Re: Gameshark inside

Action Replay V3 and V2 source. Not the full source though as it's missing some crucial stuff in regards to the low-level hooks and kernel handlers so it's pretty much useless. As for how the cheats work though, it might be useful :)

Re: Boot logo interruption?

Your disc image was missing the license information in the first 12 sectors (which also contains that PlayStation TMD logo). Yes, you can add this: VSync(170); // wait (lets the user hear the BIOS chime trail a little before stopping it) SsInit(); // initialise the sound system (SpuInit() is called ...

Re: PSX spu and FF7 music

They play them like like a tracker does on the Amiga for example. The PSX SPU has channels which can play high quality samples. Using clever code, you can swap them out quickly from working memory to SPU memory, thus giving you a dynamic range of music or audio effects. You can extract them using th...

Re: MIDI controll

You can use the serial port, but you'll need to make your own hardware and write some software to what you want your MIDI program to do.

Re: Abe's Exoddus (decompile)

That's pretty interesting! I wonder why it happens. Maybe the loop gets interrupted and it has a delay before re-processing it?

That is insane. Can't believe you've already got some of it decompiled and reversed back to C!

That document is over 15 years old. There's no point really in updating it because it just covers the essentials when getting started with the PlayStation.

Re: Video IDU test v1.1 disc

All it does is loop the DEMO 1 intro video over and over, and I noticed that there's a padding file in there which could be deleted which would decrease the filesize. For some reason there are also heaps of other blank STR files. Probably to edit it in the future to remaster it with more videos. The...

Re: Playstation maintenance/re-calibration to improve reading/audio issues?

Usually it's the motor alignment failing due to degraded plastics. Those potentiometers are used to adjust the voltage rails to the diode as well as adjusting the phase. Best to not touch them unless you have an oscilloscope to get the eye pattern present to calibrate. There's a topic about this in ...

Re: Compiling: beatmania APPEND 5thMIX -Time to get down-

That's strange. They've made their own printf function it seems and it's a multiple now of Psy-Q's. You could try disabling linking with the default Psy-Q libs and not include the one that has printf, or if that library source is compilable and linkable, rename the function.

Thank you, if you are not willing to sell one of the CD’s then I would really like a dump file please.

Re: Assemblergames.com going in 30 days

We'd just have to somehow backup the PSX development section. Most of the PlayStation guys from there however are now on this forum. We got Pool7, Trimesh and Jackhead so far. They were some of the top guys who were very useful to the scene with their knowledge as well as hardware and software shari...

Lift pin 157 on the GPU and tie the pad as seen in the 7502 photo high to Vcc (3.50V) instead of Gnd (0V).

Please don't advertise on the forums when it's got nothing to do with PlayStation development. That's the second time you did it. I've been monitoring your posts recently, and the stuff you've been posting isn't even really all that helpful. It's always just "your own two cents" on post after post. ...

Best to play around with the Psy-Q examples Sony originally provided.
