Hi guys, whats the latest in PS1 modchips? Is there any sort of universal solution? I have some PS1's I want to mod and then sell on, I have a programmer. thanks
I use stealth 2.8a for 100x as it allows you to play stealth games, you just have to hold reset which changes "mode" (which is just a delay it uses before disabling the chip, rather than detecting when it should disable itself) Ans also, you missed ONEchip for pal psone
mayumi v1 and multimode v2.x (are the same code) are the evolution of the old stealth 2.8a. Yeah, you're right, Onechip for PAL psone XD. To be onest for pal console it's good also the classic oldcrow 4 wire (latest revision), because the aren't any antimodchip protected games in PAL region. Only libcrypt. Plus the antimod protection don't work on PAL console, meh....
I see no mention of the holding reset to change the delay in turning the chip off in any of the mayumi or mm documentation I have, only stealth 2.8a. And most people tend to play ntsc versions of games in my experience, so that means you need stealth chip.
v2.01 - This version incorporates the standard 4 wire code along with the "Mayami" (error in the readme?) code and the old 'Dino' mode code. (example picked from the old dead official site) With the latest REI or oldcrow code (not the stealth) NTSC antiprotection don't works on my scph9002. I've also read that some devs at the time have the order that antimod code must work only on NTSC consoles. I don't remember where i've read this. Maybe @TriMesh can confirm this
Is there a way to identify which modchip one has? Like a homebrew or something? I bought a couple of modded consoles, unaware of it. Never liked the idea because of laser wear and stuff. But to my surprise, these seem to be in really good shape (laser wise), although they need a new disc spindle. Not sure what models they are now but wondered how can I ID the modchip. Both are a 3-wire modchip and a (blue) jump wire. The only different thing I noticed was that it outputs an NTSC signal during boot, which I didnt even knew my tv supported. I've only tried a couple of pal original games on it (console is pal, I belive 500x model).
Thats for the readme, i still prefer the way Dino mode is activated on the stealth 2.8a though. And regarding stealth - I certainly had to change some old crow chips for stealth chips and all consoles were PAL. I dont remember the specifics though (what games, etc)
You can narrow down which modchip it is by looking at install diagrams for modchips and finding ones that match and also finding out which PIC it uses (12C508 in this case).
It's built into the later versions of the library - when it starts up, it checks the character after "Sony Computer Entertainment " in the boot ROM, and if its "E" then it doesn't carry out the check, and just returns. Since the library is common, this means that even a US or Japanese game will have the chip detection code disabled. But this is only for later versions - the original one that was in games like Dino Crisis didn't have this check, and would run on PAL consoles, too. This was mostly in Japanese titles, although there were a few US ones that shipped with it. Allegedly the check was put into the library because SCEE thought that a "protection system" that blocked you from playing original discs was stupid.
