Release GnGB a Game Boy and Color Game Boy emulator for Testing


@dgame : when will you release the new version ?


btw.: thx for your great work ;)
 
LOL, you caught me! I've been having fun with PanMAME lately. The updated GnGB (mainly updates to configuration options in the launcher and updated documentation) is on my SD and ready to be packaged and tested.


Will post it here shortly, thanks for the reminder.
 
New version:


If you have an existing appdata/gngb/.gngb/gngbrc file it will NOT be over written and you will have the previous key mappings, you can either delete or rename the gngbrc file or edit the map_key line.

Thx for the update !! works and looks great ! but could you implement more platettes ( like in ohboy for the caanoo ), if it's possible.


Oh, I saw that gngbrc : http://wiki.open-slx...b/sample_gngbrc


so, can we just insert other palettes by changing the numbers ? If so, where can I get the "colour-codes"


edit.: I saw the source and it says :

Palette must be define in your gngbrc file (see sample_gngbrc)

so we only have to know the combinations like


0xB8A68D,0x917D5E,0x635030,0x211A10anybody knows where to get them ?


edit.: jep, it works :) I found a page with a few palettes, they work well :) If anybody wants to try : http://pocketheaven....opic.php?t=7139


but does sb know the codes from ohboy ?


here are some from the gnuboy rc : http://code.google.com/p/gnuboy/source/browse/trunk/etc/palettes.rc?r=19

As already inquired by others: Could you please publish this to http://repo.openpandora.org ?


Concerning your PND package: Please set the MOST ILLUSTRATIVE PIC as PRIMARY in the PND PXML definition, as many contexts consider only the first pic: MiniMenu preview, Repo RSS feed, PNDManager app info (more pics on demand), etc. http://pnd.to/previewpic


For an emulator illustrative would be a menu showing an interesting feature, such as the game state save/recall or a game with an overlay, etc, or at best a composite of multiple features.
