How consoles like PSP are decompressing that format, by software or hardware? As of now, no hackers fully reverse engineered the PSP's Tachyon, only partially. I guess the decoding is in Virtual Mobile Engine DSP, inside Tachyon (the PSP main CPU SoC IC). Not only PSP uses this even the SONY Walkma...

Hi nocash, is there a way to save the whole cdrom tree view content in Filesystem viewer as .TXT? Just for bug reporting purposes? So we can send you the undocumented unknown formats inside the cdrom? These are the bugs I encountered in the new versions of NO$PSX and PSXTNY emulators. Tested in Wind...

Awesome, thanks to this new update and the useful infos newly added in the documentation of CDROM File Formats. News release notes 20 Aug 2022 no$psx v2.1 help: bugfix: bios C(03h) SysDeqIntRP is working (it's messy, but not bugged) Is there a missing info in between the colon(:) of help and bugfix ...

I tried the no$gba/no$psx test versions, but there's no crashing and task manager bugs in my Win10.

There's a stuttering audio bug in no$gba with NDS game.

Thanks for supporting CHD format!! It's working fine.

I can't read the bug report on the github page... and the post that you've quoted doesn't mention any bugs? The CHDMAN didn't want to accept the CDI/2352 track in a CUE. The error message is "ERROR: Unknown track type [CDI/2352]. Contact MAMEDEV". The workaround is to change the CDI/2352 ...

For tracks, is there a difference between "MODE2" and "MODE2_FORM_MIX"? The sentence "including the sub-header" is just there for confusion (it's pretty much impossible not to include the sub-header in those sectors). According to claunia's source code MODE2 is FORMLES...

Do you know a way to create or test CHD files with subchannel data? If you mean like the .SBI, I guess it's not possible. You need some external file, you cannot store it inside the .CHD. http://forum.fobby.net/index.php?t=msg&goto=6645 For PS1 games protected by LibCrypt, normally you have SBI...

Another annoying bug of CHD/CHDMAN.

Okay these are the CLAYS CHDs including DIR.

Unrelated to .CHD but for .ISZ format. Some missing information about .ISZ format in your website. PSXSPX CDROM Disk Images Other Formats .ISZ This is reportedly a "zipped" .ISO file, using some unknown compression format (unrelated to pkzip .zip file format). .ISZ is made by UltraISO EZB ...

I guess that's the Rest Home by Paradox?

The ZIP contains:

I got side-tracked and spent some days on LZMA2 and XZ decompression, whatever that's good for. Nice, it can be use for 7z and for the successor of CHDv5. What I am looking for is a test file with values smaller than "2352" (aka 930h). Okay noted, I'll try find that. I can't see the resul...
