PSX DIY ModChip Guide ?
How many wires does the modchip that is currently installed have? If it has four or three with an additional linked wire, then it is probably the anti-modchip function in the game that gives reaction.
You would need the MultiMode 3 hex that you can get from eurasia.nu. I think "Stealth IV" is just a commercial name for it. And the 12c508a can only be programmed once. NTSC games work on any chipped console in 60Hz, at least if you're using an RGB cable.
I would also recommend using a low-wattage soldering station instead of just an iron. The Aoyue 938 is quite cheap and really worth it. Many soldering irons can't heat from the tip but only from the sides, which makes it a lot harder and often gives bad joints (or maybe it is just me who has a bad experience with irons).
Are you really confident with a soldering iron? Because if not, removing a modchip can be a dangerous procedure. The components that the wires are soldered onto might loosen along with the solder and wire as well.
I would consider re-chipping the console just because it has a non-stealth chip to be rather unnecessary, even bordering ridiculous. Just burn ImportPlayer on a CD-R and boot the anti-mod game with ImportPlayer first (make sure to check the option "Anti-Mod Killer = ON"). Or you can just patch the game or download the game as a ROM that is already patched (of course you need to own the original for this, since I'm not sure if piracy is allowed on this site). Consolecopyworld.com is your friend.
Then you most likely already have a stealth chip. It is probably a different MultiMode than the diagram you used. I can only find one diagram for the SCPH-9002 though.

It might be that the program or even programmer you're using is not compatible with 12c508a. Not all programmers are compatible with certain PIC's, as far as I know.
4. I just like to plug'n play. And Dino Crisis IS one of my favourite PS1 games.
Besides that, I have already tried to make a mm3 chip but didn't succeeded because I don't know anything about programming PIC's...
So it's kinda bugging me that I wasn't able to do it...
I just want to burn my own chip... It will make me feel happy
1. For sure the one I've found and used myself...

Today I searched again on the net and found out something about 12C508 not having an ID and something about "OSCILATOR CALIBRATION VALUE" -> This is exactly where I need help from someone who knows about those things and which hex can be programmed on this particular chip...
Here are the diagrams for the 900x series
I just tried all three 900X diagram combinations (I have one more besides these two above) and none of them pass the anti-modchip protection of the game...

So back to the first track -> anybody has some info on how to burn a Stealth4.hex on a PIC12C508A ?
The third diagram in the pic below:
Sorry if this is a useless contribution but I have a 4 wire modchip (unknown hex or chip) connected to a PAL SCPH-5502 (underside), I've never had any issues playing any games on it so far including dino crisis 1 & 2.
Perhaps there is a 4 wire which can handle these games, unless it has something to do with the fact it's an older model PSX.
I'm one of 'em, I loved hammering the PSX (I went through 3 lasers in 5 months ). The games on there are varied, colourful and original. Love it.

PS Jailbreak Compatibility:
Looking for any PS3 firmware, see here:
4-wire ModeChip, a switch is connected to pin 5 & 6 which is used to enable/disable the ModChip
When trying to load a protected game, first turn on the ModChip and then turn it off after the white screen disappears.
Here is the diagrams for Mayumi/Stealth 4

1. Never heard of such a chip -> 4 wire stealth... Maybe you patched the images... or in case you downloaded them it's possible that the images were already patched.

A PS1 + HDTV = TOTAL CRAP! That's why I lost about 2 weeks trying to fix and old 21" CRT TV that was hanging around broken for about two years...
PS1 + CRT SDTV + RGB CABLE = PERFECT!
1. I know about that method but I like the "hard way" I just want to burn myself a functional chip of my choice...
