Re: is there another way to play FMV videos besides .str?

They are probably set to 320x240 at 15 FPS to save room on the disc, or the developers got lazy and just used what they had and what worked. I've got STR to playback at 30 FPS without any issues. It works fine if you convert everything properly.

Re: Laser/CD Unit Service

Use lithium grease on the plastic gears. Not oil. You only use oil inside the spindle motor.

Re: Laser/CD Unit Service

The sled (on both sides) should have grease, and all the plastic gears should have a little grease on them too.

Re: is there another way to play FMV videos besides .str?

Some developers wrote their own formats where they would store image data in a different way to either compress or lose artefacts due to a different encoding method. 8-bit TIM's would get you a framerate faster than 15 FPS (in theory). I would imagine >30 FPS for 8-bit if done correctly using a mult...

Re: tonyhax - PS1 softmod backup loader thing using THPS2/3

Depends on the programmer if they decided to add a checksum routine for the Memory Card data. As far as I know, it was not required to pass Sony's qualification.

Re: is there another way to play FMV videos besides .str?

I've tried that before, and it doesn't render 16-bit TIM's quick enough unless you reduce the image dimensions. However, if you make for example a quadruple buffer and write the 16-bit TIM's in a FIFO routine from the CD-ROM to RAM and then to the framebuffer, it might actually work and playback at ...

Re: tonyhax - PS1 softmod backup loader thing using THPS2/3

As far as I know, Sony left those unlock strings in by accident and they weren't use by developers. Developers instead had to buy debugging stations which had a different mask ROM in the HC05. Wow, you got quite a few games to overflow and boot from. "Tonyhax" isn't a good name for this exploit anym...

Re: tonyhax - PS1 softmod backup loader thing using THPS2/3

I’m especially impressed by the fact that your boot disc also unlocks the PS1 CD drive, as I didn’t even know that this was possible (AFAIK, all of the old Action Replay / boot disc methods required the lid button to remain closed). I assume that this will enable multi-disc games to work, and will ...

Re: tonyhax - PS1 softmod backup loader thing using THPS2/3

I can make a small program which will write the save game data to a Memory Card. I'll try and do it when I have some spare time. I'll have it read the save from the disc as a separate file and not from within the PS-EXE as a machine code so updates can be overwritten by using a program such as CDMag...

Re: tonyhax - PS1 softmod backup loader thing using THPS2/3

Nicely little exploit! Unfortunately it won't run all games though. You will run into some problems when you re-setup the kernel as some are very picky about how it's configured. In theory, there should be heaps of other games which can run the exploit too (not just Tony Hawk 2 and 3) which widens t...

Re: Laser/CD Unit Service

I believe Tamiya (the Japanese RC car company) makes molybdenum grease which isn't in an aerosol can. That's perfect to use on the gears and rails.

Re: Want to flash corruped BIOS

How did your BIOS become corrupted? It's mask ROM. It shouldn't ever become corrupted. With that said, you can't flash it. You need to replace it or solder up a new chip with the same addressing, data bits, voltage and size (512 KB).

Re: [WTB] Screws!

I have HEAPS of PlayStation 1 screws if you need some. Let me know. I have both the black ones for the ABS shell and the bronze/gold ones for the PCB inside the console. I also have some PU-7/PU-8 ground tabs and a spring for the door/lid for use with a Game Shark (etc). http://www.psxdev.net/forum/...

Re: SCPH-1000 - Sound issue

I believe the controller inputs stall (due to poor programming in this version of the BIOS) if it can't detect a drive (in this case, the photo diode can't be detected so it thinks there is no drive). I replied to your other thread, but replace the motor controller and optical block with a different...
