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

ca571c6fa5 SDL2: Update to SDL_OpenAudioDevice()
Instead of the legacy SDL_OpenAudio() method, we now use the newer
SDL_OpenAudioDevice() functions. This fixes audio in Windows if the SDL
version is 2.0.6 or higher.

It also allows us to use 48kHz audio for Windows (96kHz somewhat works
too, but since we don't get absolutely smooth audio with it, I'd stick
with 48kHz for now until we find a solution. 44.1Khz is available as
fallback for SDL 2.0.5 and lower. Yes, the 2.0.5 to 2.0.6 transition was
quite harsh in terms of Windows audio support...

2407304177 SDL2: Write battery file information before issueing RESET_COMMAND
Before performing the GB reset, we should perform a GB_save_battery.

Otherwise, resetting the emulation will kill ("kill" as in simply don't
write them into the .sav) all changes made to the battery save since
sameboy was started.

7fe86cec59 Fix savestates in SDL2 port
Because SDL_SCANCODE_0 comes *after* SDL_SCANCODE_9 in the SDL keycode
table, we have to check if the keycode is between >=1 and <=0. We also
have to substract SDL_SCANCODE_1 in order to set command_parameter
properly.

Errata: Currently, the savestate created with CTRL+0 is created, but
refuses to load on Windows (working fine on Linux).
