I've updated and more or less finished the GBA version of my mp3 player!
The new GUI is fully functional, with filelist, playqueue, options, etc.
Alltogether, it's about as good as it could possibly get on a GBA console with 32Mbyte cartridge storage space.

I need some help on supporting ...

PS. The kernel clone does not have it's own font at ROM offset 64000h..7FF31h.

Instead, no$psx does automatically insert font data ripped from your harddisk (either a Windows font, or the official Sony font from your PSX-BIOS.ROM file; if you have that file).

Before sharing the kernel clone image ...

Thanks for asking! If somebody somehow makes thousands of dollars with it then I would it be actually neat to get some percentage, whatever feels reasonable. And for homebrews with few paid downloads/donations, just include it for free.

Speaking of steam, if they would be hosting a lot of console ...

Do you mean physically stolen tooling, and Cybdyn can now no longer produce their own connectors without that tooling?

On a SNES, that would be done via hardware like X-Band Modem. That is, not a simple thing, and with handcrafted time-sync patches for each game, and with the hardware supporting to automatically install those patches, but how would you do that via controller port???

And the SNES is a system with ...

From the help text:

CDROM BIOS Image
If present, file MC68HC05.ROM (16.5kbytes) is loaded automatically as CDROM
BIOS image (alternately it can be loaded manually via file menu, which treats
any 16.5Kbyte .ROM file as CDROM BIOS image). The file (is) used ONLY if low level
CDROM BIOS emulation is ...

Thanks! Having the +/-6% with 0.02% stepping specs is very good to know to get an idea how it should work. The Mode button does also sound like a useful addition.

My current GUI is simply using a text based list with 17 pitch settings. For the 0.02% example, I would need to expand that to 600 ...

Are you sure that the SDL thing works on PSX? I have never heard of PSX software that could support long filenames, or play uncompressed wav files. The traditional PSX libraries certainly can't do such things.

Hardware-wise, without libraries and SDK's, it should be all very easy, with some quality ...

Ctrl+R to reload the executable or disc image.

I have no idea what you are talking about... a tty text output hardware game that was made by someone?
But whatever you mean, I have probably already emulated that.

Ah, okay, I didn't notice that it's only showing the Side A copper layer. Nonetheless, it is additionally showing the Side A text layer (or something similar to that, it doesn't exactly match up with text layer on the photos).

Most of the horizontal, vertical, diagonal and curved lines on the ...

You can even see the connecting trace in your own photo actually if you look close enough. On both connected pairs actually.

Hmm, yes. That makes it look as if there is a horizontal wire between the upper pins of the capacitors.
I'd still use a multimeter to check if the ripped wire does really ...

Would it be viable to solder it together with C518 instead, since they seem to be connected?

I don't see what makes you think that they are connected. The picture from the service manual is kinda useless, it's showing multilayer pcb wiring, without any indication which wires connect to which ...

There are two relevant threads, albeit none with a proper thread name referring to the problem.
Now that you have created a dedicated thread name, we could keep that, but need links to the other threads...

Well yes, that is a known issue, but why do you start a new topic on that?
Use the search function to find the existing threads about ed by ed by.

That is called Texture page.
I don't remember if you can set it to 544, otherwise just use 512 and 32 to the texture coordinates themselves.
There is also that Texture window feature to add/mask bits within the texture coordinates.

The linked list DMA is broken down into small DMA-snippets for writing to the FIFO, and the CPU is running between those DMA-snippets.

So yes, CPU and GPU can work in parallel. A very large linked-list, with many tiny 1x1pixel Rects will more time away from the CPU.

The official specs are here ...

Thanks, sounds as reflow didn't help, and that new chips are needed. And if it was sold, that's fine, I just wondered what happened to it.

I've no experience with buying old chips, but it looks as if you buy them online. There are some CXD1199BQ's. And CXD1815Q seems to be available en masse. But I ...

Does the console still work with the replaced CXD1199BQ chip?
(The repair was interesting. But, as far as I remember, a few days after replacing that chip, you had mentioned eleswhere that you don't have a working SCPH-1001 cnnsole? I am a bit confused on whether it's working or not.)

And did you ...

Did you use the same disc on the the 1001 and 5501's? And was it a retail disc? And just with the standard BIOS ROM, without any expansion ROM plugged into the connector at the back of the console?

I think, normally it shouldn't 'scan' the whole disc. Or only in unusual cases, like using a patched ...
