Lior Halphon 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
Lior Halphon 249acb04cc Verified some timings on a DMG. Fixed palette write conflict timing (Although the fix kind of implies time traveling). Closes #65 2018-05-16 00:59:11 +03:00

Lior Halphon 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

Lothar Serra Mari 8f3fc1c2ad Fix check for SDL2 version 2018-04-22 16:20:11 +02:00
Lothar Serra Mari 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...

Lothar Serra Mari 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.

Lothar Serra Mari 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).
