PS1 Modchip Which ONLY Circumvents Region Lock?

    So in my downtime I've been reading through all of the Acts of Gord, love these stories! In short - It's tales of a guy named Gord who worked at a game shop in the late 90s/early 00s. However I just stumbled upon one story in which he stated that his store installed modchips in PS1 consoles which only disabled region lockout, but did not circumvent anti-piracy measures. The exact passage is this:

    "The most common variant of "mod chips" are the ones that also nullify the copy protection scheme in the machine. For some strange reason, this is a very popular attraction.

    However, as a game store owner, Gord likes the first reason and not the second one. A rather uncommon mod chip that he stocked was a mod chip that did only territorial protection removal. Most people would assume that mod chips by default removed copy protection. This provided many, many hours of entertainment."

    My question on this is: What type of chip would this be? Not looking to get use out of it, more just researching out of curiosity as every PS1 modchip I've encountered circumvents both anti-piracy and region lock. The closest I've ever gotten to that is a PS2 my cousin in the middle east owned which played all of his silver pressed PS1 and PS2 games, but not the CD-R backups we made. These of course were bootleg silvers, the ones that you can buy on the street in individual baggies for 1-1.5 JD a piece, although it's been years I'm not sure if that was the chip itself or operator error on our part.

    Its just the same as any other modchip, except it reads the first 3 letters of the copy protection data, then flips to an output to overwrite the last one.

    This way, only legit imports will work. It also bypasses all stealth checks too - as it knows when to send and stop sending data.

    Its called Anti Piracy Mod

    Huh, neat. So to accomplish that would you choose to not solder a few of the points from the chip's legs to points on the mobo? I'm trying to picture it in terms of a modchip floating out there like an MM3.

    Its 4 points, 1 and 8 for power. Then other two for injecting the data.

    It isnt MM3, its called Anti Piracy Mod - like I said in the first reply. Its flashed to the same PIC chips, but different code.

    That's quite neat, and I've never heard of it until about an hour ago! I had to look into Old Crow as I've seen his old 4 wire modchip for sale a few places, but I know that one can play backups as well as imports.

    Aside from a rental shop I've never seen the point in having this. Are some people afraid they might go to the dark side?

    Within the context of the stories with Gord - He owned a video game shop and wanted to offer a way which would let people play imported games but keep them all legit at the same time.

    I've been to plenty of shops overseas which offered to install modchips in consoles, but these are also shops which only sell bootleg silvers so it's in their own favor because their service is bootleg games and bootleg game accessories. If a legit store in Canada is selling bootleg enabling services then people would no longer have a need to buy legit software from the shop.

    By the way: This story has a part 2 :D

    Anti-piracy chips are inherently stealth as well. You can find the Hex files for them online.

    The second hex by The Old Crow did that. He has always stuck to the argument that his first hex only enabled piracy by mistake (and his own laziness when writing the original code).
