This allow you to avoid to change the current rendering mode each time you're switching from or to fullscreen. For instance, if you prefer "2xSAI render" in fullscreen and "double render" in windowed, just choose once "double render" in windowed then go to fullscreen, change to 2xSai... Now if you go back to windowed mode, the "double render" is chosen and when you go back to fullscreen mode, "2xSAI render" is activated. - "strech" feature isn't available for all scanlines renders & 2xSAI render when you are in fullscreen. NETPLAY : --------- First, be sure you have the kailleraclient.dll file in your Gens directory (anyway, the emu doesn't start if isn't the case). Well, go to 'file->Netplay' then the kaillera server selection dialog appear ... Don't forget to specify a user name. if you want to play on the NET, be sure that you're connected (^-^), if you want to play on local network, just specify the IP of the kaillera server (you can download the server at http://www.kaillera.com). Choose the server where you want to play, then a other dialog appears and you can see others players connected to the server and theirs status (idle, playing ...), also you can see the current created games, if you wish to play one of them (and the status is waiting) then just 'join' the game ... YOU HAVE TO HAVE THE EXACT SAME NAME OF THE ROM (so better to use goodgen to rename your roms). But you can create a game by clicking on the 'Create new game' button, then a list of game should appear (it's the list of all the roms you have in your last rom loaded directory). Then you can wait for others players and start the game alone ;) When you want to stop the game, YOU HAVE TO CLOSE THE ROM (Menu 'File->close rom' or Ctrl+C) then you can start an other netplay party. If you want to exit Gens, you have to close all the kaillera dialog (the little before to avoid crashe ... a bug of kaillera), then you can close Gens. Sorry for all these convenients, but Kaillera has be made for MAME first and Gens works in a complety different way ... If you want more informations about how use Kaillera, check the homepage at http://www.kaillera.com For others emulator authors who want to be compatible with Gens for NETPLAY, here's the format of the data sent with kailleraModifyPlayValues function for one player (2 bytes of lenght) : F E D C B A 9 8 7 6 5 4 3 2 1 0 1 1 1 1 M X Y Z S A B C U D L R o t p o e i d a w f g e r n t h t t Value : 0 if the button is pressed and 1 in other case. ----- | FAQ | ----- Q : I got the following message : "Error with Query Interface", how fix it ? A : You just have to reinstall directX 7.0 (or above). Q : I can't set my joypad because keys are automatically pressed (quickly), what's the problem ? A : Reinstall your joypad in the window joystick/joypad panel then reinstall DirectX, if still not fixed ... no luck. Q : 2xSAI doesn't work in fullsreen ! A : 2xSAI works perfectly in fullscreen, use F11/F12 to switch the current render mode. Gens has a separate render mode for fullscreen and windowed mode. Q : Game Genie doesn't work !!! A : Download the Gens manual at http://www.genesisproject.co.uk which explain how use it. Q : Where i can find roms ? A : it's easy to find roms with search engine, don't forget that isn't legal to have roms if you don't have the original game, i can't be responsible for your acts. Q : How exiting Netplay ? A : First, you have to close the rom (Ctrl+C) then close the Kaillera client windows. Q : Netplay sometimes crashs ... A : I know, Kaillera library has some bugs, Gens has others so ...
