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 :/

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 :/

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,

Update to v088r03 release.
byuu says:
static vector<uint8_t> file::read(const string &filename); replaces:
static bool file::read(const string &filename, uint8_t *&data, unsigned
&size); This allows automatic deletion of the underlying data.
Added vectorstream, which is obviously a vector<uint8_t> wrapper for
a data stream. Plan is for all data accesses inside my emulation cores
to take stream objects, especially MSU1. This lets you feed the core
anything: memorystream, filestream, zipstream, gzipstream, httpstream,
etc. There will still be exceptions for link and serial, those need
actual library files on disk. But those aren't official hardware devices
anyway.
So to help with speed a bit, I'm rethinking the video rendering path.
Previous system:
- core outputs system-native samples (SNES = 19-bit LRGB, NES = 9-bit
emphasis+palette, DMG = 2-bit grayscale, etc.)
- interfaceSystem transforms samples to 30-bit via lookup table inside
the emulation core
- interfaceSystem masks off overscan areas, if enabled
- interfaceUI runs filter to produce new target buffer, if enabled
- interfaceUI transforms 30-bit video to native display depth (24-bit or
30-bit), and applies color-adjustments (gamma, etc) at the same time
New system:
- all cores now generate an internal palette, and call
Interface::videoColor(uint32_t source, uint16_t red, uint16_t green,
uint16_t blue) to get native display color post-adjusted (gamma, etc
applied already.)
- all cores output to uint32_t* buffer now (output video.palette[color]
instead of just color)
- interfaceUI runs filter to produce new target buffer, if enabled
- interfaceUI memcpy()'s buffer to the video card
videoColor() is pretty neat. source is the raw pixel (as per the
old-format, 19-bit SNES, 9-bit NES, etc), and you can create a color
from that if you really want to. Or return that value to get a buffer
just like v088 and below. red, green, blue are 16-bits per channel,
because why the hell not, right? Just lop off all the bits you don't
want. If you have more bits on your display than that, fuck you :P
The last step is extremely difficult to avoid. Video cards can and do
have pitches that differ from the width of the texture. Trying to make
the core account for this would be really awful. And even if we did
that, the emulation routine would need to write directly to a video card
RAM buffer. Some APIs require you to lock the video buffer while
writing, so this would leave the video buffer locked for a long time.
Probably not catastrophic, but still awful. And lastly, if the
emulation core tried writing directly to the display texture, software
filters would no longer be possible (unless you -really- jump through
hooks and divert to a memory buffer when a filter is enabled, but ...
fuck.)
Anyway, the point of all that work was to eliminate an extra video copy,
and the need for a really painful 30-bit to 24-bit conversion (three
shifts, three masks, three array indexes.) So this basically reverts us,
performance-wise, to where we were pre-30 bit support.
[...]
The downside to this is that we're going to need a filter for each
output depth. Since the array type is uint32_t*, and I don't intend to
support higher or lower depths, we really only need 24+30-bit versions
of each filter. Kinda shitty, but oh well.
