This patch makes sam's = cmd output what seems to me a more
useful (plumbable) format: /full/path/to/file:addr , where
addr is line(s) under = and rune(s) under =#.
Some gba cartridges use flash chips produced by a few different
manufacturers for backup memory. A game rom may then try to read the
device id for its flash chip and break if it's the wrong one. There's
no way for us to know which chip is supposed to be there, save for
looking it up in some database. These chips are either 64k or 128k
big. gba(1) hardcodes the id for the SST 64k chip, but games like the
Pokémon ones use a 128k Macronix chip and expect a different id,
completely breaking them.
This patch sets a different default for 128k flash backups, and gives
the ability to set the exact type when creating the save file if it's
really necessary. This new default fixes the Pokémons. The type is
saved in the save file, but this will *not* break existing ones. It
may be that we don't need to worry about the type and just have an id
that corresponds to the right chip size, which is why these defaults
make sense, but I haven't tested more than a dozen roms, mostly since
I don't really know which games use 128k flash.
Untangle the lexer and interpreter thread state.
Fix the file and line number error reporting, getting rid of
Xsrcfile instruction, as the whole code block can only come
from a single file, stuff the source file in slot[1] of the
code block instead.
Remove limitations for globber (path element limits)
and be more intelligent about handling globbing by
inserting Xglob instruction only when needed and not
run it over every Xsimple argument list.
Remove fragile ndot magic and make it explicit by adding
the -q flag to . builtin command.
Add -b flag for full compilation.
Make exitnext() smart, so we can speculate thru rcmain and
avoid the fork().
Get rid of all print(2) format functions and use io
instead.
Improve the io library, adding rstr() to handle tokenization,
which allows us to look ahead in the already read buffer
for the terminators, avoiding alot of string copies.
Auto indent pcmd(), to make line number reporting more usefull.
Implement here documents properly, so they can work everywhere.
SSL is implemented by devssl. It's extremely
obsolete by now, and is not used anywhere but
cpu, import, and oexportfs.
This change strips out the devssl bits, but
does not (yet) remove the code from libsec.
g(1): sync filetypes list
the file types list in the 'g' manual was out of date.
this change synchronizes and sorts them.
it looks like the .B macro only accepts 6 args or less,
so observe that limit.
remove old /sys/src/games/nes/joynes in favor of joy(1).
joy(1) has more buttons for the other emulators; there is
no longer a significance in the order of the keys.
document nusb/joy, add information in each emulator manpage.
games/dmid uses the same sample rate as the chip for music, but other
applications do not. opl3 and its older version opl2 (not in 9front)
read an input stream of commands in basically IMF format, something
used in other id Software games and some others, which assumes a
given input sampling rate: 700 Hz for Wolfenstein 3D music, 560 Hz
for Commander Keen, 60 Hz for Ultima 6, etc.
The opl3 emulation on the other hand is not really intended to run at
a sampling rate different that the chip's 49.716 kHz sampling rate.
Previously, we assumed it runs at 44.1 kHz and just used the input
rate as a divisor to get the number of samples per delay tic.
From what I understand, the correct way to use it for accurate
emulation is to run the opl chip emulator at its intended sampling
frequency, then downsample to 44.1 kHz. This means better output
but more code. The alternative is to basically do the same as
before rev 8433, except with no buffering, but at accuracy/quality
loss. This change implements the former and just forks pcmconv to
deal with resampling.
this fixes real-time applications.
-n previously specified a rate divisor rather than the rate itself,
which was used for specific applications outside of 9front. instead,
just set the rate directly, more useful and straightforward.
