750x for 12F629 & 12F683

i you're use pics a lot buy the 12f683 they dont have OSCCAL values at all

 

I just checked all the chips with the old superpro2000 and saved all OSCCAL values to a file. I am now convinced that IF the values are off it was not me. I tried overwriting OSCCAL on purpose and not even the supepro programmer would overwrite it. Gonna recalibrate the "bad ones" and see what happens. I'm happy with the outcome of this venture, PSX backups direct boot with the chip and PS2 backups direct boot with FMCB.

 

Ok guys I found a modded version of the code, if the console is turned on by pressing the button 4-5 seconds the chip is disabled which allows originals, if it is turned on with a "normal' press the chip is enabled. Booted first try. I made SCEE and SCEA versions. This is my first attempt at porting anything or even doing anything in assembly. If anybody wants to test it let me know. Just tried it with FMCB, inserted a ps2 backup, turned off the console, turned it back on by pressing longer than 4 seconds and everything went fine. I guess no need for the switch now and can be installed internally too since it's controlled by the reset button. For USB a jumper between pins 1 and 4 is needed so it can detect the reset. Internally it connects to the reset point on the board.

 

original psx games arent work if the chip is enabled??
but still the switch needed for 2 reasons
1 i have read a long ago if the chip sends all the time the scex signal the laser is stressed (but this maybe a false staitment)
2 antimod games wont work if found a chip unless they are patched (this is 100% true)[/QUOTE]

 

Originals do not work if chip is enabled.
It does send the signal forever when enabled.
This chip is not multimode/stealth, the most protected game out there was Spyro 3 YOTD and there is a patch for it. Also there are patches for EA games, Dino Crisis, Coolboarders 2001, The Emperor's New Groove and so on. I don't play any of those LOL...
You can use the switch on this one also. It just has that extra feature and it did improve boot times, also 2 of the chips that would not work before, work now. Maybe a delay issue... This one has more delay routines from what I see.
BTW I also ported it to 12F683 if you wanna give it a shot.

 

sure i will give it a try i have nothing to loose. stealth games like those you mention they will work without a patch as soon the chip is closed. if i remember correct the right time is when you see the ps logo

 

You can download them already patched and avoid the hassle.I guess I'm just lazy... LOL... BTW I tested the PSX Gameshark backup and it works great Loaded Gran Turismo2 with 999,999,999,999 credits LOL... I assume in your region you use Action Replay, I guess that backup should also work...

 

yes in my region is action replay. but what about the other is the lesser stressed if the chip is give the signal all the time?? (if this is any true at all)

 

I don't know if the string is injected to the laser to be sent to the board or if the info is injected to the board directly which makes more sense (tap the bus and inject what is needed) after all it is the console that needs to check the string not the disc. Again I don't know...

 

anyway they just donate me a slim 90004. its the very last slim model.it had a bad lens but with little pot calibration its like a new. so when I get the pics I will test the latest model

 

ok i have the picks they are in antistatik bag thease one are made in thailand @Mord.Fustang prepare the hex when you have time. remember is for pal scee and for 12f683 @Apexseal i will test and the one you give me. tomorow is the day.

 

YES YES YES I can confirm that this mod is working up to latest slim ps2 I used th one @Apexseal give me. thanks goes to @Apexseal for remind me that. I was 16 at the time neokey released. thanks go to @Mord.Fustang for porting this to newer picks (I still want your port)
thenks also go to @rama for his testings.

 

Here's the 12F683 port with region-specific Hex's as well:

Remember the 12F683 version hasn't been tested yet.
edit: confirmed to work by @truemaster1

 

its working the games boot first try thank you

 

Awesome!! You're welcome

 

This is great!

 

Here's the Modded Version that uses the jumper between legs 1 and 4 for detecting the reset button.
To play psx backups just turn console on as you normally would.
To disable the chip just power on the console by pressing reset for more than 3 seconds.
Reset during gameplay resets game but keeps chip status.
Power off clears chip status to default (playing backups)

Region Specific Hex files included.

a good modification will be:
1 if reset is hold more than 4 second chip turn off. if reset pressed again it will stay off. it will be on after full close and restart
2 if the console turn on without hold the reset button chip will be on. it will turn off after 10 seconds by it self. it will turn on if reset, or by detecting tray open close again for 10 seconds. (too bad that i buried my chip in my console and put a tape on it to avoid any sorts)
but i have a 2nd fully operational slim ps2 so if this can happen i will buy a pic to test.

 

Chip does turn off when reset is held for more than 4 secs.
Chip does keep it's previous state after reset is pressed.
Chip will be on next time the console is turned on (default).
For the tray and others it will need something like the 'EA" mode but it will need more wires, this would eliminate the USB install.
I think I can do the turn off after x amount of time. But it will take me some more learning LOL... Which is not bad for learning purposes.

 

yes you've made o good job in this!!! about the timer I said to be placed in the hex code is about the chip to be stealth. and the wake from disk tray is about disk swaping. but I'm lucky in europe the games don't have antimod protection even if you boot an unpatched ntsc-us game in a console that haven't a stealth modchip the protection isn't triggerd. the protection we have here is called copy protection (libcrypt) and this have nothing to do with modchip.if your game isn't patched or don't have the exact subchannel of the original disk it will hang. even if you use a swap method to boot your game on unmoded psx-ps2. but in your region the games have antimod protection and it will trigger on ntsc-us console. so a chip that have timer is good for a us consoles
