Re: Hack PSX-USB dual adapter due to max current limitations

Don't forget that connector has two vcc pins, a 3.3 V one and 7.6 one.
That's probably why your controller works but it has no rumble.

Re: Arduino Memory Card reader

Adapted? No. Because this simulates a PS1 side of thing and acts as a SPI host. However if written from the scratch it should be doable. The first problem with this I see is that you need a device that acts both as a SPI slave (for Memory Card) and SPI master (for SD card). So, maybe some other micr...

Re: PS1 Sound Trouble

You will have to open it up and see how it looks on the inside. There could be corrosion. For many people nowadays PS1 just takes space so they toss it in some storage (attic, basement, shed, etc) and there could be moisture. I bought one which was so bad that nothing (except plastic case) could be ...

Re: Return to the PSXSERIAL loader without resetting the PSX

You probably need a slightly different syntax.
The code i posted above compiles fine with the MIPS configured GCC core toolchain I'm using (PSXSDK).

Try with this:

Code: Select all

.global WarmBoot

WarmBoot:
   li t9, 0xa0
   nop
   j 0xa0

Re: MultiMode3 Source

Are you talking about PSone when you say PS1? Because PS1 means all PlayStation 1 models (fat and slim). Yes, MM3 works on PSone but if you are using it with a PAL console you won't be able to boot NTSC titles without a boot disc. That's because an extra check in BIOS was added to those models. To b...

I agree, it's very cool. Tested on SCPH9002 and SCPH102 and works great.
Maybe you should add a widescreen toggle option :P

Re: PS1CardLink - help with cable needed

Do you have a multimeter? Check continuity from adapter to the end of the serial cable. Also make sure that you actually connect to TX and RX lines on a cable. And leave CTS - DTR connected at all times. BTW: BIOS and games won't print debug info even if your cable is working properly because serial...

Re: PS1CardLink - help with cable needed

Connect CTS and DTR together on your adapter. If it still doesn't work disconnect TX(D) and RX(D) from cable and connect them together. Then use Putty to see if your adapter actually works. If it works then wire RX and TX back to your serial PS1 cable. If not get another adapter, ideally without exp...

As I said, try with Putty first to see if your adapter is actually working properly. Wire TX and RX together.

Re: JavaPSXSend - PSX Serial V1.3 Compatible

This is somewhat unrelated but CH340 and CH341 USB TTL adapters are easy to set up in Windows but for OS X i spent a decent amount of time hunting for drivers. I always ended up with a PL232 drivers which weren't working for this particular adapter even though PID and VID matched or at least the man...

Re: PS1CardLink - help with cable needed

Some new motherboards can come with a COM port, but only with a header and not a DB-9 connector. But anyway, short TX and RX on your adapter and see if you get echo from Putty. Then burn PSY-Q echo sample for PS1 and try then if you have an echo. If not then check your wiring, TX, RX and GND lines a...

Re: My new SCPH1002 console from eBay, Questions and options

Either your cable is faulty or TV doesn't detect that you have a RGB signal (due to low voltage on mode selector pin maybe). If you have a multimeter check Pin 16 on SCART connector and see if you get anything. Check Pin 8 also. Proper RGB cable will always show color on PAL and NTSC games on every ...

Re: My new SCPH1002 console from eBay, Questions and options

Are you sure you used a true RGB SCART cable and not just a Composite or S-Video through a SCART connector? Was it Sony's 1st party RGB cable or some other? Because colorburst signal and it's frequency (for which you would need to install crystal) is irrelevant if RGB is used. Maybe you can check on...

Re: JavaPSXSend - PSX Serial V1.3 Compatible

Thanks for this. Works fine on OS X 10.9.
Although it sometimes complains about a timeout but relaunching solves that issue.

If you are open for suggestions, add a progress bar/percentage info so the user knows how much more to wait.

Oh man that's a really, really bad modchip install. I would at least fix that horrible solder job if I got it like that. You can still buy chips or even program one yourself, files are freely available. The one you have is a 4-wire OldCrow. For your model you should get Mayumi. As for color, use RGB...

Re: PS1CardLink - help with cable needed

COM1 is probably the real serial port on your PC.
Go to Options->Preferences in MemcardRex and select a different port.

If you can't find any make sure you have drivers installed.
