ai64: Batch archive extractor for IDE64 users

Posted by: Ferenc Veres on January 28, 2005 09:23:41 PM +00:00(55615 Reads)

ai64 allows you to comvert complete directory structures containing c64 programs into IDE64 compatible copy of the whole structure. For example try running it on a complete copy of Arnold Game Archive, before burning a CD for IDE64 usage. Most of the archive will be converted to prg and d64 files. The program is licensed under GPL v3.

Latest version: v1.4, released on 25th of March, 2010.

Demo Result

You can see a demo of what this program can make from the various zip, rar, zipcode, lnx, t64, d64 and more archive files on the FTP site.

Latest release: ai64-1.4.tar.gz (03/2009) (changelog)

System Requirements

Which makes it possible to run PHP programs from the command line. Normally part of all GNU/Linux distros, on Mandriva Linux it is the "php-cli" package.
GNU/Linux or Unix
Tested on Linux only. Windows compatible filename generation is now supported, Windows platform support is planned (never tested).
unzip Command line unzip to decompress the files.
unrar Command line unrar to decompress the files.
tar Command line tar to decompress the files.
gzip Command line gzip to decompress the files.
Zipcode to d64 converter by Marko Makela.
Marko Makela's converter masterpiece to handle all the c64 file formats (tested with v2.1.2).
c1541 Command line utility, part of Vice emulator (tested with v2.2).
[Not needed if you use Vice c1541] This is a little C program I made years ago, included in ai64 download.

What does it do?

The program will walk recursively in the sepcified source directory, convert all files to c64 usable format and copy them into the destination directory structure. Thus from all your ZIP, T64, etc files, you will just have a big directory which is directly usable on your IDE64 CDROM.

Currently the following formats are handled (anything can be nested, e.g. d64 in zip and so on):

not copied
DIZ not copied
ME not copied
not copied
not copied
not copied
not copied (D64 extraction dirt)
ZIP uncompressed and re-processed
extraced if 1 file only and BAM is valid. Hi-score  files - if identified - are ignored if there is only 1 more file. Some BAM validation messages in names/headers are taken into consideration.)
extraced to files (if there is a single file named "FILE" is inside, the name of the original t64 is used when saving it to prg.)
P00 extracted to normal files
PRG copied as is
TAR extracted and re-processed
GZ extracted and re-processed
TGZ extracted and re-processed
RAR extracted and re-processed
LNX converted to d64 and re-processed
ZIPCODE (1!,2!..) converted to d64 and re-processed

Files starting with dot are not copied (Unix hidden files, FTP site messages).

Not listed files: copied as is.

Support is missing for: BZIP2, LHA (lzh).

All the stored files are saved with characters which are readable on C64.  Filenames are converted to 16 + extension, IDE64 can handle this length (requires 0.9x or higher IDEDOS). Already existing files are not overwritten, the new file will get "-1", "-2".. index, thus running the program twice will create all destination files twice.

When the whole directory structure conversion is finished, ai64 will take another long walk. It will rearrange all the directories which contains more than 100 files, to make sure there are no more than 100 files in a directory (easier to handle on c64, MAN, etc). The created subdirs will be called "ai100-X", "ai200-X" and so on, where "X" means the first word of the first program in that dirctory. E.g. "ai300-blackjack".


Edit ai64 executable file if necessary:

  1. Customize the location of your php interpreter in the first line.
  2. Set the location of your d64list program or comment out that line to    bypass analizig d64 contents.
  3. Make sure the $tmp_dir is far from any important locations, because the  program will run thousands of "rm -rf" commands inside it (honestly, I create a "lion2" user just to run the program, you never know... especially while developing it.)  See ramdisk tip below.
  4. Customize the location of "cbmconvert" executable as well.
  5. Make sure the other decompress executables are on your path.
  6. There are some other configurations in the source's head.


  1. Collect the c64 stuff what you want to convert into a directory structure
  2. Run "ai64.php sourcedirname destinationdirname"

ai64.php [options] original_dir destination_dir

-s path/name Skip to this file before staring processing
(Use this to continue after something went wrong)
-x ,
Use ',' as file extension separator (default is '.')
-v Verbose, list succesfully processed files
-w Force windows compatible file naming
-h Print this help

If ".php" is not registered to your PHP interpreter, you may need to type  "php ai64.php" instead, assuming php.exe is on your PATH.

The conversion process of one CD (600 MB) takes a lot of time.

There is no warranty of any kind. So I advice again, to create a temporary user which cannot write your home directory, and run the whole conversion by that user!


ai64.php -x , -v -w c64/Demos c64stuff

Converts with comma as extension separator, windows compatible file names. Useful when copying to HD using FuseCFS (

ai64.php downloadedwares coolwares

Convers with dot as separator. Linux file naming conventions. Useful when burning a CD for use with IDE64.


Using Ramdisk or TmpFS

Since the program creates and deletes a LOT OF TEMPORARY FILES while uncomressing the archives, it is a good idea to choose a temporary dir (configred in the script) in RAM.

Using tmpfs (recommended)

mount -t tmpfs none /mnt/rd
chown lion2:lion2 /mnt/rd

Using ramdisk (more complicated)

Usually Linux distros have ramdisk by default, to find it see:

ls /dev/ram*
dmesg | grep -i ramdisk

The second one also displays the size, what you can configure with the "ramdisk_size=64000" (64MB) kernel parameter at boot time (bootloader config). I use the following small shell script as root, before converting:

mke2fs -m 0 /dev/ram0
mount /dev/ram0 /mnt/rd
chown lion2:lion2 /mnt/rd

Logging the errors

There is no option in the program to log the error messages, but it is very simple using standard Unix tool, "tee" (-a is for append, if needed).

ai64.php orig_dir dest_dir 2>&1 | tee -a errorlog.txt

Exisitng editors for text data DjVu files are quite limited, like for example DjVuSmooth. So I've implemented a new editor in JavaScript, that allows editing both the strucutre of the text (paragraphs, lines, words,...) and the coordinates of the text boxes by simply dragging with the mouse, features like create, delete, merge are also available.
