45c73e0175 Replaced the is_cgb bool with a more future compatible model enum. Removed the GB_init_cgb API and replaced it with an extended GB_init and GB_switch_model_and_reset APIs that now receive a model parameter. Increased the struct version. 2018-06-16 13:59:33 +03:00

855ffb490a A HBlank interrupt cannot occur in the last M-cycle of HBlank. Correct emulation of STAT access conflicts on the CGB (Test: CPU-E, single speed only). Fixes a minor graphical glitch in Pokémon Puzzle Challenge. 2018-05-25 23:42:36 +03:00

713dc02e46 A bit tacky, but T-cycle accurate emulation of LYC write conflicts on the CGB. Only single speed mode verified. Closes #54 2018-05-11 12:38:55 +03:00

ef670986c6 Rewrote PPU (currently only emulates DMG correctly) to use the new timing mechanism. Removed “future interrupts” (No longer required because SameBoy is now T-cycle based) 2018-02-25 00:48:45 +02:00

441781cbe9 Libretro .o files are now in the build/obj folder and are suffixed with _libretro (since they have different compilation flags). This also lets us rename gbmemory.c/h back to its original name. 2017-10-12 19:42:30 +03:00
