I have just released VGB 4.5 for Windows and Linux. To give you all something to do for the holidays, VGB-Windows is now free for everyone to use and share. The new release adds dozens of new features and fixes accumulated since VGB 3.5 has been published several years ago. VGB 4.5 emulates GameBoy Light, GameShark, the tilt sensor, MBC7, TAMA05, and MMM01 memory mappers. There have been major fixes to GameBoy CPU and LCD controller emulation. The noise sound channel is much closer to the original in this version. I have also added support for translation patches (.IPS), custom palettes (.PAL), Instant Replay (F, and a semi-automatic Cheat Hunter tool (F5) to search for new cheat codes.
