If you still take suggestions for stuff to add to the improvements folder, then mega man 8 and X4 with the undub, X5 with the improvement project addendum, and X6 with the tweaks patch would all be great to have, they're all on romhacking.net

This collection is great, is there a chance the translations will be reuploaded?

Love this set, as well as the legendary No-Intro collection you have. Thanks a ton!

Are you going to update it?

Yes, track 12 is wrong

Checksum for extracted bin file from CHD does not match redump (http://redump.org/disc/17873/).

Expected redump crc32 for monolithic bin:
d680c8c1

Checksum of monolithic bin extracted from chd:
6c3b3afc

Thanks so much this is next level work. Just wandering now that pcsx2 now supports CHD will you be releasing a chd rom set for ps2 roms?

Great job of converting every title to chd format... However, would it be possible to add Mizzurna Falls latest english patch on the translations folder ? (https://www.romhacking.net/translations/6027/) If so, it would be greatly appreciated, thanks !

Would it be possible for you to add the option to download these sets as individual ZIP files containing all respective CHD files similarly to the No-Intro sets? If so, could you do the same with the other CHD sets you've previously uploaded?

Broken torrent

Hey @ChadMaster, some isos such as Medievil 1 SCUS-94227 seem to be broken, I run some hash checks on duckstation and it fails.
Be well!

Will only add 3 torrents to the download list

thats all

One of the better PS1 collections in the wild.

Can the uploader comment on the status of both USA and PAL collections? From the top of my mind I don't see anything missing.

Hi ChadMaster, thank you for your hard work on these archives, you are a legend.

Are you willing and able to generate some DAT files for the CHD sets? I would like to verify what I have downloaded.

Many thanks,

Is there any way to scan all files using the xml file ? I load it with CLRMamePro and nothing happened, looks like the xml file is not recognized !

Good to see this. Hope Chouzetsu Daigirin '99-nen Natsu-ban gets added soon! Also, by any chance, could you do ps2 asia/Japan next? The only attempt at that is 2 years old and stopped at F.

@ChadMaster

That size limit isn't accurate information. I'd hold off splitting everything up. I have had this confirmed from archive staff.

@ChadMaster

No problem! Thanks for the No-Intro stuff.

@ChadMaster

Since you are going to CHD every REDUMP set me and @redump upload, make sure you don't miss titles.

...Iru won't show in the download/redump.psx #

There are already Redump PSP sets on archive.org, there's also a North American PS2 one from 2018.
PSP Sets:
https://archive.org/details/PSP_US_Arquivista (USA)
https://archive.org/details/PSP_EU_Arquivista (Europe)
https://archive.org/details/PSP_JP_Arquivista (Japan)

@ChadMaster

Thank you so much for all your hard work and effort! I've been trying to find complete collections like this for some time now.

I'm requesting PS2, GameCube, Xbox, PSP, and everything fun in the Redump collection when possible. Thank you :)

Does this dump only contain # - D disks?

Its good time to join CHDs dat files to redump .dat database :) This set is good point to do it :)
