Version 0.8 (beta) - June 27, 2021

Even though this release is called "beta" it is super stable and should play 99% (or more) of all Game Boy and Game Boy Color games, given that the cartridge ROM size of the game is up to 1 MB (on a MEGA65 R3 machine, otherwise up to 256 kB).

What is new?

  • HDMI video and HDMI audio support (for MEGA65 R3 machines only)
  • Migrated the core's screen resolution to the 720p @ 60Hz standard (1280x720 pixels) for better HDMI compatibility (coming from SVGA 800x600 @ 60 Hz)
  • Smoother display (less flickering/artifacts) due to double-buffering
  • Improved the stability and robustness of the SD card reading
  • Smart support of both MEGA65 SD Card slots: If a card is inserted into the backside ("external") slot then this card is used, otherwise the card in the bottom/trapdoor ("internal") slot is used. Moreover, you can switch to the internal SD card in the file browser using F1 and to the external SD card using F3.

Why is the release still called "beta"?

  • No HyperRAM: Cannot play games that have ROMs larger than 1 MB (MEGA65 R3 machine) or 256 kB (MEGA65 R2 machine)
  • Flickering in rare situations due to no frame blending
  • No savegames (i.e. no battery buffered cartrige RAM)

What is new?

  • Much better compatibility (games and demos) due to support for more MBCs

  • Only supports MEGA65's bottom SD card slot, the rear slot is ignored
  • Flickering in rare situations due to no double bufffering, no frame blending
  • No savegames (i.e. no battery buffered cartrige RAM)

Version 0.6 (alpha) - March 23, 2021
