Package ‘maptools’ - R

TIP a text transcoding cmdline tool - SQABase91 is like Base64 but better

String Quotable ASCII Base 91 (SQAB91) is a textual encoding for binary data streams.
I created the encoding for myself to efficiently store text color data for a text-based game engine. I could have used Base64 or ASCII85 (as seen is .PDFs), but wanted to build in better compression. My color data is highly repetitive and a gzip or similar compression routine is overkill when RLE would do. Rather than make this a one off block of code I turned SQAB91 into a full featured command line tool for use as a general purpose text transcoding.
I had previously used Base 96 encoding in ASCII Fold (a lightweight text compressor), but needed to reduce the character set to permit string quotable and HTML / XML safe output and tab / space / newline for formatting output lines. I found that Base 91 can store 13 bits in a pair of digits and wasn't overly wasteful: Two digits of Base91 represents 0 to 8280 in decimal, and 13 bits is 0 to 8191. Rather than let those extra 89 values go to waste SQAB91 uses most of these for Run Length Encoding (RLE), and the rest for end of bitstream trimming codes and one meta segment separator.
SQAB91 allows multiple data streams to be concatenated without decoding and encoding again: Just paste the two streams together and the decoder can read the two streams as one stream. A special value "!!" is a meta separator that operates at a higher level than the ordinary padding marks that terminate a stream. This allows multiple data segments to be combined and then split into separate files or streams later.
A lesser field separation mode (soft delimiting marks) can allow a stream to be composed of many smaller fields within greater frames separated by !! (hard delimiter mark). I use this feature for storing frames of animation data. Without these built in delimiters I'd have to arrange to include data lengths or escape codes within the input data itself. With the soft and hard delimiters SQAB91 is essentially a bitstream container format that could be used for multiplex stream data, such as streaming audio and video frames.
Here are some features that I feel set SQAB91 apart.

MAME 0.196

MAME 0.196

MAME 0.196, our March release, is here just in time for Easter, and it’s packed with all the goodness you’ve come to expect. In a very exciting development, Team Caps0ff have extracted the C-chip data for Volfied, Superman, Rainbow Islands, and most importantly, Bonze Adventure. This cleanly fixes some of the most long-standing emulation issues in MAME. The improvements to Sega Model 2 have continued, with Virtua Fighter 2 and Motor Raid now considered working. Other Model 2 games are greatly improved as well.
For fans of 8-bit home computers, MAME 0.196 has improved ZX Spectrum family emulation, fixing many graphical glitches. A QuikLoad option has been added to several CP/M-80 machines, allowing .COM files to be loaded directly after the operating system has booted. Emulated IEEE-488 (GPIB) can now be tunnelled over sockets, opening up the possibility to simulate peripherals outside MAME. Interpro progress has continued, and is now at the point where you can boot the rebuild floppy.
Other new working arcade games include Big Buck Hunter, an older joystick-controlled version of Ghox, and a rare unprotected version of Opa Opa. With some fixes to our vector maths, War: The Final Assault is working, and Gunpey has been made playable using decompressed sprite data extracted from a working board. New LCD hand-helds include Dennis the Menace, Double Dragon 3, Jurassic Park, Spider-Man, The Addams Family, The Flash, and X-Men - Project X.
In an emulation first, MAME 0.196 supports QSound DSP emulation. For now, it’s only enabled for the vgmplay driver by default, and it requires a fairly fast computer to emulate at full speed. It will be enabled by default when system requirements are a bit more modest. The SH-4 recompiler has been enabled by default for Dreamcast-derived systems, giving substantial performance improvements.
Of course, there are plenty of other improvements. As always, source and Windows binaries are available from the download page.

Datagram is mostly a synonym for packet. An application data stream can be broken into segments.
