Doesn't seem to compress normal cd isos #6

Closed i30817 closed 9 years ago

i30817 commented 9 years ago

Trying in wine to compress with maxcso Phantasy Star Generation 1 and Phantasy Star Generation 2, which are remakes of the originals on the ps2. Apparently these were released on normal cds, not a dvds. PCSX2 plays the isos.

Maxcso produces a 0 byte file on these files.

It doesn't spit out any error? That's unusual.

What's the exact size of the source files?

PSG1 is 72,9 MB (72857904 bytes) (the fan translation) PSG2 is 108,1 MB (108064992 bytes) (also the fan translation)

both isos

Also i'm using wine. No error message besides the usual messages in wine: fixme:ole:RemUnknown_QueryInterface No interface for iid {00000019-0000-0000-c000-000000000046} fixme:winsock:WS_EnterSingleProtocolW unknown Protocol <0x00000000> fixme:winsock:WS_EnterSingleProtocolW unknown Protocol <0x00000000> fixme:ver:GetCurrentPackageId (0x471e500 (nil)): stub fixme:ntdll:NtQueryVolumeInformationFile 0x58: volume info not supported

72857904 / 2048 = 35575.1484375 108064992 / 2048 = 52766.109375 72857904 / 2352 = 30977 108064992 / 2352 = 45946

Only mode 1 discs are supported. These are mode 2. You should be getting an error ouputted to stderr.

As discussed in #3, mode 2 is not a power of two and isn't supported. It could be supported by maxcso, but all other CSO software (including all emulators I know of) require power of two also.

I'm going to close this given the things mentioned in #3.
