since some games are getting close to 20 years by now and most of what you can find on web are iso/mp3
and after all like with SEGA ther's not that many CDs

I have a PCE CD, but it's totally strange.
Track 1 is audio, track 2 is data, then all audio tracks, final track is data again. And there are 3 seconds pregaps before data tracks.
AFAIK there is no copy protection on PC Engine CDs (correct me if I am wrong), so dumping discs for this system shouldn't be a problem. There is another issue though - multiple data tracks - but is it a problem for an experienced dumper? 
Same for PC-FX and PC-FXGA CDs, btw.

so that would be great then 
i have some cds too, and i got some more for sega so i'll submit those meanwhile
and even if those odd gaps will prove to be incorrect later i think it's still ok, sector or 2 off it's not that bad

I think that would be great if they would, it would be nice if they could have a misc system part to hold the older games till they rise in number as I am in the process of getting the older systems 3DO, Jaquar, Phillips CD-I, Neo Geo CD and turbograph CD etc. and it would be nice to be able to post good dumps here.

it is.. if 2 dumpers get the same wrong result thanks to EAC, there's no way to tell if the dump is incorrect later on

yes, i understand your concern, that issue with no gap on 2 tracks, the result would be data lost, ok. but i think it's some eac internals. on psx i would get it correct on 1 drive from 3 and it can be verified with sector viewer and also full cd size would always match so i think it's ok. but what i mean is, i think ther's those all 2sec gaps and one 1.74 and oddities like that on this system but even if it's later proven to be wrong, like all gaps should be even, data would not be lost, only shifted, would it not? so existing dumps could be easy modified should such a need arise. and like 99% info can be verified until then so it's not lost like part of tapes and floppies are now.

Definitely there's something fishy about those 1.74 pregaps. If you give a look to SegaCD dumps, EAC reports regular 2.00 pregaps for discs with low write offset, but when the write offset is some crazy huge number then 1.74 gaps start appearing. Maybe EAC simply doesn't go along with huge offset discs.

also in usa mega cd disc format specification it says pauses should be >=2sec. and somewhat strange thing is for example with 1st cd: G-6001, spliting tracks by detected gaps cuts data in half but if not detection is used pauses align nicely at the beginning and end of each track. still i think no data is lost, total size of audio tracks differ only by postgap but it's always 00, isn't it? so like if all tracks were put back togeather in img or bin no matter what gaps was full crc would be always the same. only cue differ.

You can find lots of unopened retro-games in Japanese stores - just look at FDS dumping on No-Intro's forum, and most of the items in this shop are located in Japan.
there must be some way to dump them correctly
PSX'D OFF!!
So can we add a PCE-CD section? Now that I can use PerfectRip I can rip that odd CD too.
Somebody should try to contact with necstasy.net owner, he should know some tricks and possible issues in PCE-CD dumping.
I added my first PCE dump
Things to note:
1) cuesheet is manually edited based on gaps reported by EAC: since the CD layout isn't standard at all, EAC doesn't automatically list all tracks in the .cue, but only the first audio track, while PerfectRip gives an error on last data track, so it doesn't save the .cue
2) I dumped both data tracks with IsoBuster: I resized track02 by 2:00, which is track03 pregap
3) both data tracks have a 2.74 (526848 bytes) pregap I attached using psxt001z, because IsoBuster doesn't dump pregap before data tracks: this way the total sector count of the dump is right and matches the actual CD

gigadeath, could you please give a list of games you dumped. if i have some of them we could compare again early on like with sega to avoid possible errors.
Only Human Sports Festival. That's the only disc I have.

yeah, the same here, everything's as you said
and cdrwin fail too on full scan, but on quick gaps differ a bit 
and cdmage won't open
offset: -1341
not sure where to look for date

umm, it does not work for me
Disc with ID "2030" doesn't exist.
also there is no PCE section on drop down, but when i go to
http://redump.org/discs/system/pce/
it says: No discs found.
The dumps match, I hope Dremora will make the PCE section public so everybody can see it
