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 often use ...

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. There ...

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 the...

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. https://github.com/JonathanDotCel/helloworld_and_flappycredits if you want to use the official tools, you are stuck back in DOS/Windows Also, there is the psyqparser solution, ...

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=62&...

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 aroun...

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 hav...

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...

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 115,200b...

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.

Yeah definitely. Keep in touch.

After talking with Squaresoft74 over on the discord, I am currently adding PAR2 detection and dumping/flashing so it correctly changes bank.

Also, siocons sioload now runs at 1036800bps. Silly fast,

You need the missing tool to build a rootfs on a memory card. I suppose you could look through the code to see how it's mounted and try and to understand the format. I tried this years ago with a pre-built image, and that was always the stumbling block. It didn't output and video from memory, just s...

Necroposting to say that this won't work as-is on the PSOne. The BIOS prior to PSOne contains code that is responsible for executing the PIO port's ROM(the AR ROM). That's gone as of the PSOne. You'd need to replace the BIOS with flash and hack the PSOne ROM to add code for comparable entry points ...

Either! You just need a +3.3v UART. They both do the same thing..

I was too lazy to do the above so went old school and use the full 16bit compilers etc all in dosbox. It isnt pretty but works well and I have external scripts to open dosbox and compile and exit again. Nowhere near as elegant as running it natively on a modern machine, but I work on Linux so was th...
