Try a PU-7 or PU-8 board with the analog servos and adjust the laser power slightly since CD-R's require more gain

Re: psxdev.net slow loading and timeouts
I couldn't find anything in the database. The issue might be on your end because multiple test sites worked fine with a paint time of approximately 1.5 seconds. Here is a result from Germany: https://www.webpagetest.org/result/230816_BiDc71_35W/

Re: Batch STR Converter
Why go to all that trouble when you can just use FFMPEG. Run the batch below and then merge the WAV and AVI in MC32.EXE to produce the STR.
Code: Select all
@ECHO OFF
CLS
ffmpeg -i input.mp4 -vcodec rawvideo -s 320x256 -r 25 -an output.avi
ECHO.

Re: Linker error: Symbol not defined
Don't include libmcrd.lib unless you need it as it'll just bloat your CPE/EXE. The same goes for any other libs if you're not using them. Not sure what's going on, but try replacing libsn.lib with the 4.6 version instead. It looks like mine is from Wednesday, 28 July 1999 compared to Friday, 18 Febr...

Re: TIM transparency
Colour multiply seems to have the most realistic effect, but don't use emulation when experimenting with 3D especially in the field of lighting. Always use real hardware for proper accurate results.

Re: [DOWNLOAD] PlayStation 1 BIOS Collection
I would like to do that, but I don't want to risk taking appart my PS1. The last one I took appart, the connector for the disc drive broke off the board. I've had that happen too. It's due to a lack of solder paste from the factory which Sony used to manufacture the PlayStation 1. All you gotta' do...

Re: Black & white image on SCPH-1002 and there is no pointer
The flux used by the factories Sony went with isn't water soluble. Alcohol will help dissolve it, but you'll need to use something like a toothbrush to help assist with breaking it down further into the solution.
There is no service manual for the PU-7 or PU-8.

Re: PS1 Menu+Trainer Tool v2.4
NO$PSX and DuckStation are far more close to real emulation than pSX Fin (this emulator has not been updated in many years). The closest however so far to real hardware would have to be Xebra.

Re: Black & white image on SCPH-1002 and there is no pointer
I'm certain they're just covered in old flux. It's difficult to tell without either cleaning them or testing them with a multimeter. As NO$CASH said, they're just inductors and they're cheap to replace anyway. Also check the RGB (colour) encoder chip which also looks like it's covered in the burnt f...

Re: Is it possible to debug PS1 code with an XPlorerFX ?
To debug, use NO$PSX with the Psy-Q symbols. However, for basic debugging just adding printf() will suffice.
