Re: sioloader

Just tested my PSone at 345600 using an ESP8266 as a uart/TCP bridge and worked fine too

So the issue lies elsewhere it seems?

Re: sioloader

Inversion step? If I understand you correctly, the only part of SIO that is inverted is the handshaking lines.. which arent in use for this application. If I am honest, I do not think the issue is with the USB UART but it is easy to exclude from the investigation. I have had issues with the counterf...

Re: sioloader

I need to do more testing at my end with other UARTs. I have also only tested the fast speeds for uploading to the PSX, not downloading from it. In both instances my test setup is using half a link cable.. so the connection between the FTDI and the PSX is around 80cm long. Also, Squaresoft74 has tes...

Re: Newer X-Flash Builds

My thoughts exactly which is why I went that way. I had a similar issue years ago on an STM32 I was targetting. 430600 definitely doesn't work on the Playstation reliably.

Re: sioloader

It's a PSX-EXE... So you would need to make an ISO of it.

If I find time I will try and build one and upload it at some points.

Re: Newer X-Flash Builds

I have put the changes I made to hitmen serial into a standalone EXE. The source is embarrassing but it does the job :-).

https://github.com/danhans42/sioload/

Selectable baud rate 115,200 or 345,600. Simple Python3 client included.

Source included.

Enjoy

sioloader

SIO Loader for Sony PlayStation Consoles Basically its the source of Serial v1.3 by Hitmen but with selectabe serial speed. Uses a very simple serial cable (rxd/txd/gnd) that is easy to build. The client is written in Python 3, and has been tested on Python 3.7 on both Windows and Linux. It requires...

Re: [DEV] - Flash Boot Rom PS1

Hi xrider.

Great work. Look forward to testing! If you can drop me a PM with the details and I can send you payment for the module, and see if we can get it flashed in the console using the software from obscuregamers in the link.

Re: Newer X-Flash Builds

Lol, I changed the baud rate.. that's it... Just changed the speed in the define for BPS in the hitmen source. It also ran at 230400, but wouldnt work at 200000.. I don't understand it, I tried myself in the past. I can only assume it's the simplicity of the graphics routine used or the fact that I'...

Re: Newer X-Flash Builds

Hi All, Bit of an update. I don't know if this feature will remain or not but have managed to shoehorn PSX-EXE loading from SIO into xflash. I had to move the internal data buffer for loading ROMS to a higher memory location to get it working, and it currently only seems to work with EXE's at around...

Re: [DEV] - Flash Boot Rom PS1

Hi, The ST29EE and ST39 series are programmed differently. The 29 series is written as words (128/256byte)whereas the 39series series is written as a single byte so the flash algo will be slightly different. The write commands are pretty much JEDEC standard, its just the order in which they work. If...

Re: [DEV] - Flash Boot Rom PS1

The code to write to flash is fairly easy, you are just putting the commands to the correct addresses. You may be able to write to it by pulling WE low when flashing and wire everything else exactly the same, omitting the A19 pin. The BIOS sits at 0xbfc00000 to 0xbfffffff so we could look at writing...

Re: [VDS] "pseudo Net Yaroze": chipped console has integrated STU

I do not feel you are being abusive. I agree with your point. I wouldn't sell something similar for less because of the time it takes to modify the console and also produce the CD's. This is why I don't modify consoles for selling on as it doesn't pay for my time financially. People generally do not...

Re: Newer X-Flash Builds

Hi Squaresoft,

Thanks for the testing on the test versions. I have that particular version of the regular xplorer and it does throw up those checks so will investigate those.

I have managed to source an old Toshiba Satellite machine so will be able to do tests with the parallel cable quite easily.

Re: ESP8266 Wifi Experiments

Little update on this. So I have now got a ESP32 WROVER module up and running with MicroPython. Works great and have moved over my psxserial client to it. At the moment the code mounts an SD card, and sends MAIN.EXE out of UART2 to that is mapped to pins 25/26. With this being the WROVER part, it ha...

If it's not supported it probably still isn't. Can you drop me a PM with the details of the EEPROM and will get the part onto my to-do list? If you can let me know the mode number of the EEPROM, and also what xflash detects (unknown followed by two hexadecimal number) If you are in a position to tes...

Re: Newer X-Flash Builds

Squaresoft74 has kindly done some testing for me, and the results are very promising.

Need to fix some minor issues and implement a few suggested options and will get a release out shortly.
