Ah, I thought it was only one "TIM" file, and might exceed 2Mbyte after decrompression. Thanks for changing rar to zip. The tim's in there have all wrong colors, which is somewhat impossible for 16bit direct color. I'd assume that they are 4bit or 8bit (or a mixup thereof). The required pa...

That is a rar file, those are very hard to deal with, you would probably need the newest version of the rar software. But even then, given the size, what makes you think that it could contain a tim file???

Look at the file headers, just having the extension is a bit meaningless. .SFX is supposedly short for Sound Effects and could mean anything. There might be some standard used in several games. But I am also sure that several people have used the abbreviation for different file formats. .SGG files a...

The "ed by ed" issue seems to be popular on reddit http://www.google.com/search?q=psx+%22ed+by+ed%22+site:www.reddit.com I don't really understand how to browse that webpage... from what I can see, the problem occurs on both PAL and NTSC consoles (despite of the different GUIs), and they d...

The boot screen where it is saying "d" and "d" without PS logo, is that because you forgot to include the licence/logo sectors, or is it a hardware glitch (that also happens on retail discs)? And the game engine, are you writing own GTE code, creating your own linked lists, and d...

My oldest SCPH-1002 is now also saying "ed by ed by" instead of "Licensed by" when booting from CDROM. That is, when booting with the built-in BIOS, it does look exactly as in the first picture in first post above, and refuses to boot any further. Cleaning the lens and disc doesn...

Just following up to say a big thank you - this writeup on the ADSR behavior is great - really straightforward compared to most other things I'd seen. Yipieh. I guess it was almost a bit too straightforward, lacking all those expected confusing descriptions ; ) I'm looking forward to your SPU test ...

The formula is A = B * C, but I don't know if or how you can implement that ; )

Yes, KM62V256CL6-7L should be the same. I'll add that as another known chip in psxspx. The XA-ADPCM decoder chip would be CXD1815Q (Decoder/FIFO), but I don't know if/which/if any pins could cause ADPCM problems. I would rather not mess with that chip, or first check the CXD1815Q (or CXD1199AQ) data...

And rougly related: The GPU FIFO behaviour. The FIFO itself isn't so special, but the timings for removing and processing data from FIFO are quite complicated... The GPU uses a 16-word (64-byte) write FIFO for sending commands and parameters (and VRAM data) from CPU to GPU. FIFO Overrun Internally, ...

Does this require much specialized hardware or knowledge? No, nothing special (other than having a way to run EXE files on the console, preferably without burning CDRs for each test). I've been reading the SPU section of psx-spx a ton over the last few days, but I haven't seen anything specifically...

Here are the GPU rendering timings. All values are measured in 33MHz CPU clock cycles. The GPU can render up to 66 million pixels per second, that figure applies for monochrome Rects, textured Rects, and even for Rects with texture blending. Monochrome Polygons can also reach 66Mpix/s, however, the ...

The best method is to emulate the SPU on the playstation itself. And then capture the real hardware's waveforms (from reverb buffer, or from the SPU status registers), and compare them against the emulated waveforms. A basic test would be to display the captured & emulated waveforms on the scree...

I think this is where I need to look? ( https://psx-spx.consoledev.net/pinouts/#pinouts-spu-pinouts ) Sorts of, that's some older/inofficial hack. The official doc is here http://problemkaputt.de/psx-spx.htm Either way, if you search for something like IC310, the doc should contain part numbers of ...

When you are saying streamed audio, do you mean compressed XA-ADPCM (as used for audio in most cut-scene movies)? Apart from the decompression, there isn't much of a difference between streaming XA-ADPCM and CA-DA from music CDs. So it's very weird that one works, and the other doesn't. The other th...

Okay, fine.

The existing pal/ntsc mods are mostly intended to run import games, not to convert the whole console from pal to ntsc. The latter would only make sense if you really like the challenge of doing overcomplicated or outright crazy things. But if you are up for that... For 60hz boot menu, replace the bo...

Do you mean NTSC frame rate (60Hz), or NTSC color encoding (but what for)?

Anyways, to "stay" in NTSC, you may need to use a cdrom with an NTSC game on it.

Cutting the image into smaller parts to match the texture page limits sounds just right.

I've managed to copy the gamejolt page link, https://gamejolt.com/games/FNAF-ps1/832993 and the download for the recent version should be at https://gamejolt.com/get/build?game=832 ... ld=1520775

Ah, I've got it: On the github readme page you have a link to the gamejolt page, which has a link to the binary .zip file. I'll try to copy/paste the links from my tablet to my PC later, and then try if I can download the file on the PC. In the previous post, I made a mistake (now corrected): The fi...
