Re: PSNee further development

These mini Arduino boards have excellent power regulation for what little they consume. I don't think you have a power problem. You said "some games stops loading" and you use a PAL PM-41. I don't have the region patch stuff for these consoles yet, so it will only boot PAL licensed disks. I have no...

Re: PSNee further development

and you would start injection whenever you see any clock on WFCK or do we need another delay? For time-keeping, I would probably use a pin change interrupt and just read the timer value when the pin changes. If we only need to differentiate between two clock speeds where one is twice the frecuency o...

Re: PSNee further development

Hi, so since i already had recordings of my PU-22, i extracted the WFCK frequency and plotted it over time in the attached image(ignore the jitter). I never noticed before that it was changing because the first time it doubles it's speed from ~7.25kHz to ~14.5kHz, the injections are already over. wf...

Re: PSNee further development

You inject the license symbols 6 times. That could be too much for some anti mod games. It's possible that you're still in the sending loop while the game has long moved the laser, and thus it becomes detectable. Just my observation, I experience a delay in boot on my test PAL PSOne if I do inject_...

Re: PSNee further development

Hey superg, Sorry I did not mean to change the topic of this discussion, I just wanted to have a ready to go version of this project to fit on a tiny25. Basically to use it for myself and after I was done, wanted to share the code. I read the rest of this discussion and yes, i have a high voltage pr...

Re: PSNee further development

I'm having troubles enabling bios patching on ATtiny (84 for now). I think it's timing but can't figure out the correct values. I used my logic analyser to monitor A18 / D2 but I'm getting different values every time and it's not clearly visible what's going on without seeing the other address line...

Re: PSNee further development

I don't think that will work, as far as i know the fuse settings are packaged into the .elf file in Atmel Studio. Without having checked this, i seem to remember that the Arduino IDE flashes the .hex only.

Re: PSNee further development

I inject the code six times because you're doing it as well. I am just not injecting each of the three regions twice, but the correct region 6 times. But also i did not investigate that part yet since it worked. So you would reduce the number of injections of the correct region to two? This is the o...

Re: PSNee further development

Hi, first of all, this is a great project! I wanted to use this code to make a mod chip based on the AtTiny25. For that, i modified the code a little. Some parts, i think, are a bit simpler than in the original PSNee code. Others aren't ;) Also i wanted to use Atmel Studio to get rid of some overhea...
