Here's a GCW Zero vanilla port requested by Gab1975 of DCaSTaway, an Atari ST emulator by Chui, based on Castaway and Hatari, re-written and optimised for the Dreamcast and Dingoo (chui.dcemu.co.uk/dcastaway.html)

Changes made: Added Makefile.gcw, changed default directories, create emulator directory on first run, packaged in opk format. Source code is as always included.

HOW TO INSTALL

The emulator requires a bios file to work. I cannot include this file for copyright reasons.
It is recommended to use the "TOS 1.04 UK" rom for best compatibilty, however other roms should work.

1)Run DCaSTaway in order to generate the correct file structure in your home folder. It will tell you it can't find the ROM file and exit.
2)Rename the TOS file "rom" (must be lowercase and without file extension)
2a) If you use Windows ensure you correctly remove the file extension!!! Windows doesn't always show the extension...or simply use DinguxCmdr on the gcw instead ("SELECT" file, press "Y" and select "Rename")
3)Place "rom" file in the $HOME/.DCaSTaway/bios directory.
4)Run DCaSTaway, if all has gone well it will now run fine.
5)Select the disk image you want from the file manager menu. Default directory is $HOME/.DCaSTaway/diskimages so it's easiest if you place them there. DCaSTaway can handle compressed .zip files so there's no need to uncompress these.
6)Select "Run" to play!
7)Select SELECT and START to return to the menu. (press and hold SELECT, followed by START)

CONTROLS

There are three input modes in DCaSTaway, mouse, joystick and virtual keyboard.

The default mode is joystick. The controls here are the usual D-pad to move and A/Y.

Mouse mode can be accessed by pressing the left shoulderpad. From here D-pad controls mouse movement and X/B to click. Right shouldpad alters the mouse speed. Pressing left shoulderpad will take you back to joystick mode.

Virtual keyboard can be accessed by pressing right shoulderpad. Select the desired key with the D-pad and select with the A button. Again, press right shoulderpad to return to joystick mode.

ISSUES

1)Frameskip seems very fast, it's probably best to keep it set to auto for normal play, set frameskip to 5 if you want to skip boring intros.
2)There's some minor corruption of the mouse icon at the bottom-left of the screen FIXED
and occasional corruption of the virtual keyboard.
3)Some disk images don't work. I've tested them in the Windows build and they seem to have the same problems so it may be due to the engine or (more likely?) it's a bad image.
4)Y key doesn't shortcut to save as described in the menu.

1)Support for 640x240 resolution*
2)Removed vsync option from menu and replaced with the following:
3)Support for mouse emulation with analog mouse. If on will emulate the mouse, if off will emulate the joystick. DCaSTaway will remember your setting between sessions. Presuming you have a functional A-pad there is now no need for mouse mode.
4)Mouse clicks always accessible with X and Y. This solves issues with a few games (Action Fighter, Gods, Cybernoid 2 and others?)

*Keyboard, mouse icons and messages are at fixed resolution and it is not trivial to change these. Given the small number of games at this resolution and that the messages and keyboard is still legible I am inclined to leave this unfixed.

Bonjour

Je suis un newbee...
Je n arrive pas a faire fonctionner l emulation atari
J ai copier le dge sur le dossier apps
Rebooter
Ensuite le lien apparait bien dans les emulateurs
Je lance et vais chercher une rom
Petit temps de chargement puis retour au menu emulateurs

Avez vous une idée de ce qui ne parait pas aller
Merci !

Il faut que le bios soit installer et renommer.
Essaye avec une autre rom dès fois que cela viendrait de là.

Merci de cette réponse rapide

Pas de quoi.
N'oublie pas aussi de renommer le bios que tu recupere en "rom"(en minuscule et sans extension a la fin).

c'est clairement le tos qu'il te manque oui.
comme dis plus haut il faut en effet renomer le tos.rom en rom sans extension et le mettre la --> $HOME/.DCaSTaway/bios directory.

pour voir les repertoire /. sous ton client ftp il te faudra forcer l'affichage des fichiers cachés dans l'option "serveur" si tu utilise filezilla.

bonsoir et encore merci de votre aide

plusieurs essais plus tard et meme en changeant de rom, je suis toujours en echec
il doit manquer une étape dans mes manip car je ne trouve pas le repertoire .DCaSTaway
je ne le vois pas dans filezila même en activant l'option ad hic

je ne le vois pas non plus dans dinguxcmdr alors que je vois bien d'autres .xx (mais pas dans filezila...)


mais je n'ai pas les bases...
