Here it comes. Not as many fixes as I expected to put in this release, but did not want to delay it any longer. There is no change to sound core so don’t expect any improvement there.

Remember what I said about no hardware bilinear upscaling in NDS in the last note? Actually I was wrong - you can get it with some simple tricks. So now you can toggle between no scaling / nearest neighbour / bilinear with Y button.

Changelog:

  * fixed: joypad register emulation (fixes Wario Blast)
  * fixed: GBC hdma (fixes Pokemon Crystal graphics)
  * fixed: interrupt flags emulation (fixes Bouble Bobble)
  * fixed: V-blank interrupt timing (fixes Altered Space)
  * fixed: split window emulation (fixes Donkey Kong graphics)
  * fixed: GB timer initialization (fixes Pokemon Pinball)
  * added: fake serial interrupts (fixes many early games)
  * added: RTC emulation
  * added: pseudo bilinear upscaling mode

RTC feature needs more explanation. I tested it with only one game - Pokemon Crystal, so it can be considered beta. The emulated time is always synchronized to NDS RTC and not affected by fast mode. It’s the same behaviour as in VBA and opposite to GNUBoy’s. Also save style is compatible to VBA, with one issue: I think there is no way to check time zone in NDS (as it is not set) so I fixed it to +2h. If your timezone is different you will get timeshift between Lameboy and VBA.

Updated list.
I had said I would add more games this time, but I lied. Just rechecking all of these games took about 2 hours. I may in the future do more however, but don't count on it any time soon.

Color Key:
Green: 60FPS with fullsound. Possible very minor sound/graphics issue.
Blue: Gameplay slowdown and/or major graphic errors with possible sound issues.
Red: Crashes/Not playable

I am really impressed by the improved scaling. It is a massive improvement over nearest neighbor scaling. Also the RTC works well. Maybe in the next realease wee will see support for the game boy color pseudo coloring pallets effect see on original gb games played on a gbc or gba. Also support for super gameboy borders and pallets would be cool.
