Just curious about how a PS1 ISO / Bin/cue from the internet was able to play a compressed short movie...

Saw a copy floating around of some old movie that was burned to an iso or bin file that was able to run on an emulator to play a movie. I think it had a menu too like a dvd and I think chapters.

Now I'm wondering if there is a legit way to do this with available tools. I assume the video file must be converted to STR?

Gameshark codes work in Duckstation but not real PS1 Gameshark

Hi, I hope this is the right place to ask this sort of question

I understand that different implementations of GameShark on real hardware vary drastically, like depending on if it runs on catridge or on disc, stuff like that, but I want to know why exactly it is that I can't get gameshark codes written in DuckStation to work in any of my GameSharks at home; I have a GameShark cartridge, 3 GameShark Discs, and even a burnt disc of the krHACKen Cheat Engine Compo, but none of them seem to work for the code I have for a certain game

What is the best way to run GameShark codes on real hardware? Is there a certain cheat engine I should be using on the compilation disc, or a particular version GameShark cartridge I should acquire, or a ROM I could try writing to my GameShark cartridge? (It's a GameShark v2.1)

Any help would be appreciated

Autoplay?

Hi friends, I have a PSX that I use to play audio CDs. It works great.

My only qualm is having to press “Start” on the controller to play CDs.

Is there an autoplay setting / mod / etc, so that when I put a CD in and close the cover, it will just start playing?

I don’t need stop, fast forward or anything like that. Just “Play”.

Model is SCPH-5501. I don’t have it hooked up to a TV - the multi-AV cable thing just goes directly in my receiver.

(I’m not an audiophile, I was gifted the PSX by a neighbor when I needed a CD player)

I know the PS2 remote works on the PSX, but would rather just have autoplay if possible.

Making changes

Hey everyone I'm new here. I'm trying to make some minor changes to ff7, mainly the character pictures on the menu. I got to the point of inserting the png back into the game, but I get this instead, I've also resized the image. Any help would be great.

Does anyone know how to extract PS1 MIDIs and sound fonts? Im trying to get the files using VGMtrans, but for some of the MIDIs it only plays the intro, and the soundfont is just silent. Anyone have any experience that could help? Game is RE 1.5

Quick question about PicoMemCard

Hey, I'm building a PicoMemCard using the smaller RP2040-Zero, and I noticed these three components on the board. I can't seem to find any mention of them at all on dangiu's github. What are they for? Are they buttons? They look like buttons judging by the corner solder points, but there's no mention of them.

What do?

Thanks for your help.

I have no prior coding skills what should I do to get started

I'm obsessed with the ps1 i'd love to make a game one day. Definitely more interested in 3d games I know it could take years and I might not even be cut out for this but it's worth a try to ask and maybe have things click to get started. any info is appreciated mostly interested in what programs I need and what I should focus on. Maybe throw in some "if I would have known I would have tried to learn this first" lol thanks guys.

Help with PSn00bSDK

I’m pretty unfamiliar with what I am doing but I want to try developing a PS1 app. Everything I find online seems to be out of date or not very clear. Can someone walk me through step-by-step how to set up PSn00bSDK or point me in the right direction to find resources.

Adding PIO Port to PU-23

Since I couldn't find any real information aside from "Look at the schematics and figure it out," I compared the schematics for the 900x and the 700x and have identified the "CLXXX" test points for every PIO pin designated in the drawings for the 700x. There are PIO breakout boards online and brand new female connectors available. I would like to know if anyone has undertaken this procedure and has any extra info not necessarily related to soldering but to requirements for it to work, like wire gage, adding resistors or other components.

Mortal Kombat psx

Saw people have fan ported 90s pc games to ps1 before. Was wondering the possibilities of getting mk1 to run on ps1? Always bugged me that it's the only one that's missing.

DB25 connector on back of GameShark cartridge

Can I connect my cartridge to a PC with it? If so, what type of things can one do? Sure would be nice to put unirom on it.

'How to', just about everything?

Hey all, how are you? I am intrigued by homebrew on PS1, can you enlighten me please? I own a chipped PS1, how do I view homebrew content? I am not a developer or even much of a gamer, but would be amazed to see some contemporary creativity, especially graphical or musical demonstrations. Thank you for any input, even if it's onyerbike lol.
