Re: Hifiberry Dac and Retropie?

Hi ! Can you tell us what you did to get it to work ?
Do gaming distros (like Recalbox) work with it with no added latency ?
Cheers !

Re: Speeding up Dosbox

Okay, I finally found a satisfying solution : using the dosbox build from the RetroPie project. Dynamic mode is enabled, no opengl output (only surface) but scalers work and display is fullscreen. The result is pretty good with the "tv2x" scaler (nice scanlines). There is tearing though (and enablin...

Re: DOSBOX with GLES2 + tv shader + dynamic recompiler

Hi ! Thanks for the reply :) Would it be difficult for someone else to add scanlines the dosbox/sdl2, based on your previous patch ? I guess we could fall back to this dosbox fork that supports libsdl2 and pixel shaders : https://github.com/duganchen/dosbox/blob/master/ENHANCEMENTS.md I have trouble...

Re: DOSBOX with GLES2 + tv shader + dynamic recompiler

OK, I applied the patch to the latest CVS (or SVN I'm a bit lost) and specified the configuration options as suggested above. It compiled properly with dynrec and gles. However when starting dosbox (from X) I get the following message : libEGL warning : DRI2: failed to authenticate dosbox: gles_ctx....

Re: DOSBOX with GLES2 + tv shader + dynamic recompiler

Hi ! This is exactly what I was looking for :) I'm planning to use dosbox on my Pi 3 with pixel shaders and an external MIDI synth (which should significantly unload the CPU and improve the music). Is it possible to have up to date information for building it on the Pi 3 ? Is the patch still working...

Re: Speeding up Dosbox

Hmm, I have another question ! I modified config.h as specified above but the dynamic core is not available. Any idea why, maybe another dependency ? Hmm, I'm pretty sure this is due to the architecture setting which doesn't fit the Pi 3 one. Probably I should put armv8-a instead. Edit : just stumbl...

Re: Speeding up Dosbox

I just made this test : I got this snapshot from the dosbox fork : https://github.com/duganchen/dosbox/releases On my Happi Game Center distro, I unarchived it, did ./autogen.sh && ./configure && make (after raising the /tmp size in /etc/fstab) it built properly.

Re: HAPPI game center

This would probably be most wise (removing the binaries), indeed, even though I'm pretty sure the harsh tone is not necessary (and clearly disheartening). Moreover, the backstory is real in case anyone cares. Edit : I correct myself : the "harsh tone" is subjective. After re-reading your posts again...

Re: MAME4ALL for Pi

I've not tried RetroPie for a long time ; I'm not sure they use the right versions of MAME / FinalBurnAlpha. But if they use Squid's MAME4ALL / PiFBA this is good. Those are definitely the best compromises in terms of speed and compatiblity ! You need both MAME4ALL and PiFBA. PiFBA supports fewers b...

Re: MAME4ALL for Pi

Scanlines support is built-in in MAME4ALL (and PiFBA), so no problem. They come at no cost as they are implemented in a shader. Enable them in the .ini file (but you have to disable smooth stretch before unfortunately). As I said above, there are 2 issues however : 1) as you cannot have both effects...

Re: MAME4ALL for Pi

I made a quick and absolutely dirty hack to force the scanlines mode of mame4all to display a picture that would be a integer multiply of the game base resolution. And, it looks definitely better, scrolling is better, less flickering etc. I wish I could do it cleanly, and also in smooth_stretch_mode...
