v0.1 (Initial Release)

Messaged posted by Nutki originally from DS-Scene forum thread:

   Hi all at DS Scene

   About 5 years ago I have wrote partial gameboy emulator in C purely for fun, so it never gone public. To try some NDS programming I have just ported it NDS. As there is no DLDI emu realesed for NDS I decided to add support for it and release here. Rom selection menu is based on work done for StellaDS by spathi-wa from r4ds forums.

   Some emulator (mis)features:
   - no sound emulation
   - no or incorrect serial/ir/dma/cpu emulation
   - no realtime sync, game will go as fast as it can
   - full speed for games that use less than about 50% of GB CPU
   However some games are playable anyway.

   How to use:
   - copy rom files to /lameboy/ dir on your flash card
   - run lameboy.nds and select rom
   - in game keys:
   -- L+R - back to rom select
   -- Y - switch fullscreen upscaling on/off
   -- X - save persistant ram to .sav file
 
   Note that this is compatible with DLDI, and that the download below is prepatched with just the R4 DLDI file. Patch it for your specific device before loading it onto your card.
