NanoBoyAdvance is a cycle-accurate Game Boy Advance emulator.
It aims to be as accurate as possible, while also offering enhancements such
as improved audio quality.
Changes:
- UI: implement a 'Use integer scaling' option
- UI: allow limiting the screen scale
- UI: allow accessing the menu during fullscreen gameplay
- UI: allow setting a custom save folder
- Core: implement save compatibility with mGBA 0.10.0+
- Core: implement basic support for the mGBA logging interface
- PPU: rewrite the PPU to be mostly cycle-accurate (fixes #241, #230, #229,
#208, #141)
- PPU: implement the GREENSWAP register
- PPU: use the 6-th green channel bit during blending
- PPU: round the blending result to the nearest integer
- ARM: fix a minor timing oversight in ARM mode
- ARM: SWP and SWPB should lock the bus (no DMA interleave is possible)
- ARM: do not force-align mis-aligned PC in ARM mode
- Bus: allow the CPU to execute idle cycles in parallel to DMA
- Bus: more accurately emulate disabling the prefetch buffer
- Bus: force the first CPU access after a DMA to be non-sequential
- Bus: implement penalty for ROM code access during the last ROM prefetch cycle
(fixes #203)
- IRQ: delay IO writes by one cycle
- IRQ: delay update of the IE&IF condition for unhalting the CPU
- SIO: implement basic serial transfer timing (fixes #282)
- APU: emulate the master enable bit
- APU: cancel a potentially pending event whan starting a channel (fixes #278)
Scheduler: allow for (de)serialization of events for save states
Notes
- On Linux make sure SDL2, GLEW and Qt5 are installed
