For now I'm more in a "learning" stage, and I don't take PS1 dev really seriously.
Also, Orion's SDK (I would say shortcuts) are Psy-Q compatible, since I did it with Psy-Q I guess.

Solved by using real hardware lol

Interesting ! Well, I think, for ps1 only, that it can be worth it to try making a simple program in full MIPS assembly, something that already exists. Of course, since we can handle C on PS1, why ignore it ? That is way easier than assembly. It's just that I thought about snes/genesis games made in...

Sorry if the question is already asked, but I want to know if it is worth it (or have some kind of benefits) to make programs and games 100% in MIPS assembly, and how to do it.

Thanks for taking the time of reading a stupid question lol

Thanks !
I used sprites to practice how to use them, so might be overkill but make me learn the good stuff.
For now I don't have much time to work on ps1 dev, but I'll post anything new

Hello right there ! It's been a crazy long time since I came here. I started PSX developement a while, and I have finally been able to burn on a disc source code and the game ! I'm working on this kind of desktop : - Windows 98SE - AMD CPU 1GHz (don't know the cpu lol) - 1GB of RAM - the PSY-Q SDK -...

I finally received my db25 cable, and decided to test like catflap reset the ps1 but I got this error. Any help ?

EDIT : "solved" that by using psexe.com and it works fine now.

Yes that's the 7. I didn't make the MM3, I bought it from ebay, so maybe there's different things. The most important thing is that it's working now.

So I tested the mod with a screen to see if the game boots, and yes, it does. And when the CD is accessed, the LED changes color. So absolutely working.

Solved. Soldered the last wire on pin 7, and the LED work. I don't have a screen available for know for being SURE that it works, but the cd spins, and seems to play.

My led has the "+" on the middle leg. The other 2 are probably "-". This is a red/blue led. I tried your thing and it didn't work. The red is wired at the place of the power LED.

What can I do now ?

No, for the cd unit it is ok, I just didn't push the lid button, I'm a fagot I know.

And for the voltage drop, I don't have ANYTHING about the led, that's an led that I salvaged from an old pc mouse. How can I "sink" the current ?

I solved my problem lol.

Ok thanks but know I have problems with the cd unit. No power comes from it and the motor doesn't spin at all.

Hello again there. So I just opened my ps1 scph-1002 for the led, and when I get it back together, the CD unit doesn't work AT ALL ! IT WORKED 10 MINUTES AGO! I have video and audio. Just the CD unit. It is the PsOne's, because you know, fmv skipping. SEND HELP PLZ ! Thanks EDIT : tested with anothe...

Oh sorry, it is not an rgb led, it is bicolor (RED/BLUE for me it seems). Something like this https://www.iascaled.com/blog/driving-3-pin-bicolor-leds-with-mrservo/ For the video it is this at 19:25 https://www.youtube.com/watch?v=hT5NSWS-znc If I solder the last pin of the LED on pin 2 of MM3, will...

I don't think you need any resistor for that, just put the 3rd LED leg and it's done, I've seen a video doing it, but not on my model.

Hello there, My PS1 is a SCPH-1002 PU-8 board chipped. I modded the LED with an RGB one, with 3 legs on it. For now, it is only red color since the last leg is not connected to anything. I want to know where I can solder the third led to have a CD activity thing. Like when the disc is accessed, the ...

Yes, all the drivers have been installed. But still fatal error...
