Re: ESP8266 Wifi Experiments

Quick update. Everything is working very well with the PSXserial client. 100% success on EXE execution, and the reset functionality works perfectly and is very useful. Just console mode to finish and thats it. Currently on with :- Flashrom on PSone - so the PSXserial can load instantly from ROM usin...

Re: Doubts about PSX Serial Cable

For PSXserial, you can use pretty much any USB UART. I have tried with various models. You need one that runs at 3.3v, either of those linked to will be fine. I personally use the CP2102/2103 versions which work perfectly. FT232 (usually fake FTDI chips - but work fine) CP2102/CP210x chips - work fi...

New Homebrew Game : Wartris

Tetris Clone, looks pretty cool. Wartris is a Tetris variant and homebrew game for PS1. Developed in 1999 by Pissteam a former group of the Playstation One demoscene. Although Wartris can be played in single-player mode, the focus is on two-player battle mode. The object of the game is to force the ...

Looking at the pinouts :- IC102 - Boot ROM Pinout.png I assume (sorry for all the questions) EEPROM /CE goes to Pin98 of the CPU /OE goes to /OE on the BIOS ROM Pull /WE high to +3.3 to...

Re: ESP8266 Wifi Experiments

Hi Rama, Thanks for the interest - got the modchip working fine with 4 wires, didn't need the link wire (will post a pic next time I open the console up) ESPLink is only available for the ESP8266, and I think adding modchip functionailty to the ESP-Link sources is probably way beyond me, especially ...

Re: ESP8266 Wifi Experiments

Update Have fitted one of the ESP8266 modules to a PSone, works very well same as a regular PSX.. as expected. Simple, just connect RX, TX, GND and 3.3v and the PSone will power the ESP8266. Be careful, if you are using a USB version for reprogramming, you will need to put a diode between the PSone ...

Re: PSone Internal Cheat Cart / Flash ROM

That makes sense now. Assume the mapping of the switch into ROM is done by the GAL/PAL? I only have 256k flash parts on hand anyway so that shouldn't be a problem. I do remember you looking at the AR carts and USB transfer a while back..do you know how hard would it be to implement the contents/mapp...

Re: PSone Internal Modchip

Thanks Trimesh,

I shall give this a go. The seller of the PSone on eBay mentions running Caetla - by patched would I be able to just flash caetla?

Would I be correct in assuming that if I use a supported flash part, and wire up W/E I should be able to flash it using xflash?

Thanks

Re: ESP8266 Wifi Experiments

More speed improvements. Now transfer speed is the same as using a CP2103 USB UART, with 100% reliability. Have started on the console mode, that will be a command line option so whether or not it goes into console mode post-execution. Also, got sick of constantly reloading the PSXSerial CD, so swap...

Re: ESP8266 Wifi Experiments

Made some more adjustments to the transmit part of the code. Now the transfer speed is around 5x faster than in the video with the ESP8266->PSX connection still at 115,200bps. Also, need to code in the handshake... it works at the moment due to their being a 2 second delay after sending the sync byt...

Re: ESP8266 Wifi Experiments

And we have success! Fair bit to do, polishing up the client side, speed improvement and console mode. Then going to add serial support to the code so its a dual purpose tool, as I think the only other linux client for Psxserial is the java based one. The Python code is horrible, with no checking of...

Re: ESP8266 Wifi Experiments

Further to the above. Went trying to log serial activity to work out the protocol, and remembered that someone on here documented it.. of course, Shendo did this years ago... @rsoft: Yup. As I said I used SerialMon to capture data and analyzed it. The protocol is basically this: 1. Send sync byte (0...

Re: ESP8266 Wifi Experiments

Started work on the client.. promising start. Currenly written in Python3 so will run on Windows/Linux easily. Only using standard modules so setting up should be fairly trivial.

Re: Recompile Yaroze Source

Hi Chris,

Did you manage to test the output from your setup on real hardware at all? I have a nice linux machine setup for this and was going to give it a try.
