Bentley A few thoughts: 1. It is using -std=gnu11, so we need a COMPILER=base-clang ports-gcc line otherwise it will fail on base-gcc archs. 2. There is a -Werror in Makefile and a hardcoded -O2 in libretro/Makefile that are worth removing. 3. When I ran `make port-lib-depends-check`, it said LIB_DEPENDS devel/sdl2 not needed for emulators/sameboy,-libretro ? Changing LIB_DEPENDS to LIB_DEPENDS-main makes the warning go away. ~Brian

Fullscreen works, and so does the gamepad (XBox 360 controller), with the caveat that up and down on the left stick are reversed and there doesn't seem to be a way to flip axes. The D-pad works fine, however. I tested it with 2 GameBoy Color ROMS including the free puzzler Snakebird.gb [1] with no issues other than audio distortion and the reversed Y axis on the gamepad. ok thfr@ [1] https://fb1.itch.io/snakebirdgb

Hi, SameBoy is a SDL-based Nintendo Game Boy and Game Boy Color emulator. SameBoy is extremely accurate and includes a wide range of powerful debugging features, making it ideal for both casual players and developers. In addition to accuracy and developer capabilities, SameBoy has all the features one would expect from an emulator, from save states to scaling filters. libretro-sameboy provides a Nintendo Game Boy and Game Boy Color emulation core to the RetroArch emulator frontend, based on SameBoy. SameBoy is to my knowledge the most accurate Game Boy emulator in existence. It is certainly more accurate than Gambatte, the most accurate emulator in our tree. And unlike Gambatte, SameBoy is actively maintained. For general usage I still usually recommend mgba, as it is quite accurate (more than enough for people just playing games) and has a fairly strong pledge on OpenBSD. But SameBoy is an important emulator for anyone doing Game Boy development. I previously submitted this about a year ago. At the time I mentioned issues with audio speed, but I can no longer reproduce those problems. In addition, upstream has integrated my portability patches. ok? -- Anthony J.

NEW: emulators/sameboy (with audio[?] issues)
Hi, SameBoy is a SDL-based Nintendo Game Boy and Game Boy Color emulator. SameBoy is extremely accurate and includes a wide range of powerful debugging features, making it ideal for both casual players and developers. In addition to accuracy and developer capabilities, SameBoy has all the features one would expect from an emulator, from save states to scaling filters. In case anyone wonders why we would want another Game Boy emulator: compared to the three Game Boy emulators we have that are still relevant (Gambatte, mGBA, VBA-M), SameBoy is more accurate to the hardware, and it's actively developed (unlike Gambatte, the next most accurate). Unfortunately the SDL frontend has noticeable audio artifacts and runs quite slow. I remember seeing similar symptoms with mGBA some time ago that turned out to be related to audio buffer size and sample rate. But blindly fiddling with audio constants and variables in SameBoy's SDL/main.c didn't get me anywhere. The libretro core plays fine, so the problem definitely lies in the SDL frontend somewhere. Also, if anyone has access to a macOS system, I'd appreciate testing of this pull request on that platform. It would be easier to get the OpenBSD patches upstreamed if I had confirmation that they don't break the macOS build. https://github.com/LIJI32/SameBoy/pull/143 -- Anthony J.
