Re: [WTB] PlayStation development / service discs
Why? They've all been dumped and available for free. Plus, the ones that people usually sell are extremely old and outdated with the older Psy-Q libraries on them since Sony started distributing updates via FTP and private message boards. This is for redump.org (not all are dumped) and for some pri...

Re: PSNee further development
Hello, I would like to know if the APPLY_PSONE_PAL_BIOS_PATCH define of the PsNee source code would work to patch the bios of a scph-7000 version. Apparently the regional check that were introduced in the PAL psones came from the japanese versions isn't it ? I know that you can get around the regio...

Re: PSNee further development
The problem might be from Arduino, so don't worry too much. I get errors regarding the usage of pins in that function, which means the compiler is looking at it when it should not. Surrounding NTSC_fix() with "#ifdef APPLY_PSONE_PAL_BIOS_PATCH" fixes the issue. Applying this fix produced ...

Re: PSNee further development
superg: Do you have an updated code base for your version? Using your current git master branch just complains about errors in NTSC_fix(), even though I disabled the function per #define. Just in case you don't have time, I can take over from here, but I'll have to make assumptions :p Interesting, ...

Re: PSNee further development
I've been trying for two weeks now without success, as soon as I ask it here I find out how to program them. What I did is connect the ground on the UNO to the Reset on the UNO. as soon as they say there uploading I have to hit the reset on the Pro mini. That is overkill, ArduinoISP sketch sets the...

Re: PSNee further development
Hello I have a problem programming the Pro mini, for some reason with Arduino IDE it fails to program the chip. Does any one have a similar problem, I can program the Arduino Nano without a problem. I modded my PSX and PS one with it and it works perfectly. I also had a problem with my both Pro Min...

Re: PSNee further development
Have no idea, i cant read Fuses by Arduino IDE. MB i see problem, I must flash PSNee to Arduino by other Arduino and using SPI? EDIT: Nope thath doesnt help.. allday trying and no succes :( Basically you should disable bootloader and use 8/16MHz clock (maybe BOD bits but it works without it). Ardui...

Re: PSNee further development
hello,can I use teensy++ 2.0 for that project? I have also a Arduino uno to program the teensy without the bootloader I guess,if I cannot flash the teensy directly,thank you edit1: is this pins ok for the teensy++ 2.0? thank you #if defined(APPLY_PSONE_PAL_BIOS_PATCH) #define BIOS_A18 4 // connect ...

Re: PSNee further development
I think my wires were to long. Since I disassembled and reassembled the PS so many times I decided to take my kynar wires outside the console for debugging .. but apparently that doesn't work .. I guess that caused jumping voltages @rama3 That's what I do and I haven't encountered a problem yet. I ...

Re: PSNee further development
Hello everyone! A newb here! Glad I found you guys. Here's my story: a few years ago I bought an old PsOne Slim NTSC SCHP-101, PM-41(2) modded with an old 12c508P chip. Two days ago I decided to play Dino Crisis in that console, but for my surprise I had an error ("software terminated") S...

Re: PSNee further development
Those are very good findings guys! Would be perfect if we can get speed changes directly from WFCK bus without connecting anything else, we're don't have more gpio's on attinyX5, nice observation daywalker! Didn't have much time to look into it, busy with other stuff.

Re: PSNee further development
I'm undecided what would be best here, but some thoughts: - automatic BIOS patching: If it's going to be automatic, then we have to know the logic level for the involved pins. They will have to be connected either to A18 / D2, or to Gnd / Vcc. Once this is known, we can look at D2 or A18 for level ...

Re: PSNee further development
A few things, I got pro micro here and while ISP programming pin numbers are different, all the PSX pins that we use in psnee are the same, chances are that it will work as is. I am able to compile everything just fine with ARDUINO_BOARD defined but I can't flash it within Arduino IDE because they h...

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
Ok, the problem resolved. Turned out delayMicroseconds() yields different results for different chips. According to my logic analyzer dumps, there is a constant difference ~1.3us for every delayMicroseconds() call. Apart from the difference, the actual delay is quite different in the dumps comparing...

Re: PSNee further development
The 2uS delay: I never checked whether bitSet() and co. (Arduino convenience functions) compile to the same code on all AVRs. If they're not directly usable for port manipulation, that could explain the delay. I don't think the issue is with the oscillator, as we've just waited for the A18 signal a...

Re: PSNee further development
Ok, I almost burned my PAL PSOne by inserting my psnee modchip header to ISP by mistake. Got some smoke and had to bridge the fuse temporarily to get it working. I'm so happy it hasn't died as it would take a while to get replacement PAL PSOne shipped to the US. But on a bright note I figured out th...
