* Corrected several instruction timings and interruption timing.

* Corrected scrolling visuals for several games (adding timing count for STIC). * Corrected bug in Overflow flag for SUB/CMP. Several major improvements have been made to this core recently thanks to nanochess. FreeIntvįreeIntv is an Mattel Intellivision emulator core. * Should now handle paths with special characters when using Windows. * A Pixel Perfect (PAR 1:1, DAR 16:15) option was added.

“Homebrew multicarts” here refers existing multicart ROMs modified to replace one or two games, and make make changes to the menu code to work better in some other emulators. (I have done such a thing for NintendulatorNRS.)įinally, a small number (I counted two) homebrew multicarts from nesbbs no longer work with the newer, more hardware-accurate emulation. I see no way of solving this short of creating a database of valid DIP switch positions for every known file hash. The problem remains that the code does not know up to which value the address mask should shift, so that “76 in 1 CHEER – TECH” acts strangely from the fourth to the eighth reset. (And “BMC-FK23CA”, previously described as explicitly denoting a DIP switch, is used for a few carts that do not like DIP switch changes between resets at all.) I introduced a new heuristic that worked for all files in the database. Some carts act quite erratically when the address mask changes on every soft reset, and the old code to decide that did not work well for. The heuristic that I used works for all UNIF files that I had in my possession.Īnother issue is the DIP switch. For example, several BMC-FK23C(A) are actually FS005. UNIF files remain a problem, since the UNIF file loader does not use that database, and the four UNIF MAPRs (BMC-FK23C, BMC-FK23CA, BMC-Super24in1SC03, WAIXING-FS005) do not neatly correspond to the actual hardware variants. I made sure that I have every mapper 176 ROM file that previously was in ines-correct.h.

This update rewrites the mapper 176 emulation accordingly and adds all affected ROM images knownst to me to the ines-correct.h database. FCEUmmįCEUmm is a Nintendo Entertainment System / Famicom emulator core.Ī number of submappers have been assigned to mapper 176 () based on real-hardware tests.

Some things that were added recently to this include software rendering upscaling support. SwanStation is a PlayStation1 emulator core. * IPU: Return contents of the bottom of the FIFO in CMD except FDEC/VDEC. Removes a GameDB hack for Arctic Thunder as it’s no longer needed thanks to the above CDVD improvement.

* GameDB: Remove SkipmMPEG patch for Arctic Thunder. This fixes a number of CDVD timing issues, e.g. * CDVD: Adjust read speed depending on if in inner/outer edge. * Fixed a memory access violation during init * Added language support for all EU and NA BIOS * Improved reliability of BIOS detection for language injection * Added notification to frontent about widescreen patches found or not found for the loaded content * Added function for sending message notifications to frontend * Added option to set System Language per game * Replace “Force Widescreen” option with “Aspect Ratio” option * Fixed the rumble issue where it doesn’t stop when triggered * Fixed a problem which prevented to select the correct HW rendererįixed null renderer problem that, if selected, freezed the frontend * Added userhack options: Align Sprite and Merge Sprite * Added bios list at runtime to libretro optionsĪdded fallback to default safe preset if speedhack option is disabled * Refactoring of core options based on libretro standardĪdded option to set pcsx2 Accurancy/Speed presets * Added widescreen, speedhacks options and some userhacks, some code refactoring and cleanup
