Mass name and type changes. Save states are now compatible between 32- and 64-bit systems. Maybe. 2016-06-18 17:29:11 +00:00			`uint8_t GB_read_memory(GB_gameboy_t *gb, uint16_t addr);`
Add a safe memory read API 2021-11-26 11:54:28 +00:00			`uint8_t GB_safe_read_memory(GB_gameboy_t *gb, uint16_t addr); // Without side effects`

Stabilizing API: New joypad, debugger and reset APIs; internal APIs and direct struct access are no longer available without defining GB_INTERNAL. The SDL port uses the new “public” APIs, as well as most of the non-debug Cocoa code. 2017-04-17 17:16:17 +00:00			`#ifdef GB_INTERNAL`
Maybe one day GCC will stop being shit at handling __attribute__s 2021-11-07 12:13:52 +00:00			`internal void GB_dma_run(GB_gameboy_t *gb);`
