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

Hello, Im sorry for asking but i trying install Arduino Nano V3 clone with 168p chip. PS is 90002 with PU23. And my injection will end like this.

MCU frequency: 16000000 Hz
Waiting for SQCK..
highs: 2360 lows: 2364
pu22mode: 1

Then nothing. Where can be problem?

You have to try if that works, I don't think anybody used teensy board for psnee. As long as the controller ports allow for such an I/O configuration and fuse bits are correct it might work. I don't remember what specs Teensy has, last time I tried it it was for PS3 jailbreak a decade ago, make sure you're able to get 8MHz clock as otherwise timing might be a bit off. Good luck with that.

What are your fuse settings?

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). Arduino is not user friendly when it comes to fuse settings, I had to change Arduino configuration files by hand.

So it doesn't reach the code which is reading SubQ packets, double check SQCK and SUBQ connection, make sure you defined proper I/O ports.
When SubQ reading is fine, your debug will get dumps, this is an indication that modchip is analyzing the packets.

Thank for answers. Bud it seems like my problem is in burned cds... I just get one original cd and even swap trick dont work :( Im using CD-R and bur it with Alkohol 120% using Playstation settings. Sony CD-R.. :D OMG

Edit: I give more power to laser and its working now. I get somewhere, im reading data from cd, i can see data string but i cant see injection.

Edit2: Solved, burned on older PC with speed 10x (lowest posible) and its reading! Thx, for this mod chip.

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 Mini's from Microcenter. The solution was to reduce serial speed, it's somewhere in Arduino hardware configuration file.

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.

Than it program's I modded one of the PSX's (this was is a PU-20) I have with the chip and it works great.

Any way thanks for the quick replay I will try this next time.

That is overkill, ArduinoISP sketch sets the reset automatically, all you need to do is to connect UNO pin 10 to reset pin of the target (your Pro Mini), in case you haven't see this: https://www.arduino.cc/en/Tutorial/ArduinoISP

I know it's a overkill but for some reason this is the only way it will program without any problem.
If I connect it like you say I get only error's

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, the latest stuff is uploaded: https://github.com/superg/PsNee
What kind of errors do you get?
It's compiling on my machine but the code is kind of work in progress as I wanted to implement fuse checks and flexible configuration settings (universal region firmware or customized settings for specific PSX model).

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 a working binary that I could use on one of your PCBs.
The board works nicely in a 7502 console :)

Hi guys! :)

PSNee V7 turned out great firmware, but still not ideal ;)

I described a little, my vision of the new version - PSNee V8
PSNeeV8_concept.jpg
• Automatic selection of the region at the first start. (At the first launch, the chip determines after which sequence the SCEx console loads the disk, then the region code is stored in the EEPROM and read at subsequent starts. With three unsuccessful starts, the multi region is turned on).

• Automatic detection of the need to use NTSC BIOS Patch. (By impulse on A18. If not for t = ?, then no patching is required. Store the value in the EEPROM?).

• Refusal from Arduino.h (Refusal to use resource-intensive Arduino functions (digitalwrite, pinmode, e.t.c.). C ++ only.

• Optimization of the code for the possibility of working with low-frequency crystal oscillator 4.43 and 3.58 (for using the chip in the ColorFix mode).

• #define for automatic (default) or manual settings (region, NTSC BIOS patch).


Write what you think about it. What else should be added?
We can unite our efforts if you have time and desire to do it.

P.S. Sorry for my bad english :?

Thanks for the update, I have a question tho,
I have a pal pu-18. Dan the chip is working fine.

I just get a black and white picture on ntsc games.
After doing the googlie I found a mod, lifting pin 157 of the you and
Soldering a wire of the via to ground.

I did this but still have the same black and white screen.
Does anyone have an idea how to fix this without the need for another scart cable ?

Some ideas are good, just need to implement them :p
- The oscillator mod won't fit onto ATtiny: No pins left.
- Automatic region detect sounds doable. Not sure how reliable it'll be in practice, but doable.
- Removing Arduino functions: Why? They're nice and useful. Using Arduino is, imho, positive for the project.

You need a color mod to get color for your early PSX board. If you use a 700x series or later PSX, you won't need one.
