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. :\

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..

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?
