Re: SCPH-7502 = Better graphics ? ("PS1.2")

Just variances in hardware. A major one would be CD-ROM reading speeds, and a minor one would be that the PSone chips would be completing operations quicker. Same clock speeds of course, but at the silicone electron level they are probably completing operations a bit quicker so they flag an interrup...

Re: Green debug playing only audio cd

The board itself might need to be calibrated because the older PU-7/PU-8 boards didn't do automatic calibration. Only the later board revisions did that.

Re: Playstation 1 Exe - Windows RNC Packer

How does it pack the PS-EXE to gain additional room to add additional code for hooks, etc? It can't work with every game. I'm sure it causes some to crash.

Incredible how adding a simple op-amp circuit did increase color burst but didn't make image worse.
I'd presume that it could be to bright or to much of a contrast.
The operational amplifier circuit did not work. I didn't use it.

Re: New KSM-440BAM requires service?

Ah, depends when you bought it from but if that's the seller with the hard to find 'new old stock' then yes those should be brand new still.

Okay, you need to adjust the laser then. Do the eye pattern calibration routine with an analog scope.

Re: New KSM-440BAM requires service?

The sled tracks are worn. New lasers do not exist, they are refurbished units.
The laser requires an increase in laser power slightly for reading CD-R's.
Save yourself the hassle and get a PSIO Cartridge when they are back in stock.

Re: HELLO

Xor (aka Loser) should be still hiding on EFnet. He might be under the alias 'xorloser'. His site is still up. You can try sending an email to the postmaster there and see if he replies if you can't find him on EFnet. He quit the PSX scene 20 years ago.

Re: UniROM 8.0.5 released with fast SIO, SIO redirect, NPAL fixes, etc.

Burning at 1x or 24x doesn't make a difference. The ATIP contains the disc's min and max write speeds and no manufactures use 1x anymore because CD-ROM drives are so stable nowadays (and have been for over 2 decades). 1x was only used in the very early days of CD-R burning.

Re: Help to get started

Cool project, but yes it will be very slow. Also, the PSone has the serial pads on the mainboard still. You just need to solder directly to them.

Re: Desperation about Sounds/SPU

Yes you can do that with XA. Have one play the intro, and then another which has been composed to loop. Of course, there will be a delay when it loops because the laser head needs to move back to the start of the sector. VAG does not have any delays when looping because it's all RAM based.

Re: PC Mouse on PSX

You don't need to use the serial port if you make your own library for the MIPS side. Just translate the keyboard buttons to analog positions. The amount of bits you have is a 32-bit unsigned char (0x00 to 0xFF) on each axis which is heaps . You could have probably up to 10 keyboards connected to th...

Re: SPASM Assembler

Don't use SPASM. It's outdated and the opcodes it uses are different from the MIPS opcodes.
+1 for ARMIPS. It's also a good one to use.

Re: Connecting the PSX to a modern PC

No, Windows 98 is recommended for Psy-Q because it was designed for Windows 3.1 and Windows 95 with the MS-DOS kernel. Windows XP will probably work, but I don't recommend it because you will run into issues at some stage. You cannot connect an Action Replay without the CommsLink ISA card (you could...

Re: Connecting the PSX to a modern PC

The NT kernel based systems don't have direct hardware access to the ISA bus unlike DOS based systems. If you're really set on sticking with the horribly outdated PSDEBUG program, you'll have to use Windows 98 (preferably Second Edition) for that.

Re: Connecting the PSX to a modern PC

Use the NO$PSX emulator to debug. It's way more accurate then PSDEBUG. I think PSIO will have a debugger soon too so you can debug in real-time on the PSX.
