ZSNES spc player

will ZSNES even be able to play SPC or RSN files

Just write a SPC2ROM converter.

EDIT: j/k of course. Well, if there'll be a dev who will find this useful, maybe then this will happen.

RAR is inferior. JMA is also the best for SPCs.

Thank god for that. With storage going for the absolutely ridiculous price of up to 40 cents per gigabyte, we need all the compression we can get for 64kb files. Who cares that most applications (WinAMP, WinRAR, WinZIP, foobar 2000, etc) don't support the compression format?

There is actually a winAMP plug-in that runs SPCs and even RSNs called SnesAMP. I found it somewhere and it works perfectly.

Now find one that plays JMA compressed SPCs in WinAMP.

Note that I'm not saying anything bad about the format, it's obviously the best in its class. But it's completely unnecessary when we're talking about sixtyfour kilobyte files.

WRONG:
64 kilobytes
WRONG: = 64*((2^10)^2) = 67108864 bytes
RIGHT: = 64*((2^10)^1) = 65536 bytes

10 gigabytes (very conservative hard drive size)
WRONG: = 10*((2^10)^4) = 10995116277760 bytes
RIGHT: = 10*((2^10)^3) = 10737418240

163840 SPC files on a 10 gigabyte hard drive.

uncompressed obviously. the key here would be the difference in compression ratios compared from rar and jma and shit. I am not whipping out a fucking command line just so I can decompress spc files and shit to save even a few megabytes using jma. I will double click my windows finger all over and gawk at a winrar gui to listen to spc files.

and if anyone here has more than say 1,000 spcs uncompressed sitting on their hard drive, then you gotz some problems.

Bootgod's unofficial Super Jukebok 3.3 supports JMA.

The point being made here is that for ZSNES to play compressed SPCs, it needs to be in a format ZSNES can handle.

I believe RAR would require a separate library (which may be incompatible with the ZSNES licence, although I'm not positive), is a closed, proprietry format and would require additional coding. JMA on the other hand is already been implemented in ZSNES, is an open format and is definitely compatible with the licence. It also has superior compression, although this is not the biggest point in it's favour IMO.

What kind of math are you using? 64KB is 65536 bytes (64 * (2^10))
10GB is 10737418240 bytes (10 * (2^30))

oddly enough, the number of SPC files you can fit remains the same (163840) but the number of bytes you had are WAY off.

I like having the maximum storage for all my files. It leaves room for other content, whatever that may be.

Oops. My math was dividing 10 terabytes by 64 megabytes. One too large an exponent on each. Good eye.
