Add/Fix MAME CHD Image Support

[Enverex]

Some code appears to already exist for this (https://github.com/FrodeSolheim/fs-uae/blob/master/src/archivers/chd/chd.cpp) but I've tested by CHD'ing a CD32 disc (Zool 2) then running it but I didn't have any success - it just sat on the Amiga CD32 screen with the picture of the disc.

No output on the terminal regarding the disc at all.

This would be a useful addition to FS-UAE. A bunch of emulators have added it recently, probably because it has fantastic compression, only creates a single file (no bin/cue or cue/wav/bin mess, etc) and is usable "in-place" in that it doesn't need to be pre-loaded or extracted before use. Space savings are also pretty significant, in this instance Zool 2 compressed from 420MB to 198MB.

For anyone wondering, here is a comparison of the standard BIN file image and the CHD version (both are usable as-is and don't need to be modified or uncompressed to use).

It's been a while so I tested CHD images once again today, but still no luck booting those. Is CHD support for CD images even considered? WinUAE has it but I would really love to stick to FS-UAE because it's such a great and beautiful emulator.

[rtissera]

@FrodeSolheim look at https://github.com/rtissera/libchdr to support CD/CHD for CD32/CDTV systems. If there is interest I could add hard disk support too even that's a bit of work.

[a8bit]

Any news on CHD support yet?

Those old Amiga Aminet CD's really take up a lot of room!

[a8bit]

Amiberry now supports CHD for cd rom image, I think fs-uae is one of the last to add support for it.

@FrodeSolheim maybe some of amiberrys code could be useful for fs-uae?
