Just another hexadecimal viewer and editor. Coded a new one because I got tired of old Discpac, which has issues on modern setups.
Currently for files, floppy disk A or B, ST-RAM, ST-Cartridge, TOS-ROM.
Can run as application or accessory.

Comporte quelques outils additionnels :
– fractionement/recombinaison compatible TC,
– gestion des images disquettes MSA et ST,
– gestion des fichiers PKZIP (méthodes STORE et DEFLATE).
Les fichiers .zip, .msa et .st vont vus comme des dossiers classiques.

Another GEM port of Magnetic Scrolls games Interpreter aka Magnetic 2.3 by Niclas Karlsson & co.
This program is not packaged with games, please download your beloved ones from the bottom of this page. *.mag and .gfx files are only handled, advise is to copy them in the gemagnet.dat\library folder.
Needs LDGM cookie for the GFA to load the MAGNetic EMU library (LDG.PRG provided in the archives).
Needs EdDI cookie for offscreen VDI (with VDI implemented) to display pictures. NVDI is strongly advised, standalone or above the fVDI/xVDI that handles the graphic card.
Intended for high-end Atari setups, with large screen and true colors modes. Needs 16 colors or more, but can run on monochrome mode without pictures. OK under FreeMiNT, but may be crashy under MagiC (sorry).
Original game GEMagnetic 0.8 by Dan Ackerman, program and sources, can be found in the archives of Magnetic 2.2 page.

Libraries using the LDG system, the GIFLib and the LibPNG.
Purpose for the GIF decoder is to obtain color table and 2d width*height array raw colors indexes data of the image (=rasterbits, =chunky mode). This avoids c2p+p2c two steps convertions in P2SM image tool, thus quicker. This is also convenient for games to load sprites, recolor them as wanted, and avoid to convert from TC24 bitmap (generated by classic decoders) downto 16/256 colors.
Purpose of this PNG decoder is to handle APNG specifications, meaning like GIF89a, animations are possible, storing several frames into one only file. Convenient for tileset store.
Here are listed versions for 68K, 68020-060 and ColdFire V4e using cross-compilation and the mintlib. Safe LDG.PRG is provided to install TSR ldg functions and the ‘LDGM’ cookie needed for my applications.

Here is a modest proposal for the V4SA, based on my own setup. My purpose is to use a simple and stable, clean and tidy GEM environment for my GFA coding: have to discard my own bugs from unsafe/unverified softwares. So few applications, the only I could use everyday. My own apps seem to run without a hitch, so they are present in number here. Sorry about that, please complete and test one by one with other softwares you want to use. Continuer la lecture de Fēng Shuǐ distro for GEM use
Graphic effects coded for pure VDI. You can alter these effects by changing the values in *.inf text file or modifying the GFA code using GBE.
