Diverse: ares v141 :: AEP Emulation Page - Emulation News

SystemsNintendo - SNES / Super Famicom

Fix detection of the Sufami Turbo base cartridge (Avoiding serial conflict with Sailor Moon SuperS - Fuwafuwa Panic).
Fix PowerFest '94 and Campus Challenge '92.
Add support for games with 256KB of SRAM (Notably used in rom hacks, but these hacks also work on real hardware).
Add support for the NTT Data Keypad
Fix SA-1 DMA to BWRAM banks 0x41 and above.

Nintendo - Game Boy Advance

Improve stop mode emulation, ensuring it only exits once the requested input is registered.
Improve interrupt timings (latch IE and IF for 1 cycle).
Add latches to DISPCNT background enable, object enable and force blank; these now correctly take effect after 3 scanlines.
Improve SIO register handling.
Fix an off-by-one error with BG mosaic handling.
Fix an oversight in OBJ mosaic at x=0. Improve OBJ timing: OBJs are now correctly rendered one scanline in advance, and OBJ PRAM access timings are closer to hardware.
Add a 2-cycle synchronizer and improve halted CPU timings
Selectively synchronize CPU and APU, allowing for the removal of the compile time 'PERFORMANCE' profile. (Greater accuracy in Release builds with no performance downsides).
Small improvements to PPU timing.
Added support for the Pixel Accuracy toggle; significant performance increase when pixel accuracy is disabled.

Nintendo - Nintendo 64

Remove the 'devertualizeFast' performance optimisation from code block lookups: this was proven to compromise correctness/accuracy.
Refactor devirtualize to return additional context for memory access, reducing code duplication in-memory operations.
Use JIT only when running code from i-cache.
Add support for 40 Winks (Aftermarket).
Add support for Xeno Crisis (World) (Aftermarket)
Allow for Pak swapping on Controller Port 1 (You can now change between Controller Pak/Transfer Pak/Rumble Pack at runtime).
Fix instruction trace debugging when using the recompiler.
Add support for multi-byte writes to the GDB debugger.
Use different GDB signals for the various exception types.
Allow arbitrary and possibly unaligned writes to RDRAM through GDB.
Add unusual warning when software uses CACHE on uncached addresses
Refactor JIT to remove an extra function call (instructionEpilogue) per instruction.

Sega - Mega Drive / Genesis / 32X / CD

Synchronize components more regularly when emulating 32X; this fixes a regression that caused 'Knuckles Chaotix' to be broken in ares v140.
Add an option to enable the TMSS "Produced by or under license from..." screen.

Other

Stage resources into the output directory on Linux; allowing running self-compiled builds without running 'make install' first.
Address some possible uses of uninitialized variables.
Enable the use of loading higan-style rom folders when using the command line
Update librashader integration for librashader ABI 2

MacOS fixes

Display errors from the shader loader in metal, easing debugging of librashader.
Add bounds checking for table view context menus; fixes a crash when right-clicking beyond the bounds of defined rows in a table.
Fix an issue where librashader did not function on macOS versions lower than 12 (Monterey) when compiled by CI
