Re: PSIO alternative ?

Arduino isnt powerfull enough, RaspberryPi probably neither. especialy the IO output. Maybe if you take the ALTERA Cyclone 3 FPGA and add it to your RaspberryPi you might be able to put out the right IO with speed and accuracy. but basicly youll be reworking the PSIO and the price ;) Raspberry can d...

Re: PS1 Memory Card does not format or detect (Genuine)

You could desolder the actualy flashchip if all else fails and use a eeprom reading to look at the bytes, recover whats lost. but thats only usefull for if you want to recover something, if memcardduino doesnt see it, or fails like your ps2, sounds like either the controll or flashchip is broken.

Tried other things, dint work. Thanks Gwald for your Makefile modifications, they are nice, and I was thinking about making a script that would do the configuration and making automaticly, but thats probably best for when I actualy get a working PS-EXE. http://www.psxdev.net/forum/viewtopic.php?f=67...

@Gwald, how big is your linux ecoff file after running the convert(elf2ecoff) tool and how big is the Executable when it is "converted" into a PS-EXE? I seem to run into the same old problem again I had earlier, it goes from arround 1.1Mb, 730Kb (stripped) eld to 716Kb as a ecoff, then the Eco2EXE m...

Re: SOS how to make a serial cosomolink usb

The PSone serial internal is 3.3v I believe. The whole MAX232 or other voltage convertion method is done purely on the assumption your going to connect to a true RS232 computer connector. If you going to use a PC or laptop that doesnt come with a serial port then you may just buy a USB serial conver...

Re: problem converting .rom to .exe

ROMprod is if I understand it correctly, made to convert a PS-EXE to a rom file for your Gamehunter. So you can run a EXE from the card instead from CD or serial ca...
