It is a planned feature. I build the architecture so it is possible to add support for that later.

Awesome!

Using your latest changes, I was able to play the Emscripten version of Bugz full screen at 60 fps on a three year old Chromebook that retailed for $199 back when it was brand new. Both the sound and video were perfect. Color me impressed!

This is the first time I've cross-compiled a Windows executable on a Linux system, but I successfully created cuzebox.exe from a Debian system, and it runs on a Windows 7 machine I found.

The only problem I ran into is if tried to maximize or resize the window, then it would crash, saying something happened within the SDL2.dll module. Pressing F2 followed by F4 tore down the GUI and recreated it at a smaller size, without a crash; and the same goes for pressing F2 followed by F4 again, it tore down the GUI and recreated it back at its original size, without a crash.

It could very well be that this Windows machine has buggy drivers—it was a fresh install of Windows 7 Enterprise, and I did not run Windows Update at all, though it also crashes when I try to resize it under Wine.

Re: CUzeBox - a new Uzebox emulator in progress

Post by Jubatian » Wed Sep 21, 2016 10:28 am

It could be that I missed something in interfacing SDL proper. I have Wine (and tested building and starting the emulator in it), so if the crash is reproducible there I should find what could cause it.

Crashing for resizing is weird though since there is nothing in my code handling resize events (so it is all done by SDL itself, as I understand it, the renderer should take care of everything transparently).

I found something related, which could be it:

https://forums.libsdl.org/viewtopic.php ... 69c95a0031

The commit fixing it is rather fresh (June, 2016). Are you sure the SDL2.dll you use has this fix?

It bugs me that I could be using an unsupported texture format (by the hardware), but I was unable to find anything to truly request some supported format. As I poked around in Uzem, I think the method it uses neither would definitely create a native format texture, it just creates a surface without specifying its arrangement and it isn't documented anywhere what exactly it would default to. Surfaces are just for compatibility in SDL2, if Uzem works well, I lean to think that it is merely by chance: that whatever default the surface creation provides just happens to be a supported format for some machines.

Damn. I found it. Line 387 in this source code. If you passed 0 as format for SDL_CreateTexture, it would use the first native format provided by the renderer. This isn't documented in SDL_CreateTexture, although could be useless if the renderer provided a rather arbitrary format there (such as indexed color even if it supported RGBA). The correct way could be using SDL_RendererInfo to find out what the renderer has and choose one of those. Messy thing, it doesn't seem like I could shortcut to just ask for any 32 bit, 8 bit per component format...

I did it! I mean I implemented a proper query for the native format, so now the emulator should use it! In particular on my PC this gives a very substantial kick in performance (about 20 percents, some games peak near a ridiculous 400%, well, now compare this to that a year ago I was happy if the Halloween demo broke the 25MHz barrier on the then-current Uzem...), not something insanely useful though as it has no effect on the Emscripten build.

Hopefully it also gets that pesky Windows SDL bug going away. And hopefully it doesn't break anything (as supporting multiple pixel formats also comes with that I can't simply test them all), I would be particularly interested in what happens on a Big Endian machine.

I see that you added the ability to use Uzem's keymappings (yay!), but you forgot to switch the location of the Select button. Select should be mapped to the Tab key.

Edit: Uzem's full keymappings are:

Code: Select all

            Up Down Left Right A B X Y Start Sel LShldr RShldr
NES:        ----arrow keys---- a s     Enter Tab              
SNES 1p:    ----arrow keys---- a s x z Enter Tab LShift RShift
  2p P1:     w   s    a    d   f g r t   z    x     q      e  
  2p P2:     i   k    j    l   ; ' p [   n    m     u      o

Will this be able to create new files? It would be very convenient to make a simple internet utility that occupies the SD card with all roms.

It should be able to create new files (not "will", it already has this implemented). You can do it by first setting up the FAT, then writing the file contents. If it detects that what you write belongs to a proper file by the Virtual FAT, but one which doesn't exist on the host, it creates the file. You can also expand files (increasing file size), and it also supports fragmentation.

Artcfox: I fixed that bug yesterday, it wasn't intentional.

Re: CUzeBox - a new Uzebox emulator in progress

Awesome! I just ordered an XBox 360 Wired USB controller, so Tuesday I'm hoping to test it with Uzem to make sure it works, and then hopefully we'll be able to add joypad support to CUzeBox.
