Un commentaire

See snapshotAnother 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, *.gfx and *.hnt files are 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.

Original game GEMagnetic 0.8 by Dan Ackerman, program and sources, can be found in the archives of Magnetic 2.2 page.

P2SM

Means « Pixels to Sprites & Masks »: image tool dedicated for games development (2/4/16/256 colors sprites). Work is done on chunky two-dimensional byte-array, so that image modifications are made independently to current screenmode.
Can be used as plain drawing tool for oldschool pixel artwork.

Needs EdDI cookie for offscreen VDI (NVDI), plenty of RAM and strong CPU.
Uses a customized PARX.SYS, provided in the archives.

The program can use the GIFdec.ldg and GIFenc.ldg libraries to speed-up GIF loading and saving and support GIF89a extensions (transparency, animation).

– 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.

– handle MSA and ST floppy disk images,
– split/unsplit files (TC compatible),
– handle of ZIP archive files.
.zip, .msa and .st files are seen as classic directories.

The program uses the Deflate.ldg library for PKZIP and Dosfs.ldg library for ST/MSA files.

Map editor dedicated dedicated for games development (2/16/256 colors or true colors). Tiles are imported from GIF or PNG and asset is stored in GIF89a or APNG containor.

Needs EdDI cookie for offscreen VDI (NVDI), plenty of RAM and strong CPU.

The programs MAPEDIT and its tool MAKE_MAP (GIF|PNG slicer) use the GIF & PNG codecs .ldg libraries to manage GIF and PNG file format. Please install these accordingly to the LDG way.

GIF & PNG codecs .LDG

4 commentaires

Libraries using the LDG system, the GIFLib and the LibPNG.

  • GIF codec is used by:
    – P2SM (since 1.4) to load/save GIF static images more quickly, to handle transparency and animations.
    – MapEdit to handle GIF files,
    – and its MAKE_MAP tool to slice a large GIF image into tiles and map,
    Other applications and games can use it, please read the HYP guide and P2SM GFA sources (gifdec_*/gifenc_* functions) as exemple.

    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.

  • PNG codec is used by:
    – MapEdit (since 1.3) to handle PNG files,
    – and its MAKE_MAP (since 1.2) tool to slice a large PNG image into tiles and map,
    Other applications and games can use it, please read the HYP guide and MapEdit GFA sources (pngdec_*/pngenc_* functions) as exemple.

    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.

See snapshotMeg est un vérificateur automatique de boîtes aux lettres et un filtre de courriers. Nécessite la couche TCP/IP STinG ou MiNTnet+GlueSTiK. Conseillé pour un environnement multitâche moderne type MagiC ou MiNT et une connexion permanente à Internet. Il est possible de se connecter en mode sécurisé avec une librairie SSL/TLS.

Meg is a checker and email filter for your POP3 and IMAP4 mailboxes. Need STiK or MiNTnet+GlueSTiK TCP/IP Layer. This program is based on the study of Kellis’ POPGEM.

The program needs:

Fēng Shuǐ distro for GEM use

3 commentaires

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 →
