750x for 12F629 & 12F683

Give this a try:

http://www.mediafire.com/download/q01v5499u5zg7y6/750x+12C508+12F629+(region+specific).zip

Made separate region-specific ones (untested).

Edit: Confirmed to work on 12F508 by rama.

 

That was quick
I'll try them next time I have the programmer hooked up.

 

making them region specific it will boot the backups first try. thanks mord fustang. 22 august is really near

 

I will order some 12f683 can you make a pal hex for that when you have free time??

 

Just open any hex editor and type SCEESCEESCEE instead of SCEESCEASCEI

 

that easy?? thank you

 

I fire a hexeditor I load some hexes but all I see are numbers no letters such us scee or scea. anyway if mord.fustang have free time I'm sure he will create one.

 

It won't work if you open the Hex file with a Hex editor - it will be all numbers as you wrote.

You can easily edit the .asm file though (in MPLab or even Notepad) and change them all to SCEE and then compile it. But I can do it myself later.

 

The region specific 12F508 works very reliably. Boots every time

 

Awesome! Glad it worked.

 

Strange, I'm absolutly sure about it cause I had edit that string into the MM3 firmware by using PICpgm or K150 software. Thought it will be the same...

 

Well, in those programs the code would show up with SCEASCEESCEI or whatever, not sure off hand if you can edit on-the-fly with them, but it would show up properly there. Open up a HEX file in a Hex editor and you'll see it's just numbers.

 

thank you. sure tike your time I don't even have any pic now

 

if this works for slim 77004 we can safely assume that this mod is for all consoles. now about this mod back in 2007-2008 the freemcboot released. it allows to play ps2 backups without the need of modchip, you only needed to patch your iso with esr and burn it on dvd media (even if the game was for cd) opl (open playstation loader) relesesed later and the user can launch isos from usb media slim and fat (I don't recommend it because usb is slow) or from the internal hdd. fat only, but in the slims ther are the solder points and with little soldering skills you can solder an ide adapter kit and you can attach an ide hdd it will work as internal just like fat model. but freemcboot lacks the psx backup compatibility. the only way was to play them as images from usb or internal hdd via emulator. (the best emulator is popstarter)
but the emulator is just that, an emulator. the combatibility isn't 100% and even the compatible games glich here and there. and some times you can notice slowdowns. so with this modchip which only requires to remove a capacitor and brige two points (as external usb) or solder 3 points (internal) this simple chip and the freemcboot is the best mod a ps2 user can have.

 

12F629 "SCEX" strings are represented like this : 4S4C4E4A, there's a "4" between each letter unlike 12c508 which are all together. The last letter of each string is located at 004A, 004E and 0052. I would just use Mord.Fustang's upload since it is already done and has correct checksum. But if you wanna do some testing in order to use a hex editor you need to convert to bin so that you can see the actual strings on the right side of the screen like when using the programming software. After done, save and convert back to hex. I have ventured into learning some asm basics and try to add a timer and make the chip "sleep" after 60 seconds so that it stops sending the string over and over.

 

ha right now I don't have a pic so I cant test anything. putting a timer it doesn't eliminate the need for a switch. lest just say for example you play metal gear solid, is one of the games that don't offer a save before disk change, how the disk 2 will boot with a sleeping chip??

 

Ok thanks for bringing that up!!! I'll just leave it as is... LOL

 

that's ok. the thing piss me of now is I contact the electronic shop and the automated tape say the shop will be closed until 24 august but before 1 week a person there said to me in person it will be until 22 damn I cant wait. yesterday I solder the wires to ready for the chip lololololollll

 

Well I have a bit of set back also. I have like 10 chips left and so far only one has worked... They all program and verify but don't seem to wanna work. With my luck I have a pack of duds LOL... I'm not using resistor nor led. Could it really be a pack of duds???

 

If you are using k150 programmer espesially with "C" series pic's you will get such results. If you are using another thing — I can't say, maybe some calibration missmatch or bandicap trouble.
