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...

Re: Newer X-Flash Builds

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.

Re: ESP8266 Wifi Experiments

I have had limited time and have been on holiday and wanted to get the serial routines added to nxflash, so no real progress to speak of. When receiving from the PSX, there are heavy packed losses. I am not sure if it is down to the esp-link firmware having barely any buffering in that direction, or...

Re: Newer X-Flash Builds

Quick update on this, as have been away for a bit with work and holiday. Anyway, I now have successfully added both upload rom to RAM function, as well as flashing from RAM. I need to adjust the menus and text to make the menus accessible as well as the text. No checksum stuff in there, but I have t...

Re: Homebrew AR/PSX blaster like project

Cool. First job for me is to get a DIP socket mounted and wired up and get the PSX working with it. I have 3.3v flash roms spare so that will eleviate the need for a voltage regulator on the cart. I also want to add a header to my board so I can easily breadboard extra hardware to it - and start loo...

Re: MIDI controll

Serial is fairly simple although I remember midi having a wierd baud rate the pax should be able to do it. I suppose the difficulty would come with the clock part of it so everything stays in sync.

Is there a way with PSYQ to create an expansion rom header? or must it be hacked in manually/with a custom tool?
Look at romprod by sicklebrick (on this forum), or Romboot here - https://www.sinistersoft.com/romboot or run rom by barog (although I think with latter you need a CD in the drive).

Re: Homebrew AR/PSX blaster like project

I have also started looking at this, so if you want to compare notes it could speed things up. My expansion breakout board is nowhere near as pretty as your custom one. My idea is to add a header to break out the connector as well as an EEPROM. I managed to remove the connector from an AR clone that...
