Update to v088r10 release. byuu says: ethos is going to be absolutely amazing. You guys are in for a treat :D I'm impressing the hell out of myself with how well-structured this code is, it's allowing me to do amazing new things. Just a small sampling of what's in store (and already implemented): The file browser will display folders as "[ folder name ]", and cartridge folders as "Game Name" (no extension, no /) [icons would be nicer, but well ... phoenix.] Folders are sorted above cartridge folders. Cartridge folders for other systems do not show up in the list. Not only are unique paths stored for each image type, your position in the list is saved across runs. Some voodoo was added to GTK+ so that all targets even scroll directly to that item when you open the list. Load->System->Enter restarts your last game. That sounds really simple and obvious, but it makes an -incredible- difference. Didn't realize it until I tried an implementation of it, wow. The input mapping list now lets you bind as many hotkeys as you want to any given input. So SFC::Port1::Joypad::B = Keyboard::Z or Joypad::Button1 ... no need to remap everything to switch between keyboard and joypad. Either one activates the key. There is a separate Hotkeys tab now. This should hopefully end the confusion about how to remap hotkeys that users experience. Hotkeys are different, too. Instead of OR logic, they use AND logic. So Fullscreen = Keyboard::Alt and Keyboard::Enter. Both must be pressed to enter the key. This lets you easily implement "super" modifier keys. The actual codebase has new features the old UI never had, and has about ~50% of the old functionality (so far, of course), yet is only ~25% as much code. The entire GUI no longer needs to pull in all the headers for each emulated system. It just needs a small interface header file. Then bind the entire system with exactly **two** lines of code. Everything is dynamically generated for you after that.

Update to v082r04 release. byuu says: So, here's the deal. I now have three emulators. I don't think the NES/GB ones are at all useful, but I do want them to be eventually. And having them have those pathetic little GUIs like ui-gameboy, and keeping everything in separate project folders, just doesn't work well for me. I kind of "got around" the issue with the Game Boy, by only allowing SGB mode emulation. But there is no "Super Nintendo" ... er ... wait ... uhmm ... well, you know what I mean anyway. So, my idea is to write a multi-emulator GUI, and keep the projects together. The GUI is not going to change much. The way I envision this working: At startup, you have a menubar with: "Cartridge, Settings, Tools, Help". Cartridge has "Load NES Cartridge", "Load SNES Cartridge", etc. When you load something, Cartridge is replaced with the appropriate system menu, eg "SNES". Here you have all your regular items: "power, reset, controller port selection, etc." There is also a new "Unload Cartridge" option, which is how you restore the "Cartridge" menu again. I have no plans to emulate any other systems, but if I ever do emulate something that doesn't take cartridges, I'll change the name to just "Load" or something. The cheat editor / state manager will look and act exactly the same. The settings panel will look exactly the same. I'll simply show/hide system-specific options as needed, like NES/SNES aspect ratio correction, etc. The input mapping window will just have settings for the currently loaded system. Video and audio tweaking will apply cross-system, as will hotkey mapping. The GUI stuff is mostly copy-paste, so it should only take me a week to get it 95% back to where it was, so don't worry, this isn't total GUI rewrite #80. I am, however, making all the objects pointers, so that I can destruct them all prior to main() returning, which is certainly one way of fixing that annoying Windows/Qt crash. Please only test on Linux. The Windows port is broken to hell, and will give you a bad impression of the idea: - menu groups are not hiding for some reason (all groups are showing, it looks hideous) - Timer interval(0) is taking 16ms per call, capping the FPS to ~64 tops [FWIW, bsnes/accuracy gets 130fps, bgameboy gets 450fps, bnes gets 800fps; all run at lowest possible granularity] - the OS keeps beeping when you press keys (AGAIN) Of course, Qt and GTK+ don't let you shrink a window from the requested geometry size, because they suck. So the video scaling stuff doesn't work all that great yet. Man, a metric fuckton of things need to be fixed in phoenix, and I really don't know how to fix any of them :/

bgb - Game Boy, Super Game Boy, and Game Boy Color emulator

Update to v082r18 release. byuu says: There we go, the GUI is nearly feature-complete once again. All cores now output their native video format (NES={emphasis}{palette}, SNES=BGR555, GameBoy={ bright, normal, darker, darkest }), and are transformed to RGB555 data that is passed to the video renderer. The video renderer then uses its internal palette to apply brightness/contrast/gamma/ramp adjustments and outputs in RGB888 color space. This does add in another rendering pass, unfortunately, but it's a necessary one for universal support. The plan is to adapt all filters to take RGB555 input, and output RGB555 data as well. By doing this, it will be possible to stack filters. However, it's a bit complicated: I need to plan how the stacking should occur (eg we never want to apply scanlines before HQ2x, etc.) Added input frequency adjustments for all three systems. I can easily get perfect video/audio sync on all three now, hooray. Long-term, it seems like we only really need one, and we can do a video/audio delta to get an adjusted value. But for now, this gets the job done. Added audio volume adjust. I left out the balance for now, since it's obviously impossible to balance the NES' single channel audio (I can duplicate the channel, and do twice the filtering work, but ... why?) I replaced NTSC/PAL TV mode selection with an "Enable Overscan" checkbox. On, you get 240 lines on NES+SNES. Off, you get 224 lines on NES+SNES. Also added aspect correction box back. I don't do that gross PAL distortion shit anymore, sorry PAL people. I just scale up the 54/47*(240/224) aspect correction for overscan off mode. All memory is loaded and saved now, for all three systems (hooray, now you can actually play Zelda 1&2.) Added all of the old bsnes hotkeys, with the exception of capture screenshot. May add again later. May come up with something a bit different for extra features. Re-added the NSS DIP switch setting window. Since geometry is saved, I didn't want to auto-hide rows, so now you'll see all eight possible DIPs, and the ones not used are grayed out. Ultimately, nobody will notice since we only have DIPs for ActRaiser NSS, and nobody's probably even using the XML file for that anyway. Whatever, it's nice to have anyway. Took FitzRoy's advice and single-item combo boxes on the input selection are disabled, so the user doesn't waste time checking them. I wanted to leave text so that you know there's not a problem. Qt disabled radio box items look almost exactly like enabled ones. Fixed lots of issues in phoenix and extended it a bit. But I was still having trouble with radio box grouping, so I said fuck it and made the panels show/hide based instead of append/remove based. That's all for stuff off the checklist, I did a bunch of other things I don't recall. So yeah, I'd say the GUI is 100% usable now. This is my opinion on how multi-platform GUIs should be done =) Oh, I figure I should mention, but the NES core is GPLv3, and all future SNES+GB releases will be as well. It's a move against Microsoft's Metro store.
