Topic: about ps1 libcrypt Japanese games

http://redump.org/disc/3033/

I posted Ultimate Fighting Championship (J) with sectors.log.
Because, Ultimate Fighting Championship (J) is libcrypted, it's included in this list.
http://axs00.hp.infoseek.co.jp/tips/rhp.htm (RHP="Red Hand Protection") (Japanese)

How can I know surely it's libcrypted?

Also, I wonder why DDR (J), FF8 (J) are treated as no-libcrypt. They're famous for their protection.
http://redump.org/disc/1562/
http://redump.org/disc/1422/

especially for FF8, all europian version have libcrypt sectors.
Or, no Japanese game is libcrypted, and RHP is not libcrypt??

could you add it again? hmm I deleted the libcrypt sectors information when I added the dump

Re: about ps1 libcrypt Japanese games

How many sectors does japanese libcrypt contain? I suppose only these sectors contain protection?:

Re: about ps1 libcrypt Japanese games

hmm... I don't know.
I don't think the protect is different by regions.

i took sectors.log again.
and, it looks like only 2 sectors are in common...

From your assumption, only 09:47:34 is the only libcrypt sector??
Well, I check it on another drive tomorrow. :\

Re: about ps1 libcrypt Japanese games

i've sent several subcode files from games that were listed as protected (also FF8, DDR) to Dremora at the end of the last year and he didn't find anything.
so i guess Red Hand is only an antimod protection. when i boot PoPoRoGue with chip on, it would  display a red hand sign at bootup, right after Sony logo and halt:
http://img367.imageshack.us/img367/2862/vlcsnap9966qp6.png
[SCPS-10020] Omega Boost
[SCPS-91208~9] Wild Arms - 2nd Ignition [PlayStation the Best]
[SLPM-86222] Dance Dance Revolution
[SLPS-01880~3] Final Fantasy VIII
[SLPS-01990] SaGa Frontier II [1of2]
[SLPS-02180] Dino Crisis
display a short warning message:
http://img329.imageshack.us/img329/4274/vlcsnap17089vd7.png
it's very similar to the USA anti modchip game message Pepsidrinker posted below
i can boot a copy of such cd (without subcode) if chip is disabled right after logo. though it would not start (reread cd forever soon after) but it was burned @16 on very old cdr so it's nothing strange. on emulator runs fine.
[SCPS-10033] Pet in TV [Limited Edition]
[SCPS-10109~10] Chase the Express
[SCPS-10112~4] PoPoLoCRoIS Monogatari II
[SLPM-86500~1] Dragon Quest VII - Eden no Senshitachi
[SLPM-86627] Dino Crisis 2
[SLPS-02728] Breath of Fire IV
[SLPS-01991] SaGa Frontier II [2of2](Square's Preview Vol.4)
boot up with chip enabled

would PAL lc protected games emulate without subcode?

Re: about ps1 libcrypt Japanese games

http://redump.org/disc/3033 I think these 4 sectors are definately not errors.. 2 of them xor to 0000 and both pairs are 5 sectors distance, this is common for libcrypt.. I think emulators don't circumvent libcrypt but it could very well be that there's an anti modchip protection that kicks in directly and also a libcrypt protection that doesn't work directly but only ingame..

Re: about ps1 libcrypt Japanese games

No libcrypt here.

2nd XOR == 0000 just means that sector has no errors according to CRC-16.

It's because psxt001z reads only 64 sectors where protection may be found.
It this case data was read from the next sector (common reading error for subchannels): 59 instead of 58, correct checksum fir the 1st and 4th sectors. 2nd and 3rd sectors, however, have errors in CRC-16 (most probably reading error).

Re: about ps1 libcrypt Japanese games

found a stash of old CDRs and spent it testing DDR little more. it had FLAGS DCP for every track, wasn't included in db, i guess i overlooked that. but it does not seem to matter. i've burned with and without on CDRWIN (no subcode) and could complite 3 stage game on both. it's whole game - until credits. i guess it's ok, at least this one. also i think ther's nowhere subcode mentioned on Japanese sites describing RHP. but maybe they define problem differently from USA/EU people, maybe they just want to play original CDs from different region - not backups.
also i think i've read somewhere that there was some problems regarding early protection schemes in Japan. i think it involved PoPoLoCRoIS and I.Q. and first releases were taken back because some unmoded consoles could not run protected CDs properly. and when you think of it, it may be true, since Japan is the origin region of PSX so there is most early console versions. so maybe they dropped subcode level cp in Japan completely, and only those few very first cds remain?

offtopic:
btw Alcohol 120 can't burn our .CUEs even though it mounts them correctly. it ignore FLAGS and set pauses between audio tracks to 0 - messing up TOC. such copy did not work. it boots and i can bypass red warning switching off chip but when song is selected and game is about to start it says: FAILED 'CD ERROR'.
since CCD can't burn .cue and EAC - data tracks, i guess maybe that leaves CDRWIN as sole program that is capable to produce copies from our backups?

Re: about ps1 libcrypt Japanese games

i guess, if you can not turn off mc, while running, you'd have to disable protection routine by code or patching backup image.
please try to googe for 'rhp xps' or something alike.
