    How do you fake the SCEI/SCEE/SCEA protection?

    fake? SCEx is reply to particular cmd. you can read no$ docs.

    Yeah, fake. As in "it doesn't come from reading a real CD". So you're saying the two wires that you solder to the cd-dsp are enough to do everything including the protection check.

    these 2 wires are not for protection at all. CD_CS and CD_INT. other signals are shared on parallel bus.

    to understand better chk how ps1 cpu interconected w/ cd-dsp for example cdx1815 (scph-550x).

    in short - yeah, these 2 wires modification and psio as cartridge on PIO - "are enough to do everything including the protection check."

    You've not answered my original question of how, whether you need an original in the tray or whether you're injecting something into one of the chips or whether you're avoiding the check. If you're avoiding the check, then how well does it cope with games that check after the program has loaded?

    no original in tray,
    no injection
    no avoiding
    just : psio acts like original cd-dsp. cpu send cmd to cd-dsp like GET_ID, cd-dsp send back a reply in which SCEx is stored. no matter when - before or after program has loaded.

    in no$'s docs you can find "cmd & reply" list

    How do you stop the original chip from interfering? Is it permanently disabled?

    I assume you only reply with SCEx when the virtual head is positioned where it's stored on the original discs, as some protection checks it later to detect a mod chip.

    CD_CS of cd-dsp cut off from the line, and pull-up.

    Did you gentleman plug the Ethernet cable to both the PS2 Network Adaptor and your router ? The PFS Wrapper does tty via UDP, so a linkage to the router/local network is required, otherwise the tty driver would return an error to the wrapper and the wrapper will halt the IOP execution (causing a black screen of death).


    POPStarter allows me to disable TTY via UDP and to load any driver after the IOP was reset with POPS's IOPRP. I tried loading Napalm's PL-2301 driver for the wrapper to print stuff in NapClient lol. It works... for a few seconds, then crashes. I bet it's because the host device buffer is to small, the driver also crashes when too many fio requests are issued by POPStarter itself...

    I was diggin the web searching something like this. Thanks a lot, Delcro! I hope this project comes to success, cause Ps2psxe (the only option for psx isos via usb) is pretty dead.
    It may be a little offtopic and mistaken (I have nearly to zero hack knowledge) but lately i played "Gunvari Collection", a namco compilation with the Point Blank/Gun Bullet saga and Time Crisis for PS2, released only in japan. Both from PSX. Wondering if they included some PSX emulator instead of porting those games to ps2 hardware... there are some weird load times for 32bit games runnin on 128 bit system. Would be great someone could confirm/deny this? If I remember well, POPS comes from a Bishi Bashi 3 for HDD demo or something like that so maybe(dreamin) this is the same thing.
    Sorry for spelling errors, english isn't my native language.

    EDIT: One week and no answer? c'mon pleaaase ;) just joking, i know you have a life.
    Anyway, I submit a couple screenshots from the Gunvari Collection iso structure. It seems that the SLPS_ ELF file search for those files in PROGBIN folder (game1,game2,etc). And take a look at those 1Gb dummys...
    Please, tell me what you think, anyone: could this be a psx emulator instead of a ps2 port?

    And sorry but i have a problem with the POPS usb patch. I patched the Execute.elf with american bios, tried Star Gladiator NTSC (reported to work in compatibility list) and only get black screen. The question is: do i have to connect the network adapter in order to play POPS USB? because i read something like that and i'm confused. I repeat that i know nothing about programming and don't speak english very well.
    Thank you for help, and hope to have popstarter rev13 with usb support soon :D

    I always try before ask to forums, the problem is i got no network adapter. its really hard to get one here. I made the question because i read something like that on this forum and, due to my english knowledge, ask if i understanded well or not.
    So: do i need one or it's possible to boot without it and means im doing wrong.(Ps2 fat model)

    Delcro, thanks for the great job done! Will the emulator fixes and improved? Everything works well, but PAL games are offset screen up. Sorry for my english.

    If you tried it and it didn't work and this "POPStarter allows me to disable TTY via UDP and to load any driver after the IOP was reset with POPS's IOPRP" doesn't help then then I would say you currently need a network adapter. I've been using a slim ps2 for years because the fat ones are too noisy and they all come with Ethernet built in, so maybe that is another option while you wait for another solution.
