It should work okay it's compatible.

WCH stuff is normally alright too, fairly reliable.

Look on here, lots of threads in the hardware section.

Essentially you need a link cable and a USB UART, chop the plug off one end, work out which colour wires are Rx/tx and gnd using a multimeter.

Then connext Rx to tx on the UART, tx to RX and gnd to gnd. That's it.

Depends on your definition of expensive, I think uneconomical would be more apt. You could go to a guy in the US that makes them and pay $80 or buy a link cable and make it yourself.

I used to sell them a while ago, someone contacted me recently and I am building them one.

If you are UK I may have a spare half link lead and could build you one although would need to check if I have the requisite parts. You are looking at around £21 delivered in the UK

You need a serial cable. The port on those carts is not parallel compatible.

i have another gold finger cart on the way, how would i dump the rom?


You need to make or buy a serial cable. You can use unirom or nxflash to dump the carts contents over the serial port.

Have a look on here for serial cables, lots of posts.

@Squaresoft74 2megabits is 256kilobytes. They ...

Hi,

Yeah the CAT EEPROM has a separate Vpp pin so can't be flashed.

On xtlash.. erm I really don't know. I no longer use PsyQ and given how good unirom is now it's almost redundant

If I can move it all over easily to GCC/Nicolas toolchain I may.. however that would then exclude CD support

Its been a while since ive posted here, so thought I would update on something I have been working on.

Nicolas over on the discord mentioned a device that he had looked at that, that could provide USB device/host functions and was bus compatible with the PlayStation.

The device is the CH-376 ...

If I am honest, I would just look at using UniROM to flash your cart. Its more recently updated and handles everything a lot better.

Its not just a matter of burning a ROM to a CD, it needs to be packaged into a romfile for xflash to read it, same with IniROM.. However, the unirom downloads have ...

If you are flashing anything other than an xplorer I would flash from CD, as you can't use the port on those for PC connection.

Alternatively, you might be able to send the ROM using an xplorer and then hot swap and flash it.

@Xrider - look at pickit2 plus . Think its supported in that

I use some open libraries that are called nugget, with that I can use an off the shelf gcc-mips and all that comes with it.

if you want to use the official tools, you are stuck back in DOS/Windows

Also, there is the psyqparser ...

Depends on the definition of SDK.

Pocketstation aside, there has been work on converting the PsyQ libs for use with a modern GCC, which would then allow the use of VScode, which is what I am using at the moment.

The original project was psyq2elf - here http://www.psxdev.net/forum/viewtopic.php?f ...

Thanks @trimesh.

I think I still have one left, they are roughly as pictured in the first post. I just go for cheap and functional hence the heatshrink approach.

Drop me a DM on here, or via my page (see link in my signature). Its more expensive than when I first started doing them. Looking at ...

You have a few options..

so if you are using caetla as trimesh suggested, you can use either catflap or the MSDOS Caetla tools to use console mode. You just do printfs etc and they are redirected to the PC without using SIO.

However, if you want to use the serial port (and have the hardware) you ...

SO, your assumptions about the eeprom are correct.

You can do away with the GAL, and just use a ROM. However, the GAL handles more than just PC communication, its an address decoder and also provides 2 1bit inputs.

The GAL allows the memory space to be divided up and provides the chip selects to ...

The notorious device bricking is down to counterfeit devices.. buy genuine its never ever an issue.

Glad to hear you have sucess with it, I don wonder how many people use it.

I still stand by FTDI, especially for Yaroze purposes, there isnt anything else available currently that offers the same handshaking flexibility, For non handshaking i find siliconlabs or the ch340 work perfectly fine. The CH340 is like around $2.

Espressif dont make anything USB currently, but yes ...

Yes works fine at 1,036,800bps with a 1.5metre link cable. USB cable length makes no difference whatsoever in my tests.

Most USB UART ve found will work absolutely fine up to 2,000,000bps. Using RS232 voltage levels you are kind of stuck at 345,000bps.

I made the decision to keep nxflash at 115 ...

Sorry typo - I meant sioload not siocons.

I actually need to check that haha. I left all the flashing upload/download functions at 115,200 in nxflash just to be safe.
