Docent wrote a decompressor the the LZ4 compression algorithm, which can be used on any Zilog Z80 CPU. The focus of the LZ4 compression algorithm is a fast decompression speed and a small decompression routine. The size of Docents version of the decompression routine is 219 bytes (raw decompression routine under 110 bytes) and it supports the legacy and the newest LZ4 format (except for framing).
You can download the latest version of the decompression code here or at the end of this news.
decompresses files packed by lz4 command line packer and raw lz4 compressed data
supports legacy and the newest lz4 file format (except framing)
fully relocatable code
total size of 219 bytes size with raw decompression routine below 110 bytes
cpc firmware friendly (no alternate register set used)
ROM friendly – no self modifying code or additional memory required
simple interface – only start of file in memory and target memory destination required
This archive features the LZ4 decompression routine by Docent, which can decompress files which were compressed with the LZ4 compressor by Yann Collet. Its advantage is the small decompression routine size and high decompression speed.
“Get The Cash” is a fast paced arcade written by Ross Simpson. The game is quite simple: you have to collect the money bags, which are falling down from the top of screen, and you have to avoid the brick walls, as well. While you are playing the game, it will get harder, because the playing field is reduced in size and you have to collect more money bags to reach the next level. The game is written in HiSoft Pascal, using Sean McManus Easy-Sprite driver. The intro is written in assembly language.
You can download the game from the CPCWiki and at the end of this news.
SAMdisk is a tool to convert floppy disks into various disk images which can be used in emulators. It works with almost all PC floppy controllers and supports also some copy-protected formats. It requires that you have fdrawcmd.sys, a low-level floppy disk driver, installed on your system.
SOS released a very useful utility for all users of ACMEDOS called YANCC (Yet Another Norton Command Clone). With YANCC you can manage the files, which you have stored on your XMASS or Symbiface II IDE drives and of course you can easily copy them between your floppy disk. Obviously the GUI is similar to the old DOS program “Norton Commander”, hence the name of the utility. If you want to use it, be sure to compare the version number of ACMEDOS with the one that YANCC supports.
You can download the latest version of this utility from the CPCWiki forums.
Nibiru is a new game for the Amstrad CPC written with the Locomotive BASIC extension 8BP (= 8 bits of power) by Jose Javier Garcia Aranda. Nibiru is a side-scrolling action game in the tradition of games like R-Type or Nemesis. You can download the game from the authors GitHub repository (you will also find the source code there) or at the end of this page.
