@jmarsh Any plans to add PPC jit code to main dosbox branch?

Hi, Did anyone merge 3dfx emulation to PowerPC version? I did it on MorphOS and it seems the emulated card is not working correctly.

Hi, i need to make some tests but maybe this part in vga_draw.cpp would be a better place to do endian conversion, it would give clean BE output and doesn't require PMAKE changes, it could be also Altivec accelerated in easy way. I'll make some tests and let you know (and need to check how memcpy is …

Mask aren't enough as Green bits aren't placed together. I'll probably go hacked way and link special static SDL library (instead of dynamic one) so i can break SDL api

@Jmarsh Ok, so maybe I'll explain: -It seems that Dosbox VGA emulation provide lines in LE format for 16bit -Dosbox gui/scalers part doesn't convert endian, just pass data as SDL Surface (all these PMAKE defines) -SDL Surface is always (or should be) in BE for PowerPC (https://discourse.libsdl.org …

It depends on screen mode you use for fullscreen. Conversion for 32bit screen also should be added.

@All Oh, there is really good news now! Kcroft does check it on his Linux PPC on PowerMac, and he have exactly the same issues (absolutely the same look as we have), see further here: https://github.com/dreamer/dosbox-staging/issues/144#issuecomment-578533293 So Jmarsh's Wii there as an exception. …

So MorphOS also has problems with 32bit and 16bit screens. 32bit is easy as it can be fixed using RGBA mask. 16bit can't be fixed such way. SDL Surfaces have to be in native format (big endian for PPC) and implementation should convert it to GfX card destination format (RGB16 with littleendian). In …

Check if the same thing occurs with the frameskip set to 1 or 2. Hi, so i got only ~16 fps values with frameskip 1, 2, 3. MorphOS has DFS2 turned on on PowerBooks and ImacsG5 so on PowerMacG5 it always runs full speed. btw. What about playing with cache size defines, is it worth playing with them?

Hi, First of all, big thx for writing PPC dynarec. I've made a port for MorphOS operating system and it works pretty well. (only //#define USE_SDA_BASE was needed). MorphOS runs on PowerMacs mostly and i'm testing DosBox on my PMac G5 2.3 PCIe. There is one strange thing regarding speed. I've …
