 to it you could even get PSOne to Internet through the controller port

Hi. That's not my image but I guess that's voltage divider, it's not connected to those pins but rather to GND and VCC.

But actually Memory Cards are 3.3 (3.6) voltage devices so 3.3V microcontrollers are recommended.

You can use 5V microcontrollers with voltage regulator (or voltage divider) but ...

I pretty much can't at the moment. In order to keep the code as small as possible I am not using the official libraries and afaik VSync isn't present as a BIOS call. Correct me if I'm wrong, please.

No need to use BIOS calls. Interrupt register is memory mapped,
you can read and acknowledge it ...

Excellent work LameGuy64, very impressive
I really appreciate that you shared the source for your SDK on GitHub.

No I haven't. It's under "Download and install toolchain" section.
But you have to scroll to reveal the entire code, maybe that's throwing you off...

Yes, however that repo is outdated. The newest PSXSDK is 20180115.
I could make a new repository with the current version but there are two problems with that approach.

1. It's not my project,
2. If Tails keeps updating his SDK then we will have code discrepancy.

So I would really like to have an ...

Thanks. Yeah, it's a pain sometimes to get everything working.

I actually also wanted to add macOS to the list but I'm having trouble compiling PSXSDK's tools for the host OS.
Compiler seems to be stricter and what would otherwise be warnings it treats as errors.
But it's OK, those errors/warnings ...

I updated the guide. Now for both Windows and Linux (Ubuntu) and with the latest binutils and gcc.

Was it you who jumped all those fuses or did you get it in that shape? What a mess... :(
Fuses blow for a reason. You need to remove all those wires and reinstall working fuses.

And it looks like you jumped a capacitor in one of the images.
Might just be the thing that is killing (killed) it as ...

I have been following the news around PlayStation Classic and it seems like hardware is of good quality but software is shoddy (PCSX ReARMed, lack of options, slower PAL titles, crappy interface, etc).

Once it's hacked I believe it will be a pretty neat system to own.
Would be cool to have ...

I analyzed differences between my dumper and NexTro and came to conclusion that it's related to _96_init()
function which initializes CD-ROM system and is called by the PSXSDK's PSX_Init().

In newer versions of SDK Tails92 added PSX_InitEx() which allows coder to specify various flags,
one of them ...
