My experiences are completely different: The surface of the lens needs to be cleaned once every 3-5 years, and that's all. Use a cotton swab with alcohol, or some spit on your fingertip. I have never had any problems with moving parts or lubrication. My consoles are SCPH-7502 and newer PSones, used ...

Suggesting to use 9-letter filenames on a console with 8-letter filenames seems to be a bit misguided. And I don't understand how (and why) you want to invent a numbering scheme where people might happen to use 00099 for the different titles. A descriptive name like SONICTSC.EXE might be a better wa...

I have redownloaded the original 7z file, it's now working and 50MB tall instead 30MB, apparently my browser screwed up in the first attempt. Decompressed it's 400MB tall, that's, well, outstanding even among other homebrews with poor value for memory ratio. It would be more impressive if you could ...

That looks nice. I've only watched the movie because I haven't been able to decompress the .7z file, the downloaded file is 30,246,760 bytes tall, but 7zip tells me that it can't open it as an archive (my 7zip version is quite old, but I never had that problem before). For lighting: I can't see any ...

That's supposed to look like that. To avoid that effect, you must re-draw the background in each frame.

Modchips are bypassing the SCEX check, I have never heard about a modchip that could bypass the TMD check, are you sure that your modchip can do such things? Even then, the boot rom is loading a plain TMD without texture, and there is no way to add textures to that. What you are trying to do isn't p...

The PS logo on the cdrom? That is displayed as raw TMD without any TIM bitmaps.
And the console will treat the disc as unlicensed and won't boot the game if you edit a single byte in that TMD file (unless you want to make or buy an expansion rom cartridge to bypass that license check).

Who or what is supposed to display TMD files when launching what? TMD files contain models. TIM files contain bitmaps. If you want to use a TMD to display a bitmap, then the TMD model would need to contain a single rectangle/polygon, with the corresponding bitmap being stored in a separate TIM file....

.BIN is short for disc image in CUE/BIN format .MDC is short for MDEC aka just another name for .STR files The game is from Electronic Arts, whom are known to come up with unusual STR file variants: http://problemkaputt.de/psxspx-cdrom-file-video-streaming-chunk-based-formats.htm I wasn't aware of t...

This the wrong thread, for no$psx v2.1. I guess that's because the v2.1 thread is sticky and appears above v2.2. I just tried 2.2 from the .de site, in winXP it crashes when launching via cmdline with a psx.exe as first param. dragging and dropping seems to crash the same way. Thanks! I'll fix that....

Yes, I could implement something similar as "N$gba --> Utility --> Cheats". In no$gba, the cheat codes are stored in the NO$GBA.CHT file, in txt format, as so: ;no$gba cheat codes library ; :cart_header_title:[NTR-]cart_header_gamecode:codebreaker_checksum ; [type [RAW] code [,code [,code]...

is there a way to save the whole cdrom tree view content in Filesystem viewer as .TXT? Just for bug reporting purposes? So we can send you the undocumented unknown formats inside the cdrom? I could add that feature. But wouldn't it be easier to just say "file XXX.YYY in folder ABCD" is ha...

Fuses? Pinouts should be as so https://problemkaputt.de/psxspx-pinouts-spu-pinouts.htm check for yourself if the 3.5V and 5V supplies are there. But be careful that you won't shortcut the supply pins while powered on.

No, that won't work. Xplorer and GameShark (Datel) have completely different I/O maps. And GameSharkProv3 sounds as if it's same as PAR3 (?), there isn't much known about PAR3, but it has yet different I/O map than normal Datel hardware. http://problemkaputt.de/psxspx-cheat-devices.htm If you want t...

Added two more chips to the list of still undumped firmware versions:
"424694 185" spotted on this DTL-H1202 photo: https://i.imgur.io/izRBiEN.jpg
"SC430952PC, G65C? 265?" spotted on this SCPH-103 photo:

What you have dumped/uploaded there is the regular v4.5a version with CRC32=171BDCEC. Why did you call it "SCPH-103(J)", is there a (J) on the sticker? It sounds like Japanese version, which it isn't. When dumping something: Please also include the part numbers for adding them in the above...

Thanks for the images. I don't know how to browse high resolution images on imgur, but these links with manually edited maxwidth settings seem to work... https://i.imgur.io/mFRcgMZ_d.webp?maxwidth=3000 front, with 40pin kernel "Sony, M534032C-05, 6112307-A" https://i.imgur.io/izRBiEN_d.web...

No, Shadow didn't say that disc "read-ahead" is similar to "a virtual memory access chip system". Your colleagues were perhaps too polite to tell you when you made such far-fetched comparisions. About your original question: The PSX hardware doesn't support virtual memory, so it ...

This bug in the collision of the spikes near the wall also has in the original game, it happens when a collision in the air near a solid object and the scenery wall is checked. Two ideas, either one might work: In the game map: Insert an (invisible) floor tile between the object and wall. In the ga...

PS. Easier way to figure out what RW and RW_RAW are: Can you dump a CDROM or Audio disc with CDRDAO in TOC/BIN format, with subchannel data? And post a hexdump of the first sector's subchannel data (it should occur at BIN file offset 930h..98Fh). And also include the TOC file (to see if it's using R...
