Re: PadTest

Great work, Shendo. I have been long missing mouse support for PSXSDK, and I would like to merge it into my fork. Is there source code available under a free software license?

Re: joymon - R/W/X-capable monitor over the controller port

Awesome job, socram! There is definitely some interesting, unexploited potential to the controller ports.

Re: How do I join the PSXDEV IRC Channel to chat with members?

I don't see why you would want to use IRC in 2022. IRC is still popular in free software and hacking communities. Popular free software projects such as Linux, ffmpeg or git are hosted on Libera Chat, which is an IRC network that was created on 2021. Nowadays we have Discord which is a modern day r...

Re: Cd functions when using exe

I'd recommend using some malloc routines when using the CD so you can load data into the heap, use it as needed and then free that heap space for other stuff later. If using fread(3) to read CD-ROM data, a more space-efficient (although possibly a bit slower) alternative is buffered I/O. This means...

How to get started with PSX game development

I would like to add some technical insights, in the context of PS1 development: Choice of programming languages - The original PlayStation CPU is based on MIPS I, so a compatible toolchain is required. gcc supports it with the `mipsel-unknown-elf` target. There are some instructions on how to set up...

Re: Is it worth it to make programs in full assembly ?

I feel it is kind of subjective. While it is true hand-written MIPS assembly might lead to more optimized code (size and/or memory-wise) compared to a C compiler in specific situations, IMHO usually it is not worth the extra effort nowadays, or at least for application-level code. Modern optimizing ...

It looks amazing! I agree with Shadow's suggestions: just make it run faster and smoother and the game is good to go. :D

Re: [Game] PSXPONG - A small pong to test PSY-Q stuff

Very nice for a first effort! Possibly a few monochrome rectangles (instead of variable-sized, texture-blending sprites) could had already done the job given the simplicity of this project, but it's definitely a good start.

Eagerly waiting to see new projects from you! :D

Re: PSX Physics

IMHO it depends entirely on how complex the physics are and a lot of other factors e.g.: game logic, code optimization, GPU performance, etc. When we wrote Deathball , we implemented circle-to-circle collision, circle-to-polygon collision, gravity and bouncing using fixed-point arithmetic and the ga...

Re: GDB server for PCSXR

First, the gdbstub revision pinned for the submodule no longer exists--it looks like it was removed with a force push or something. I updated it to the latest `master` and now the project checks out and builds OK. More like I forgot to push the commits stored in my computer. :lol: I have just pushe...

Hi and welcome, iNFeCTioN!

Apart from Psy-Q, there are modern alternatives to it that might be worth considering: http://www.psxdev.net/forum/viewtopic.php?f=24&t=3702

I'm glad you finally found the issue. But, after two years, new and better SDKs have been created. You should probably use one of them instead of Blade Libs. I have listed them on this thread.

Re: Is there a way to make PS1 game today?

You have several options: Psy-Q: proprietary, uses outdated versions of the GNU toolchain, lacking C++ support? PSn00bSDK : free software (MPL-licensed), aims for backwards compatibility with Psy-Q. Most feature-complete and actively maintained by LameGuy64. PSXSDK : free software (public domain), n...
