New features in CD-Box v2.20:
NOTE TO 386 AND 486 USERS: a nasty bug concerning mouse drivers and UMBs has
been fixed in this version. If you have DOS and drivers loaded high, and
previous versions of CD-Box hanged at startup, try this one!
Major changes:
- archives: .ARC & .ARJ support added
- sound formats: .MDI & .WAV external support added
- .VOC partial internal support added (as long as it fits in memory (no
nonsense about a 64 KB limit) - I'm working on a homemade direct
playing-from-disk technique to play sounds of any size. It works, but I
want to test it really thouroughly before release; I'll put it in the next
version).
- improved graphics & mouse cursors
- capability to swap all main memory into EMS, XMS or hard disk when calling
an external player - useful for huge .MOD files. See Swap= parameter in
part IV of CD-BOX.DOC.
Also watch out for changes in CD-BOX.CFG, about .ARC & .ARJ & .ZIP
Bug fixes:
- SHARE.EXE locking file and preventing archiver from opening it - fixed
- won't crash any more when title contains "unprintable" characters
Small improvements:
- impossible to click on a song button while a song is being played
- buttons & sprites managers upgraded (song scrolling should be faster!)
- auto-repeat for Rewind, Forward, Skip backward and Skip forward buttons
- pilot lights flash corresponding format when a song is selected
- better behavior on 386+ systems (I just upgraded)
- "CD-BOX" on reader lights up instead of .ZIP pilot light (may change later)
- .MOD bars are colored
- CD-BOX/D made more readable (only songs with errors stay on the screen)
- .VOC length (in seconds) directly computed from the file on disk
Known but unfixed bugs: these are not bugs in CD-Box (otherwise I would have
corrected them obviously) but in external players, that happened on 386+:
I've found that the .MUS player (PLAY.EXE) plays a hideous cacophony of
sounds, whatever the song, and the .ROL player (SPUTROL.COM) messes up the
system clock completely: either it speeds it up like crazy or slows it down
to a crawl. This happens even when running in plain vanilla DOS, so I know
for certain it isn't CD-Box's fault. This is why CD-Box needs more internal
support: to do away with these #&@$ external players altogether!
Also:
- CD-BOX.RSR doesn't exist anymore, and is merged into CD-BOX.EXE. You can
remove your older copy of CD-BOX.RSR, if you have one. Note: do NOT use
PKLITE or similar program on CD-BOX.EXE, or you'll reduce the memory
available to CD-BOX, maybe crashing it!
- I've added the French documentation (FRENCH.DOC).
- I've removed the "unregistered copy" message at startup... and considerably
increased the visual impact of the one when shutting down!
Coming attractions:
- I have an artist drawing a new title screen for me...
- Support for .LZH and .ZOO archives when I get bored
- maybe .MOD playing time extraction from the file on disk
- "Direct-from-disk" or "double-buffering" or whatever-you-want-to-call-it
technique to play .VOC files of any size (like Creative Labs' VPLAY
does). This one is homemade, I'm rather proud of it, it works perfectly,
just let me polish it and it'll be in the next version!
- I have high hopes for internal .WAV support, tweaking it and making the SB
think it's a .VOC file; it should be in the next version too!
- Also I might fool around with .MDI... stay tuned!
- Anybody out there got .MUS or .ROL routines I can use or get inspired by?
