Update to v085r08 release. byuu says: Changelog: - follow the Laevateinn topic to get most of it - also added NMI, IRQ step buttons to CPU debugger - also added trace masking + trace mask reset - also added memory export - cartridge loading is entirely folder-based now FitzRoy, I'll go ahead and make a second compromise with you for v086: I'll match the following: /path/to/SNES.sfc/*.sfc /path/to/NES.fc/*.prg, *.chr (split format) /path/to/NES.fc/*.fc (merged format) /path/to/GB.gb/*.gb /path/to/GBC.gbc/*.gbc Condition will be that there can only be one of each file. If there's more than one, it'll abort. That lets me name my ROMs as "Game.fc/Game.fc", and you can name yours as "Game.fc/cartridge.prg, cartridge.chr". Or whatever you want. We'll just go with that, see what fares out as the most popular, and then restrict it back to that method. The folder must have the .fc, etc extension though. That will be how we avoid false-positive folder matches. [Editor's note - the Laevateinn topic mentions these changes for v085r08: Added SMP/PPU breakpoints, SMP debugger, SMP stepping / tracing, memory editing on APU-bus / VRAM / OAM / CGRAM, save state menu, WRAM mirroring on breakpoints, protected MMIO memory regions (otherwise, viewing $002100 could crash your game.) Major missing components: - trace mask - trace mask clear / usage map clear - window geometry caching / sizing improvements - VRAM viewer - properties viewer - working memory export button The rest will most likely appear after v086 is released. ]

Update to v079 release. byuu says: This release includes Nintendo Super System DIP switch emulation and improved PPU rendering accuracy, among other things. Changelog: - added Nintendo Super System DIP switch emulation [requires XML setting maps] - emulated Super Game Boy $6001 VRAM offset selection port [ikari_01] - fixed randomness initialization of S-SMP port registers [fixes DBZ:Hyper Dimension and Ninja Warriors] - mosaic V-countdown caches BGOFS registers (fixes Super Turrican 2 effect) [reported by zal16] - non-mosaic BGOFS registers are always cached at H=60 (fixes NHL '94 and Super Mario World flickering) - fixed 2xSaI family of renderers on 64-bit systems - cleaned up SMP source code - phoenix: fixed a bug when closing bsnes while minimized Please note that the mosaic BGOFS fix is only for the accuracy profile. Unfortunately the older scanline-based compatibility renderer's code is nearly unmaintainable at this point, so I haven't yet been able to backport the fixes. Also, I have written a new cycle-accurate SMP core that does not use libco. The aim is to implement it into Snes9X v1.54. But it would of course be prudent to test the new core first. [...then in the next post...] Decided to keep that Super Mario World part a surprise, so ... surprise! Realized while working on the Super Turrican 2 mosaic fix, and from looking at NHL '94 and Dai Kaijuu Monogatari 2's behavior, that BGOFS registers must be cached between H=0 and H=88 for the entire scanline ... they can't work otherwise, and it'd be stupid for the PPU to re-add the offset to the position on every pixel anyway. I chose H=60 for now. Once I am set up with the RGB monitor and the North American cartridge dumping is completed, I'll set it on getting exact timings for all these things. It'll probably require a smallish speed hit to allow exact-cycle timing events for everything in the PPU.

Update to v088r11 release. byuu says: Changelog: - phoenix has added Window::setModal(bool modal = true); - file dialog is now modal. This allows emulation cores to request data and get it immediately before continuing the loading process - save data is hooked up for most systems, still need to handle subsystem slot saves (Sufami Turbo, basically.) - toggle fullscreen key binding added (Alt+Enter for now. I think F11 is probably better though, Enter is often mapped to game start button.) - video scaling is in (center, scale, stretch), works the same in windowed and fullscreen mode (stretch hides resize window option), all in the settings menu now - enough structure to map all saved paths for the browser and to load BS-X slotted carts, BS-X carts, single Sufami Turbo carts Caveats / Missing: - Super Game Boy input doesn't work yet (due to change in callback binding) - doesn't load secondary Sufami Turbo slot yet - BS-X BIOS isn't show the data pack games to load for some reason (ugh, I hate the shit out of debugging BS-X stuff ...) - need mute audio, sync audio+video toggle, save/load state menu and quick keys, XML mapping information window - need cheat editor and cheat database - need state manager - need to sort subsystems below main systems in load menu (basically just see if media.slot.size() > 0) - need video shaders (will probably leave off filters for the time being ... due to that 24/30-bit thing) - need video adjustments (contrast etc, overscan masks) - need audio adjustments (frequency, latency, resampler, volume, per-system frequency) - need driver selection and input focus policy (driver crash detection would be nice too) - need NSS DIP switch settings (that one will be really fun) - need to save and load window geometry settings - need to hook up controller selection (won't be fun), create a map to hide controllers with no inputs to reassign
